Appendix DCO may be revised and supplemented from time to time upon the mutual agreement of the Parties to reflect the Interconnection of additional Metropolitan Exchange Areas pursuant to Section 4.6. 4.0 INTERCONNECTION PURSUANT TO SECTION 251(C)(2) 4.1 SCOPE This Section 4.0 describes the physical architecture for Interconnection of the Parties' facilities and equipment for the transmission and routing of Telephone Exchange Service traffic and Exchange Access traffic pursuant to Section 251(c)(2) of the Act. Such Interconnections shall be equal in quality to that provided by the Parties to themselves or to any subsidiary, affiliate or third party. Appendix ITR attached hereto and incorporated by reference prescribes the specific trunk groups (and traffic routing parameters) which will be configured over the physical connections described in this Section 4.0 to provide the facilities for the transmission and routing of Telephone Exchange Service traffic (as described in Section 5.0), Exchange Access traffic (as described in Section 6.0), LSV/BLI traffic (as described in Section 7.2), E911/911 traffic (as described in Appendix 911). Use of this physical connection shall be limited to the trunk groups described in Appendix ITR. GENERAL TERMS AND CONDITIONS PAGE 10 OF 52 SWBT/Optel J130 4.2 INTERCONNECTION COVERAGE The Parties shall provide for interoperation of their networks and shall interconnect their facilities as stated below: 4.2.1. Optel shall interconnect with SWBT's facilities as follows: a. In each SWBT exchange area in which Optel chooses to offer local exchange service, Optel, at a minimum, will interconnect its network facilities to: (a) each SWBT access tandem(s), and (b) to either each SWBT local tandem(s) or each SWBT end office(s) ("EO") subtending that local tandem(s). SWBT EOs and tandems through which Optel will terminate its traffic will be called SWBT Interconnection Wire Centers and are identified in Appendix DCO. As Optel initiates Exchange Service operations in additional SWBT exchange areas, SWBT and Optel shall agree upon additional SWBT Interconnection Wire Centers in each new exchange area. Optel agrees that if SWBT establishes additional local tandems in an exchange area within which Optel offers local exchange service, Optel will establish new trunk groups on its existing interconnection facilities so that SWBT may interconnect Optel trunks to the additional local tandem(s). b. Interconnection to a SWBT local tandem(s) will provide Optel local access to the SWBT end offices and NXXs which subtend that tandem(s), and to other Local Exchange Carriers ("LECs") (subject to Section 5.4) which are connected to that tandem(s). Interconnection to SWBT EO(s) will provide Optel access only to the NXXs served by that individual EO(s) to which Optel interconnects. c. Interconnection to a SWBT access tandem will provide Optel interexchange access to SWBT, IXCs, LECs and CMRS providers (subject to Section 7.3) which are connected to that tandem. Where an access tandem also provides local tandem functions, interconnection to a SWBT access tandem serving that exchange will also provide Optel access to SWBT's EOs with the same functionality described in (b) above. d. Where Optel requires ancillary services (e.g., Directory Assistance, Operator Assistance, 911/E911) additional interconnection to SWBT's Interconnection Wire Center(s) or special trunking will be required for interconnection to such ancillary services. 4.2.2. SWBT shall interconnect with Optel's facilities under terms and conditions no less favorable to Optel than those identified in Section 4.2.1 above. GENERAL TERMS AND CONDITIONS PAGE 11 OF 52 SWBT/Optel J130 4.3 METHODS FOR INTERCONNECTION Where the Parties interconnect, for the purpose of exchanging traffic between networks, the Parties may use the following interconnection methods of each Tandem and End Office identified in Appendix DCO making use of facilities they own or lease from a third party. 4.3.1 Physical Collocation Interconnection ("PCI") - Where Optel provides fiber cable and connects to its equipment located in the SWBT Wire Center. Optel owns and maintains Optel's equipment. 4.3.2 Virtual Collocation Interconnection ("VCI") - Where Optel provides fiber cable to SWBT for connection to Optel-designated basic transmission equipment dedicated solely for Optel's use, located in the SWBT Interconnection Wire Center. SWBT owns and maintains the basic transmission equipment at the SWBT Interconnection Wire Center. This option shall be consistent with the terms of SWBT's virtual collocation tariff. 4.3.3 SONET-Based Interconnection ("SBI") - Where Optel provides fiber cable to SWBT for connection to SWBT-designated basic transmission equipment located at the SWBT Interconnection Wire Center (SIWC) and dedicated solely for Optel's use. SWBT owns and maintains the basic transmission equipment. This option shall be consistent with SWBT's SBI tariff. 4.3.4 Leased Facility Interconnection ("LFI") - Where facilities exist, either Party may lease facilities from the other Party. 4.3.5 Mid-span Fiber Interconnection ("MSFI") - Where the Parties agree to interconnect through SONET technology, a Fujitsu originating line terminating multiplexer fiber optic terminal ("FOT") shall be used. Mid-Span Fiber Interconnection (MSFI) between Southwestern Bell Telephone (SWBT) and LSP can occur at any mutually agreeable, economically and technically feasible point between LSP's premises and a SWBT tandem or end office. This interconnection will be on a point-to-point SONET system over single mode fiber optic cable. 4.3.5.1 MSFI may be used to provide interconnection trunking as defined in Attachment ITR. 4.3.5.2 There are two basic mid-span interconnection designs: a. Design One: LSP's fiber cable and SWBT's fiber cable are connected at an economically and technically feasible point between the LSP location and the last entrance manhole at the SWBT central office. The Parties may agree to a location with access to an existing SWBT fiber termination panel. In these cases, the network interconnection point (POI) shall be designated outside of the GENERAL TERMS AND CONDITIONS PAGE 12 OF 52 SWBT/Optel J130 SWBT building, even though the LSP fiber may be physically terminated on a fiber termination panel inside of a SWBT building. In this instance, LSP will not incur fiber termination charges and SWBT will be responsible for connecting the cable to the SWBT facility. The Parties may agree to a location with access to an existing LSP fiber termination panel. In these cases, the network interconnection point POI) shall be designated outside of the LSP building, even though the SWBT fiber may be physically terminated on a fiber termination panel inside of an LSP building. In this instance, SWBT will not incur fiber termination charges and LSP will be responsible for connecting the cable to the LSP facility. If a suitable location with an existing fiber termination panel cannot be agreed upon, LSP and SWBT shall mutually determine provision of a fiber termination panel housed in an outside, above ground, cabinet placed at the physical POI. Ownership and the cost of provisioning the panel will be negotiated between the two parties. b. Design Two: LSP will provide fiber cable to the last entrance manhole at the SWBT tandem or end office switch with which LSP wishes to interconnect. LSP will provide a sufficient length of fiber optic cable for SWBT to pull the fiber cable to the SWBT cable vault for termination on the SWBT fiber distribution frame (FDF). In this case the POI shall be at the manhole location. In this instance, LSP will not incur fiber termination charges and SWBT will be responsible for connecting the cable to the SWBT facility. Each Party is responsible for designing, provisioning, ownership and maintenance of all equipment and facilities on its side of the POI. Each Party is free to select the manufacturer of its Fiber Optic Terminal (FOT). Neither Party will be allowed to access the Data Communication Channel (DCC) of the other Party's FOT. The Parties will work cooperatively to achieve equipment compatibility. 