 SUMMARY:  WORLD ACCESS, INC. AND TELCO SYSTEMS, INC. TO MERGE 
  
 FOR IMMEDIATE RELEASE 
  
 ATLANTA, GEORGIA   June 4, 1998   WORLD ACCESS, INC. (Nasdaq:  WAXS) and
 Telco Systems, Inc. (Nasdaq:  TELC) announced today that they have entered
 into a definitive agreement to merge the two companies.  The closing of the
 merger is subject to the satisfaction of customary conditions, including
 the receipt of stockholder and regulatory approvals.  The transaction is
 expected to be accounted for as a purchase and to qualify as a tax-free
 reorganization.  The combined company will retain the World Access name. 
  
 Telco Systems, based in Norwood, Massachusetts, has supplied products and
 related services to the telecommunications industry since 1972.  The
 company is well known for its asynchronous fiber optic systems and
 intelligent channel banks, with an installed base of over $1 billion. 
 Today, the company concentrates on the integrated access, high capacity
 multiplexer and Frame Relay/ATM access markets.  Telco Systems has
 established supply contracts with leading telecommunications service
 providers, including NYNEX/Bell Atlantic, GTE, British Telecom and Concert
 Communications, and has recently introduced several new products, including
 its Access45trademark and EdgeLink 100trademark.  During its latest fiscal
 year, Telco Systems generated approximately $120 million in revenues. 
  
 The merger agreement provides that each of the approximately 11 million
 shares of Telco Systems common stock will be converted into shares of World
 Access common stock having a value of $17.00 per share, based on the
 average daily closing price of World Access common stock as reported on the
 Nasdaq National Market System for a predefined period prior to the
 effective time of the merger (the "Closing Price").  