4.3.5.3 The Parties will mutually agree upon the precise terms of each mid-span interconnection facility. These terms will cover the technical details of the interconnection as well as other network interconnection, provisioning and maintenance issues. GENERAL TERMS AND CONDITIONS PAGE 13 OF 52 SWBT/Optel J130 4.3.5.4 The LSP location includes FOTs, multiplexing and fiber required to take the optical signal handoff from SWBT for interconnection trunking as outlined in Appendix ITR. 4.3.5.5 The fiber connection point may occur at several locations: a. a location with an existing SWBT fiber termination panel. In this situation, the POI shall be outside the SWBT building which houses the fiber termination panel; b. a location with access to an existing LSP fiber termination panel. In these cases, the network interconnection point (POI) shall be designated outside of the LSP building, even though the SWBT fiber may be physically terminated on a fiber termination panel inside a LSP building; c. a location with no existing SWBT fiber termination panel. In this situation, SWBT and LSP will negotiate provisioning, maintenance and ownership of a fiber termination panel and above ground outside cabinet as a POI and for connection of the fiber cables; d. a manhole outside of the SWBT central office. In this situation, LSP will provide sufficient fiber optic cable for SWBT to pull the cable into the SWBT cable vault for termination on the SWBT FDF. The POI will be at the manhole and SWBT will assume maintenance responsibility for the fiber cabling from the manhole to the FDF. 4.3.5.6 The SWBT tandem or end office switch includes all SWBT FOT, multiplexing and fiber required to take the optical signal hand-off provided from LSP for interconnection trunking as outlined in Appendix ITR. This location is SWBT's responsibility to provision and maintain. 4.3.5.7. In both designs, LSP and SWBT will mutually agree on the capacity of the FOT(s) to be utilized. The capacity will be based on equivalent DS1s that contain trunks and interLATA traffic. Each Party will also agree upon the optical frequency and wavelength necessary to implement the interconnection. The Parties will develop and agree upon methods for the capacity planning and management for these facilities, terms and conditions for over provisioning facilities, and the necessary processes to implement facilities as indicated below. These methods will meet quality standards as mutually agreed to by LSP and SWBT. 4.3.5.8 AVOIDANCE OF OVER PROVISIONING - Underutilization is the ------------------------------ inefficient deployment and use of the network due to forecasting a need for more capacity than actual usage requires, and results in unnecessary costs for SONET systems. To avoid over provisioning, the Parties will agree to joint facility growth planning as detailed below. GENERAL TERMS AND CONDITIONS PAGE 14 OF 52 SWBT/Optel J130 4.5.3.9 JOINT FACILITY GROWTH PLANNING - The initial fiber optic ------------------------------ system deployed for each interconnection shall be the smallest standard available. For SONET this is an OC-3 system. The following list the criteria and processes needed to satisfy additional capacity requirements beyond the initial system. a. Criteria: - Investment is to be minimized; - Facilities are to be deployed in a "just in time" fashion. b. Processes - discussions to provide relief to existing facilities will be triggered when either Party recognizes that the overall system facility (DS1s) is at 90% capacity; - both Parties will perform a joint validation to ensure current trunks have not been over- provisioned. If any trunk groups are over- provisioned, trunks will be turned down as appropriate. If any trunk resizing lowers the fill level of the system below 90%, the growth planning process will be suspended and will not be reinitiated until a 90% fill level is achieved. Trunk design blocking criteria described in Appendix ITR will be used in determining trunk group sizing requirements and forecasts; - if based on the forecasted equivalent DS1 growth, the existing fiber optic system is not projected to exhaust within one year, the Parties will suspend further relief planning on this interconnection until a date one year prior to the projected exhaust date. If growth patterns change during the suspension period, either Party may re- initiate the joint planning process; - if the placement of a minimum size FOT will not provide adequate augmentation capacity for the joint forecast over a two year period, and the forecast appears reasonable based upon history, the next larger system may be deployed. In the case of a SONET system, the OC-3 system could be upgraded to an OC-12. If the forecast does not justify a move to the next larger system, another minimal size system (such as on OC-3) could be placed. This criteria assumes both Parties have adequate fibers for either scenario. If adequate fibers do not exist, both Parties would negotiate placement of additional fibers; GENERAL TERMS AND CONDITIONS PAGE 15 OF 52 SWBT/Optel J130 - both Parties will negotiate a project service date and corresponding work schedule to construct relief facilities in an effort to achieve "just in time" deployment; - the joint planning process/negotiations should be completed within two months of identification of 90% fill. 4.3.6 Wireless Interconnection - Where the Parties agree that either Party may utilize a wireless technology, including 18 GHz, 11 GHz, 36 GHz or other microwave transmission equipment, to provide its portion of the interconnection transmission facility. Should Optel seek this interconnection method, the Parties shall mutually determine how such interconnection shall be accomplished. 4.3.7 The Parties may agree to utilize other Interconnection Methods. 4.4 PHYSICAL ARCHITECTURE. Using one or more of the Interconnection Methods described in Section 4.3 above, the Parties will agree on a physical architecture plan. This plan will be documented within Appendix DCO. The Parties agree to deploy one physical architecture plan per Metropolitan Serving Area. The two architecture arrangements, End Point Meet and Mid-Point Meet, are discussed below. Additional physical architectures, as yet undefined, may evolve during the term of this Agreement. These future as yet undefined architectures can be deployed if mutually agreed upon. 4.4.1 End Point Meet. Using the "End Point Meet" architecture, the Parties will establish transport facilities from their own Central Office(s) to the other party's Central Office(s) utilizing any method of interconnection described in Section 4.3. Unless otherwise mutually agreed upon, each Party will use its own transport facilities to provide its trunking as set forth in Appendix ITR. Each Party will be responsible for the appropriate sizing, operation, and maintenance of its own transport facilities. If initially deployed as an End Point Architecture, the deployment architecture may be migrated or groomed, upon mutual agreement, to a Mid-Point Meet architecture. 4.4.2 Mid-Point Meet. Using the Mid-Point Meet architecture, the Parties will agree upon a Network Interconnection Point (NIP). The NIP functions as a demarcation point for each Party. Each Party is responsible to transport all trunking to its side of the NIP utilizing any method of interconnection described in Section 4.3 above. Each Party is responsible for the appropriate sizing, operation, and maintenance of the transport facility and trunking to the NIP. 4.4.2.1 A second NIP can be established to eliminate a "single point of failure" when mutually agreed upon. The establishment of the second NIP should not require additional or increased trunking or facilities of either Party. Trunking from the initial NIP will be groomed or augmented to the second NIP upon mutual agreement. GENERAL TERMS AND CONDITIONS PAGE 16 OF 52 SWBT/Optel J130 4.4.2.2 When required, based on guidelines established pursuant to Appendix ITR, either Party may trunk directly to the other Party's EO. If the Party is virtually or physically collocated to the EO, then that collocation will be designated a NIP. This collocation will be used for the transport of direct EO trunking, in addition to other uses. The collocated Party is responsible for the appropriate sizing, operation, and maintenance of the transport facility. In the instance where the Party is not collocated, the EO trunk group will be handed off at the original NIP and both Parties will be responsible for the transport facility on their side of that NIP. 4.4.2.3 Unless otherwise mutually agreed upon, when Mid- Point Meet architecture has been deployed, it will remain as the architecture of choice during the term of this Agreement. 4.5 TECHNICAL SPECIFICATIONS 4.5.1 Optel and SWBT shall work cooperatively to install and maintain a reliable network. Optel and SWBT shall exchange appropriate information (e.g., maintenance contact numbers, network information, information required to comply with law enforcement and other security agencies of the Government and such other information as the Parties shall mutually agree) to achieve this desired reliability. 4.5.2 Optel and SWBT shall work cooperatively to apply sound network management principles by invoking network management controls to alleviate or to prevent congestion. 4.5.3 Technical Publications that describes the practices, procedures, specifications and interfaces generally utilized by SWBT, are listed in Appendix TP attached hereto. Appendix TP will assist the Parties in meeting their respective Interconnection responsibilities. Copies of the publications listed in Appendix TP have been or shall be provided to Optel by SWBT. 4.6 INTERCONNECTION IN ADDITIONAL METROPOLITAN EXCHANGE AREAS 4.6.1 If Optel decides to offer Telephone Exchange Services in any other Metropolitan Exchange Areas in which SWBT also offers Telephone Exchange Services, Optel shall provide written notice to SWBT of the need to establish Interconnection in such Metropolitan Exchange Areas pursuant to this Agreement. 4.6.2 The notice provided in Section 4.6.1 shall include: (i) the initial Routing Point Optel has designated in the Metropolitan Exchange Area; (ii) Optel's requested Interconnection Activation Date; and (iii) a non-binding forecast of Optel's trunking requirements. 4.6.3 Unless otherwise agreed by the Parties, the Parties shall designate the Wire Center that Optel has identified as its initial Routing Point in the Metropolitan Exchange Area as Optel Interconnection Wire Center ("IWC") in that Metropolitan Exchange Area and shall designate the SWBT Tandem Office Wire Center within the Metropolitan Exchange Area nearest to the IWC GENERAL TERMS AND CONDITIONS PAGE 17 OF 52 SWBT/Optel J130 (as measured in airline miles utilizing the V&H coordinates method) as the SWBT Interconnection Wire Center (SIWC) in that Metropolitan Exchange Area. 4.6.4 Unless otherwise agreed by the Parties, the Interconnection Activation Date in each new Metropolitan Exchange Area shall be as soon as reasonably possible, but no later than the one-hundred and fiftieth (150th) day following the date on which Optel delivered notice to SWBT of the need to establish Interconnection pursuant to Section 4.6.1. Within ten (10) business days of SWBT's receipt of Optel's notice, SWBT and Optel shall confirm their respective Wire Centers to be Interconnected and the Interconnection Activation Date for the new Metropolitan Exchange Area by attaching a supplementary schedule to Appendix DCO. 5.0 TRANSMISSION AND ROUTING OF TELEPHONE EXCHANGE SERVICE TRAFFIC PURSUANT TO SECTION 251(C)(2) 5.1 SCOPE OF TRAFFIC This Section 5.0 prescribes parameters for Traffic Exchange trunk groups the Parties shall establish over the Interconnections specified in Section 4.0. The Parties shall employ the Traffic Exchange trunk groups specified in this Section 5.0 and in Appendix ITR for the transmission and routing of traffic between the Parties' respective end users. 5.1.1 For purposes of compensation under this Agreement, the telecommunications traffic traded between Optel and SWBT will be classified as either Local Traffic, Transit Traffic, Optional Calling Area Traffic, IntraLATA Interexchange Traffic, InterLATA Interexchange Traffic, or FGA Traffic. The compensation arrangement for the joint provision of Feature Group A (FGA) Services is covered in Appendix FGA, attached hereto and incorporated herein by reference. The Parties agree that, notwithstanding the classification of traffic under this Agreement, either Party is free to define its own "local" calling area(s) for purposes of its provision of Telecommunications Services to its end users. 5.1.2 Calls originated by one Party's end user and terminated to the other Party's end user will be classified as "Local Traffic" under this Agreement if the call: (i) originates and terminates in the same SWBT exchange area; or (ii) originates and terminates within different SWBT Exchanges that share a common mandatory local calling area, e.g., mandatory Extended Area Service (EAS), mandatory Extended Local Calling Service (ELCS), or other like types of mandatory expanded local calling scopes. In no event shall the area in which the Parties exchange Local Traffic be reduced in geographic scope during the term of this Agreement. 5.2 RESPONSIBILITIES OF THE PARTIES 5.2.1 Each Party to this Agreement will be responsible for the accuracy and quality of its data as submitted to the respective Parties involved. GENERAL TERMS AND CONDITIONS PAGE 18 OF 52 SWBT/Optel J130 5.2.2 Each Party will include in the information transmitted to the other for each call being terminated on the other's network (where available), the originating Calling Party Number (CPN). 5.2.3 If the percentage of calls passed with CPN is greater than ninety percent (90%), all calls exchanged without CPN information will be billed as either local traffic or intraLATA interexchange traffic in direct proportion to the minutes of use (MOU) of calls exchanged with CPN information. If the percentage of calls passed with CPN is less than ninety percent (90%), all calls passed without CPN will be billed as if the traffic were intraLATA interexchange traffic. 5.2.4 The type of originating calling number transmitted depends on the protocol of the trunk signaling used for interconnection. Traditional toll protocol will be used with Multi-Frequency (MF) signaling, and ANI will be sent from the originating Party's end office switch to the terminating Party's tandem or end office switch. 5.2.5 Where one Party is passing CPN but the other party is not properly receiving information, the Parties will cooperate to rate the traffic correctly. 5.3 RECIPROCAL COMPENSATION FOR TERMINATION OF LOCAL TRAFFIC 5.3.1 The Compensation set forth below will apply to all Local Traffic as defined in Section 5.1.2 of this Agreement on an interim basis as provided in Section 30.18. 5.3.2 Applicability of Rates i) The rates, terms, conditions in this Section 5.3 apply only to the termination of Local Traffic, except as explicitly noted. ii) The Parties agree to compensate each other for the termination of Local Traffic on a minute of use (MOU) basis. 5.3.3 RATE ELEMENTS 5.3.3.1 A Tandem Served rate element is applicable to Tandem Routed Local Traffic on a terminating local MOU basis and includes compensation for the following sub-elements. i) Tandem Switching - compensation for the use of tandem switching functions. ii) Tandem Transport - compensation for the transmission facilities between the local tandem and the end offices subtending that tandem. iii) End Office Switching - compensation for the local EO GENERAL TERMS AND CONDITIONS PAGE 19 OF 52 SWBT/Optel J130 office switching and line termination functions necessary to complete the transmission. 5.3.3.2 An End Office Served rate element applies to direct-routed Local Traffic on a terminating local MOU basis and includes compensation for End Office Switching. This includes direct-routed Local Traffic that terminates to offices that have combined tandem and End Office functions. 5.3.4 LOCAL TRAFFIC INTERCONNECTION RATES PRICES TANDEM SWITCHING $.002453* / MOU* TANDEM TRANSPORT $.000474* / MOU (ZONES A OR B) $.000693* (ZONE C) END OFFICE SWITCHING $.002903* / MOU ZONE A SWBT RATE GROUPS 7,8/1/ ZONE B SWBT RATE GROUPS 4,5,6/1/ ZONE C SWBT RATE GROUPS 1,2,3/1/ * Interim rates in accordance with Section 30.18. The applicable Tandem rate shall be determined by the Zone in which the terminating company end office is located. THE APPLICABLE TANDEM TRANSPORT RATES SHALL BE DETERMINED BY THE ZONE IN WHICH THE TERMINATING END OFFICE IS LOCATED. 5.3.4.1 Bill and Keep will be the reciprocal compensation arrangement for the first nine (9) months after the date upon which the first commercial call is terminated between SWBT and Optel in Texas. The reciprocal compensation rates as adopted herein apply to calls that originate and terminate within the mandatory single or multiexchange local calling area of SWBT including the mandatory EAS areas served by SWBT. Bill and Keep applies only to Local Traffic and does not include Transit nor Optional Calling Area Traffic. 5.4 RECIPROCAL COMPENSATION FOR TRANSIT TRAFFIC 5.4. Transit Traffic allows one Party to send traffic to a third party network through the other Party's tandem. A Transit Traffic rate element applies to all traffic between a Party and a _________________ /1/ These rate groups are the ones identified in SWBT's General Exchange Tariff. GENERAL TERMS AND CONDITIONS PAGE 20 OF 52 SWBT/Optel J130 third party network that transits the other Party's tandem switch and fits the circumstances described in subparagraphs (i) or (ii). The originating Party is responsible for payment of the appropriate rates unless otherwise specified. The Transit Traffic rate element is only applicable when calls do not originate with (or terminate to) the transit Party's end user. The two categories of Transit Traffic are i) Local, and ii) Optional Area. The following details when each element applies: i) The Local Transit Traffic rate element applies when both the originating and terminating end users are within SWBT local and mandatory exchanges. ii) The Optional Area Transit Traffic rate element applies when one end user is in a SWBT optional exchange which is listed in Appendix Map and the other end user is within the SWBT local or mandatory exchanges. The Parties agree also to apply the Optional Area Transit rate to traffic terminating to end users in third party LECs exchange areas that share a common mandatory local calling area with all SWBT exchanges included in a specific metropolitan exchange area. ILEC mandatory exchanges are listed in Appendix Map. 5.4.1.1 The Parties acknowledge that traffic originated in third party incumbent LEC mandatory exchange areas as listed in Appendix Map may traverse the SWBT tandem and terminate in other third party LEC mandatory exchange areas. Although direct connections could be used for this traffic, SWBT agrees to transit this traffic for the rate of $O.006 per MOU if the other LEC exchanges share a common mandatory local calling area with all SWBT exchanges included in a specific exchange area. -------------------------------------------- Type of Transit Traffic Prices Per MOU -------------------------------------------- Local Transit $O.0031* -------------------------------------------- Optional Area Transit $O.0040 -------------------------------------------- 5.4.2 All other traffic which transits a tandem shall be compensated in accordance with paragraphs 5.5, 5.6 or 7.3. 5.4.3 Each Party represents that it shall not send Local Traffic to the other Party that is destined for the network of a third party unless and until such Party has the authority to exchange traffic with the third party. * Interim in accordance with Section 30.18. This rate is composed of Tandem Transport added to Zone C End Office Switching rounded to the nearest one thousandth of a dollar. GENERAL TERMS AND CONDITIONS PAGE 21 OF 52 SWBT/Optel J130 5.5 RECIPROCAL COMPENSATION FOR TERMINATION OF INTRALATA INTEREXCHANGE TRAFFIC 5.5.1 Optional Calling Area Compensation (OCA) - For the SWBT optional calling areas listed in Appendix Map, the compensation for termination of intercompany traffic will be at a rate of $0.0183 per MOU. This terminating compensation rate applies to all traffic to and from the exchange(s) listed in Appendix Map, attached hereto and incorporated by reference, and the associated metropolitan area and is independent of any retail service arrangement established by either Optel or SWBT. When cost based interconnection rates for EAS are established by the Commission in Docket 16226 (cost phase of mega- arbitration), Optel traffic in SWBT's EAS areas shall be subject to the lesser of the cost-based interconnection rates in such proceeding or the interconnection rates in effect between SWBT and other incumbent LECs for such traffic. 5.5.2 SWB also agrees to apply the OCA compensation rate of $0.0183 per MOU for traffic terminating to Optel end users in other incumbent LEC exchanges that share a common mandatory local calling area with all SWBT exchanges that are included in the metropolitan exchange area. Appendix Map lists the shared mandatory local calling areas. 5.5.3 For intrastate intraLATA interexchange service traffic, compensation for termination of intercompany traffic will be at terminating access rates for Message Telephone Service (MTS) and originating access rates for 800 Service, including the Carrier Common Line (CCL) charge, as set forth in each party's Intrastate Access Service Tariff. For interstate intraLATA intercompany service traffic, compensation for termination of intercompany traffic will be at terminating access rates for MTS and originating access rates for 800 Service including the CCL charge, as set forth in each Party's interstate Access Service Tariff. 5.6 COMPENSATION FOR ORIGINATION AND TERMINATION OF SWITCHED ACCESS SERVICE TRAFFIC TO OR FROM AN IXC (MEET-POINT BILLING (MPB) ARRANGEMENTS) 5.6.1 For interstate, interLATA traffic, terminating compensation will be at access rates as set forth in each Party's own applicable access tariffs. 5.6.2 The Parties will establish MPB arrangements in order to provide Switched Access Services to IXCs via SWBT's access tandem switch in accordance with the MPB guidelines adopted by and contained in the Ordering and Billing Forum's MECOD and MECAB documents. Optel's Meet Points with SWBT shall be those identified in Appendix DCO and any supplements thereto. 5.6.3 Billing to IXCs for the Switched Exchange Access Services jointly provided by the Parties via Meet-Point Billing arrangement shall be according to the multiple bill/single tariff method. As described in the MECAB document, each Party will render a bill in accordance with its own tariff for that portion of the service it provides. For the purpose of this Agreement, Optel is the Initial Billing Company (IBC) and SWBT is the Subsequent Billing Company (SBC). The assignment of revenues, by rate element, and the Meet-Point Billing percentages applicable to this GENERAL TERMS AND CONDITIONS PAGE 22 OF 52 SWBT/Optel J130 Agreement are set forth in the Meet Point Billing Arrangement Revenue Assignment Schedule. The actual rate values for each element shall be the rates contained in that Party's own applicable access tariffs. 5.6.4 The Parties will maintain provisions in their respective federal and state access tariffs, or provisions within the National Exchange Carrier Association (NECA) Tariff No. 4, or any successor tariff, sufficient to reflect this MPB arrangement, including MPB percentages. 5.6.5 As detailed in the MECAB document, the Parties will, in accordance with accepted time intervals, exchange all information necessary to accurately, reliably and promptly bill third Parties for Switched Access Services traffic jointly handled by the Parties via the Meet Point Arrangement. Each Party reserves the right to charge the other Party for the recording/processing functions it performs pursuant to the terms and conditions of Appendix Recording attached hereto and incorporated by reference. Information shall be exchanged in Exchange Message Record (EMR) format, on magnetic tape or via a mutually acceptable electronic file transfer protocol. 5.6.6 Initially, billing to IXCs for the Switched Access Services jointly provided by the parties via the MPB arrangement will be according to the multiple bill single tariff method, as described in the MECAB document. Each Party will render a bill to the IXC in accordance with its own tariff for that portion of the service it provides. Each Party will bill its own network access service rates to the IXC. The residual interconnection charge (RIC), if any, will be billed by the Party providing the End Office function. 5.6.7 Meet-Point Billing shall also apply to all jointly provided MOU traffic bearing the 900, 800, and 888 NPAs or any other non-geographic NPAs which may likewise be designated for such traffic in the future where the responsible party is an IXC. When SWBT performs 800 database queries, SWBT will charge the provider of the Signaling Service Point for the database query in accordance with standard industry practices. 5.6.8 Each Party shall coordinate and exchange the billing account reference ("BAR") and billing account cross reference ("BACR") numbers for the Meet Point Billing service. Each Party shall notify the other if the level of billing or other BAR/BACR elements change, resulting in a new BAI/BACR number. 5.6.9 Each Party will provide the other with the Exchange Access detailed usage data within thirty (30) days of the end of the billing period. SWBT will perform assembly and editing, messages processing and provision of Access Usage Records in accordance with Appendix Recording. Each Party will provide to the other the Exchange Access summary usage data within ten (10) working days after the date that a bill is rendered to the IXC by the initial Party. To the extent Optel provides SWBT with Access Usage Records, SWBT will compensate Optel on the same terms as Optel compensates SWBT per Appendix Recording. SWBT acknowledges that currently there is no charge for Summary Usage Data Records but that such a charge may be appropriate. At Optel's request, SWBT will negotiate a mutual and reciprocal charge for provision of Summary Usage Data Records. GENERAL TERMS AND CONDITIONS PAGE 23 OF 52 SWBT/Optel J130 5.6.10 Errors may be discovered by Optel, the IXC or SWBT. Both SWBT and Optel agree to provide the other Party with notification of any discovered errors within two (2) business days of the discovery. 5.6.11 In the event of a loss of data, both Parties shall cooperate to reconstruct the lost data within sixty (60) days of notification and if such reconstruction is not possible, shall accept a reasonable estimate of the lost data, based upon no more than three (3) to twelve (12) months of prior usage data, if available. 5.7 BILLING ARRANGEMENTS FOR COMPENSATION FOR TERMINATION OF INTRALATA, LOCAL, TRANSIT, AND OPTIONAL CALLING AREA TRAFFIC 5.7.1 Other than for traffic described in Section 5.6 above, each Party shall deliver monthly settlement statements for terminating the other Party's traffic based on the following: 5.7.1.1 Each Party shall, unless otherwise agreed, adhere to the detailed technical descriptions and requirements for the recording, record exchange, and billing of traffic using the guidelines as set forth in the Technical Exhibit Settlement Procedures (TESP), previously provided by SWBT to Optel. Reference to this technical publication is included in Appendix TP. (a) Where Optel has direct/high usage trunks to a SWBT end office with overflow trunking through a SWBT tandem, billing for the Tandem Traffic will be calculated as follows: Total Originating MOUs Recorded By Optel Less Direct ----------- End Office Terminating MOUs Recorded By SWBT Equals -------------------------------------------- Total MOUs To Be Compensated As Tandem Traffic; (b) Where Optel has direct/high usage trunks to a third party with overflow trunking through a SWBT tandem, Optel must differentiate the originating MOU records for the Parties to ascertain how many MOUs should be compensated as Transit Traffic. If Optel is unable to so differentiate the originating MOU records, the Parties shall mutually agree upon a surrogate method for calculating Transit Traffic charges owed to SWBT. 5.7.1.2 On a monthly basis, each Party will record its originating MOU including identification of the originating and terminating NXX for all intercompany calls. 5.7.1.3 Each Party will transmit the summarized originating MOU from Section 5.7.1.1 above to the transiting and/or terminating Party for subsequent monthly intercompany settlement billing. GENERAL TERMS AND CONDITIONS PAGE 24 OF 52 SWBT/Optel J130 5.7.1.4 Bills rendered by either Party will be paid within thirty (30) days of receipt subject to subsequent audit verification. 5.7.1.5 MOUs for the rates contained herein will be measured in seconds by call type, and accumulated each billing period into one (1) minute increments for billing purposes in accordance with industry rounding standards. 5.7.1.6 Each Party will multiply the tandem routed and end office routed terminating MOUs by the appropriate rate contained in this Section to determine the total monthly billing to each Party. 5.8 COMPENSATION FOR "PORTING" OPTIONAL CALLING AREA NUMBERS In those instances where an Optel end user is using a SWBT Optional Calling Area telephone number which SWBT is "porting" to Optel, Optel will compensate SWBT $6.25 monthly, per ported number. To the extent that Optel should create premium NXX's by assigning such NXXs exclusively to an optional two-way expanded local calling scope authorized or approved by the Commission (to the extent such authorization or approval is required), this compensation arrangement shall be reciprocal. 6.0 TRANSMISSION AND ROUTING OF EXCHANGE ACCESS TRAFFIC PURSUANT TO 251(C)(2) 6.1 SCOPE OF TRAFFIC Section 6.0 prescribes parameters for certain trunk groups ("Access Toll Connecting Trunks") to be established over the Interconnections specified in Section 4.0 for the transmission and routing of Exchange Access traffic between Optel Telephone Exchange Service end users and IXCs via a SWBT access tandem. 6.2 TRUNK GROUP ARCHITECTURE AND TRAFFIC ROUTING 6.2.1 The Parties shall jointly establish Access Toll Connecting Trunks as described in Appendix ITR, by which they will jointly provide tandem- transported Switched Exchange Access Services to IXCs connected to SWBT's access tandems, to enable Optel's end users to originate and terminate traffic to and from such IXCs. Nothing in this Section 6, however, shall be construed to require Optel to route all of its end users' IXC carried traffic through SWBT. 6.2.2 Access Toll Connecting Trunks shall be used solely for the transmission and routing of Switched Exchange Access to allow Optel end users to originate and terminate traffic to/from any IXC which is connected to a SWBT Access Tandem. In addition, the trunks shall be used to allow Optel's end users to connect to, or be connected to, the 800 Services of any Telecommunications Carrier connected to the SWBT Access Tandem. GENERAL TERMS AND CONDITIONS PAGE 25 OF 52 SWBT/Optel J130 7.0 TRANSPORT AND TERMINATION OF OTHER TYPES OF TRAFFIC 7.1 INFORMATION SERVICES TRAFFIC 7.1.1 At such time as the Parties agree to route intraLATA Information Services Traffic (i.e., 900 and 976 traffic) to one another, they shall agree to exchange rating and billing information to effectively allow the Parties to bill their end users and to charge reciprocal rates. 7.2 LINE STATUS VERIFICATION (LSV)/BUSY LINE INTERRUPT (BLI) TRAFFIC 7.2.1 Each Party's operator bureau shall accept LSV and BLI inquiries from the operator bureau of the other Party in order to allow transparent provision of LSV/BLI Traffic between the Parties' networks. Only one LSV attempt will be made per end user operator bureau call, and the applicable charge shall apply whether or not the line is busy at the time of verification or if the called party agrees to release the line. Only one BLI attempt will be made per end user operator telephone call, and the applicable charge shall apply whether or not the line is in use at the time of interrupt or the called party releases the line. 7.2.2 Each Party shall route LSV/BLI Traffic inquiries between the Parties' respective operator bureaus over trunks described in Appendix ITR. 7.2.3 Each Party shall compensate the other Party for LSV/BLI Traffic as set forth in Appendix Price attached hereto and incorporated by reference. 7.3 WIRELESS TRAFFIC 7.3.1 Appendix Wireless, attached hereto and incorporated by reference sets forth the terms and conditions under which the Parties will distribute revenue from their joint provision of Wireless Interconnection Service for mobile to landline traffic terminating through the Parties' respective wireline switching networks within a LATA. Appendix Wireless, however, applies only to the division of revenue received pursuant to SWBT's currently existing Wireless Interconnection Tariff. If one Party enters into an interconnection agreement with a CMRS provider, Appendix Wireless shall no longer be applicable between the Parties with respect to traffic involving such CMRS provider, and the other Party shall make arrangements with such CMRS provider as it deems appropriate for the termination of that CMRS provider's traffic. Similarly, should SWBT substantively change its existing Wireless Interconnection Tariff, or should Optel adopt a generally applicable Wireless Interconnection Tariff, the parties agree to re-establish appropriate means for the division of revenue, if any, under the new or changed tariff. 7.3.2 InterMTA traffic shall be handled in accordance with Section 5.6. 7.3.2.1 Optel shall pay the Local Transit Traffic rate to SWBT for calls that originate on Optel's network and are sent to SWBT for termination to a CMRS Provider's network. GENERAL TERMS AND CONDITIONS PAGE 26 OF 52 SWBT/Optel J130 SWBT shall pay the Local Transit Traffic rate to Optel for calls that originate on SWBT's network and are sent through Optel for termination on a CMRS Provider's network. With respect to traffic not covered by either Party's Wireless Interconnection Tariff, each Party shall be responsible for interconnection agreements with CMRS providers for terminating compensation regarding traffic originating on the Party's network and terminating on the CMRS provider's network. The originating Party shall be solely responsible for the payment of terminating compensation, if any, to the CMRS provider (when the call terminates to a third party). 7.3.3 All InterMTA traffic which transits a tandem shall be treated as intraLATA traffic as described in Section 5.5.3 or as Meet-Point Billing Traffic as described in Section 5.6 below, unless otherwise agreed. 8.0 SIGNALING 8.1 The SWBT signaling publications that describe the practices, procedures and specifications generally utilized by SWBT for signaling purposes and are listed in Appendix TP which is attached hereto and incorporated herein. A copy of these publications have been provided to Optel. 8.2 The Parties will cooperate on the exchange of Transactional Capabilities Application Part (TCAP) messages to facilitate interoperability of CCS-based features between their respective networks, including all CLASS features and functions, to the extent each Party offers such features and functions to its end users. All CCS signaling parameters will be provided including, without limitation, calling party number (CPN), originating line information (OLI), calling party category and charge number. 9.0 NUMBERING 9.1 Nothing in this Agreement shall be construed to limit or otherwise adversely impact in any manner either Party's right to employ or to request and be assigned any North American numbering Plan (NANP) number resources including, but not limited to, central office (NXX) codes pursuant to the Central Office Code Assignment Guidelines/2/, or to establish, by tariff or otherwise, Exchanges and Rating Points corresponding to such NXX codes. Each Party is responsible for administering the NXX codes it is assigned. ___________________ /2/ Last published by the Industry Numbering Committee ("INC") as INC 95-0407-008, Revision 4/7/95, formerly ICCF 93-0729-010. GENERAL TERMS AND CONDITIONS PAGE 27 OF 52 SWBT/Optel J130 9.2 At a minimum, in those Metropolitan Exchange Areas where Optel intends to provide local exchange service, Optel shall obtain a separate NXX code for each SWBT exchange or group of exchanges that share a common mandatory calling scope as defined in SWBT tariffs. This will enable Optel and SWBT to identify the jurisdictional nature of traffic for intercompany compensation until such time as both Parties have implemented billing and routing capabilities to determine traffic jurisdiction on a basis other than NXX codes. 9.3 Each Party agrees to make available to the other, up-to-date listings of its own assigned NPA-NXX codes, along with associated Rating Points and Exchanges. 9.4 To the extent SWBT serves as Central Office Code Administrator for a given region, SWBT commits to treat Optel requests for assignment of central office code(s) in a neutral and nondiscriminatory manner, consistent with regulatory requirements, and (NXX) Central Office Code Assignment Guidelines. 9.5 Each Party is responsible to program and update its own switches and network systems to recognize and route traffic to the other Party's assigned NXX codes at all times. Neither Party shall impose fees or charges on the other Party for such required programming and updating activities. 9.6 Each Party is responsible to input required data into the Routing Data Base Systems (RDBS) and into the Bellcore Rating Administrative Data Systems (BRADS) or other appropriate system(s) necessary to update the Local Exchange Routing Guide (LERG), unless negotiated otherwise. 9.7 Neither Party is responsible for notifying the other Parties' end users of any changes in dialing arrangements, including those due to NPA exhaust, unless otherwise ordered by the Commission, the FCC, or a court. 9.8 NXX MIGRATION. Where either Party has activated an entire NXX for a single end user, or activated more than half of an NXX for a single end user with the remaining numbers in that NXX either reserved for future use or otherwise unused, if such end user chooses to receive service from the other Party, the first Party shall cooperate with the second Party to have the entire NXX reassigned in the LERG (and associated industry databases, routing tables, etc.) to an End Office operated by the second Party. Such transfer will require development of a transition process to minimize impact on the Network and on the end user(s)' service and will be subject to appropriate industry lead times (currently forty-five (45) days) for movements of NXXs from one switch to another. The Party to whom the NXX is migrated will pay NXX migration charges of $10,000.00 per NXX. GENERAL TERMS AND CONDITIONS PAGE 28 OF 52 SWBT/Optel J130 10.0 RESALE - SECTION 251(b)(1); 251(c)(4); 252(d)(3); and 271(c)(2)(B)(xiv); 10.1 Availability of SWBT Retail Telecommunications Services for Resale SWBT shall offer to Optel for resale at wholesale rates its Telecommunications Services, as described in Section 251(c)(4) of the Act, pursuant to the terms and conditions of Appendix Resale attached hereto and incorporated herein by this reference. 10.2 Availability of Optel Retail Telecommunication Services for Resale Optel shall make available its Telecommunications Services for resale at wholesale rates to SWBT in accordance with Section 251(b)(1) of the Act. 11.0 UNBUNDLED NETWORK ELEMENTS - SECTIONS 251(c)(3), 271(c)(2)(B) (ii),(iv), (v),(vi),(x) 11.1 SWBT shall provide Optel access to unbundled network elements for the provision of a telecommunication service as described in Section 251(c)(3) and 271(c)(2)(B) of the Act, pursuant to the terms and conditions of Appendix UNE attached hereto and incorporated herein by this reference. 11.2 Optel shall make available access to its Unbundled Network elements in accordance with Section 251(c)(3) of the Act. 12.0 NOTICE OF CHANGES - SECTION 251(c)(5) Nothing in this Agreement shall limit either Party's ability to upgrade its network through the incorporation of new equipment, new software or otherwise. If a Party makes a change in its network which it believes will materially affect the interoperability of its network with the other Party, the Party making the change shall provide at least ninety (90) days advance written notice of such change to the other Party. Notwithstanding the foregoing, if either Party establishes additional tandems in an exchange area in which the other Party offers local exchange service, that Party will provide the other Party with not less than one-hundred eighty (180) days' advance notification of same, and with greater notification when practicable. Both Parties agree to coordinate interconnection matters consistent with the requirements of the Americans with Disabilities Act (42 U.S.C. 12101) and with Sections 255 and 256 of the Act. In addition, the Parties will comply with the Network Disclosure rules adopted by the FCC in CC Docket No. 96-98, Second Report and Order, as may be amended from time to time. The Party upgrading its network shall be solely responsible for the cost and effort of accommodating such changes in its own network.

Neither Party shall use the other Party's Proprietary Information for any other purpose except upon such terms and conditions as may be agreed upon between the Parties in writing. 30.6.4 Unless otherwise agreed, the obligations of confidentiality and nonuse set forth in the Agreement do not apply to such Proprietary Information that: (a) was at the time of receipt, already known to the Receiving Party, free of any obligation to keep confidential and evidenced by written records prepared prior to delivery by the Disclosing Party; (b) is, or becomes publicly known through no wrongful act of the receiving Party; (c) is rightfully received from a third person having no direct or indirect secrecy or confidentiality obligation to the Disclosing Party with respect to such information; (d) is independently developed by an employee, agent, or contractor of the Receiving Party which individual is not involved in any manner with the provision of services pursuant to the Agreement and does not have any direct or indirect access to the Proprietary Information; GENERAL TERMS AND CONDITIONS PAGE 43 OF 52 SWBT/Optel J130 (e) is disclosed to a third person by the Disclosing Party without similar restrictions on such third person's rights; (f) is approved for release by written authorization of the Disclosing Party (g) is required to be made public by the Receiving Party pursuant to applicable law or regulation provided that the Receiving party shall provide the Disclosing Party with written notice of such requirement as soon as possible and prior to such disclosure.

The Receiving Party shall use all commercially reasonable efforts to cooperate with the Disclosing Party in attempting to obtain any protective relief which such Disclosing Party chooses to obtain. Notwithstanding the foregoing, SWBT shall be entitled to disclose confidential information on a confidential basis to regulatory agencies upon request for information as to SWBT's activities under the Act. 30.6.5 Notwithstanding any other provision of this Agreement, the Proprietary Information provisions of this Agreement shall apply to all information furnished by either Party to the other in furtherance of the purpose of this Agreement, even if furnished before the date of this Agreement. 30.6.6 Pursuant to Section 222(b) of the Act, both parties agree to limit their use of Proprietary Information received from the other to the permitted purposed identified in the Act. 30.7 GOVERNING LAW. For all claims under this Agreement that are based upon issues within the jurisdiction (primary or otherwise) of the FCC, the exclusive jurisdiction and remedy for all such claims shall be as provided for by the FCC and the Act. For all claims under this Agreement that are based upon issues within the jurisdiction (primary or otherwise) of the Commission, the exclusive jurisdiction for all such claims shall be with such Commission, and the exclusive remedy for such claims shall be as provided for by such Commission. In all other respects, this Agreement shall be governed by the domestic laws of Texas without reference to conflict of law provisions. 30.8 TAXES. 30.8.1 Each Party purchasing services hereunder shall pay or otherwise be responsible for all federal, state, or local sales, use, excise, gross receipts, transaction or similar taxes, fees, or surcharges (hereinafter "Tax") levied against or upon such purchasing party (or the providing Party when such providing Party is permitted by applicable law to pass along to the purchasing party such taxes, fees, or surcharges), except for any Tax on either party's corporate existence, status, or income. Whenever possible, these amounts shall be billed as a separate item on the invoice. To the extent a sale is claimed to be for resale tax exemption, the purchasing GENERAL TERMS AND CONDITIONS PAGE 44 OF 52 SWBT/Optel J130 party shall furnish the providing party a proper resale tax exemption certificate as authorized or required by statute or regulation by the jurisdiction providing said resale tax exemption. Failure to timely provide said resale tax exemption certificate will result in no exemption being available to the purchasing Party until such time as the purchasing Party presents a valid certification. Failure to timely provide said resale tax exemption certificate will result in no exemption being available to the purchasing Party until such time as the purchasing Party presents a valid certificate. 30.8.2 With respect to any purchase of services, facilities or other arrangements, if any Tax is required or permitted by applicable law to be collected from the purchasing party by the providing party, then (i) the providing party shall bill the purchasing party for such Tax, (ii) the purchasing party shall remit such Tax to the providing party and (iii) the providing party shall remit such collected Tax to the applicable taxing authority. 30.8.3 With respect to any purchase hereunder of services, facilities or arrangements that are resold to a third party, if any Tax is imposed by applicable law on the end user in connection with any such purchase, then (i) the purchasing party shall be required to impose and/or collect such Tax from the end user and (ii) the purchasing party shall remit such Tax to the applicable taxing authority. The purchasing party agrees to indemnify and hold harmless the providing party on an after-tax basis for any costs incurred by the providing party as a result of actions taken by the applicable taxing authority to collect the Tax from the providing party due to the failure of the purchasing party to pay or collect and remit such tax to such authority. 30.8.4 If the providing party fails to collect any Tax as required herein, then, as between the providing party and the purchasing party, (i) the purchasing party shall remain liable for such uncollected Tax and (ii) the providing party shall be liable for any penalty and interest assessed with respect to such uncollected Tax by such authority. However, if the purchasing party fails to pay any taxes properly billed, then, as between the providing party and the purchasing party, the purchasing party will be solely responsible for payment of the taxes, penalty and interest. 30.8.5 If the purchasing party fails to impose and/or collect any Tax from end users as required herein, then, as between the providing party and the purchasing party, the purchasing party shall remain liable for such uncollected Tax and any interest and penalty assessed thereon with respect to the uncollected Tax by the applicable taxing authority. With respect to any Tax that the purchasing party has agreed to pay or impose on and/or collect from end users, the purchasing party agrees to indemnify and hold harmless the providing party on an after-tax basis for any costs incurred by the providing party as a result of actions taken by the applicable taxing authority to collect the Tax from the providing Party due to the failure of the purchasing party to pay or collect and remit such Tax to such authority. 30.9 NON-ASSIGNMENT. This Agreement shall be binding upon every subsidiary and Affiliate of either Party that is engaged in providing Telephone Exchange and Exchange Access GENERAL TERMS AND CONDITIONS PAGE 45 OF 52 SWBT/Optel J130 services in any territory within which SWBT is an Incumbent Local Exchange Carrier as of the date of this Agreement (the "SWBT Territory") and shall continue to be binding upon all such entities regardless of any subsequent change in their ownership. Each Party covenants that, if it sells or otherwise transfers to a third party its Telephone Exchange and Exchange Access network facilities within the SWBT Territory, or any portion thereof, to a third party, it will require as a condition of such transfer that the transferee agree to be bound by this Agreement with respect to services provided over the transferred facilities. Except as provided in this paragraph, neither Party may assign or transfer (whether by operation of law or otherwise) this Agreement (or any rights or obligations hereunder) to a third party without the prior written consent of the other Party; provided that each Party may assign this Agreement to a corporate Affiliate or an entity under its common control or an entity acquiring all or substantially all of its assets or equity by providing prompt written notice to the other Party of such assignment or transfer. Any attempted assignment or transfer that is not permitted is void ab initio. Without limiting the generality of the foregoing, this Agreement shall be binding upon and shall inure to the benefit of the Parties' respective successors and assigns. 30.10 NON-WAIVER. Failure of either Party to insist on performance of any term or condition of this Agreement or to exercise any right or privilege hereunder shall not be construed as a continuing or future waiver of such term, condition, right or privilege. 30.11 AUDITS. Each Party to this Agreement will be responsible for the accuracy and quality of its data as submitted to the respective Parties involved. 30.11.1 Upon reasonable written notice and at its own expense, each Party or its authorized representative (providing such authorized representative does not have a conflict of interest related to other matters before one of the Parties) shall have the right to conduct an audit of the other Party to give assurances of compliance with the provisions of this Agreement; provided, that neither Party may request more than two (2) such audits within any twelve (12) month period. This includes on-site audits at the other Party's or the Party's vendor locations.

Under this Section 30 12, if any portion of an amount due to a Party (the "Billing Party") under this Agreement is subject to a bona fide dispute between the Parties, the Party billed (the "Non-Paying Party") shall within sixty (60) days of its receipt of the invoice containing such disputed amount give notice to the Billing Party of the amounts it disputes ("Disputed Amounts") and include in such notice the specific details and reasons for disputing each item. The Non-Paying Party shall pay when due: (i) all undisputed amounts to the Billing Party: and (ii) all Disputed Amounts to Billing Party. 30.12.2 If the Parties are unable to resolve the issues related to the Disputed Amounts in the normal course of business within sixty (60) days after delivery to the Billing Party of notice of the Disputed Amounts, each of the Parties shall appoint a designated representative who has authority to settle the dispute and who is at a higher level of management than the persons with direct responsibility for administration of this Agreement.

If either Party enters into an agreement (the "Other Agreement") approved by the Commission or FCC pursuant to Section 252 of the Act (regardless of whether the approved agreement was negotiated or arbitrated) which provides for the provision of arrangements covered in this Agreement to another requesting Telecommunications Carrier, including an Affiliate, such Party shall make available to the other party such arrangements upon the same rates, terms and conditions as those provided in the Other Agreement. At its sole option, the other Party may avail itself of either (i) the Other Agreement in its entirety or (ii) the prices, terms and conditions of the Other Agreement that directly relate to any of the following duties as a whole: (a) Interconnection - Section 251(c)(2) of the Act; or (b) Exchange Access - Section 251(c)(2) of the Act; or (c) Unbundling - Section 251(c)(3) of the Act; or (d) Resale - Section 251(c)(4) of the Act; or (e) Collocation - Section 251(c)(6) of the Act; or (f) Number Portability - Section 251(b)(2) of the Act; or (g) Database Access - Section 271(c)(2)(B)(x) of the Act; or (h) Access to Rights of Way - Section 251(b)(4) of the Act; or (i) Operator Services - Section 271(c)(2)(B)(vii)(III); or (j) Directory Assistance - Section 271(c)(2)(B)(vii)(II). 30.17 JOINT WORK PRODUCT.

Some rates contained in this Agreement have been derived from the mega-arbitration docket (AT&T et. al. Arbitration Docket No. 16189) and designated by the Commission as interim. Such interim rates are to be replaced by subsequent rates determined by the Commission in the cost phase of the mega-arbitration docket when such subsequent rates have been included in an arbitrated Agreement approved by the Commission in a final order. The subsequent GENERAL TERMS AND CONDITIONS PAGE 49 OF 52 SWBT/Optel J130 rates shall apply to this Agreement on a prospective basis only.

This Agreement is entered into as a result of both private negotiation between the Parties and the incorporation of some of the results of arbitration by the Public Utility Commission of Texas in Docket Nos. 16189, et al. (the Arbitration Award). If the actions of Texas or federal legislative bodies, courts, or regulatory agencies of competent jurisdiction invalidate, modify, or stay the enforcement of laws or regulations that were the basis for a provision of the contract which is reflective of the Arbitration Award approved by the Commission, the affected provision shall be invalidated, modified, or stayed, consistent with the action of the legislative body, court, or regulatory agency. In such event, the Parties shall expend diligent efforts to arrive at an agreement respecting the modifications to the Agreement. If negotiations fall, disputes between the Parties concerning the interpretation of the actions required or provisions affected by such governmental actions shall be resolved pursuant to the dispute resolution process provided for in this Agreement. The invalidation, stay, or modification of the pricing provisions of the FCC's First Report and Order in CC Docket No.96-98 (August 8, 1996) and the FCC's Order on Reconsideration (September 27, 1996) shall not be considered an invalidation, stay, or modification requiring changes to provisions of the Agreement required by the Commission Arbitration Award, in that the FCC's pricing provisions are not the basis for the costing and pricing provisions of the Commission's Arbitration Award. 30.20 NO THIRD PARTY BENEFICIARIES; DISCLAIMER OF AGENCY. This Agreement is for the sole benefit of the Parties and their permitted assigns, and nothing herein express or implied shall create or be construed to create any third-party beneficiary rights hereunder. Except for provisions herein expressly authorizing a Party to act for another, nothing in this Agreement shall constitute a Party as a legal representative or agent of the other Party, nor shall a Party have the right or authority to assume, create or incur any liability or any obligation of any kind, express or implied, against or in the name or on behalf of the other Party unless otherwise expressly permitted by such other Party. Except as otherwise expressly provided in this Agreement, no Party undertakes to perform any obligation of the other Party, whether regulatory or contractual, or to assume any responsibility for the management of the other Party's business. 30.21 NO LICENSE. No license under patents, copyrights or any other intellectual property right (other than the limited license to use consistent with the terms, conditions and restrictions of this Agreement) is granted by either Party or shall be implied or arise by estoppel with respect to any transactions contemplated under this Agreement. 30.22 SURVIVAL.
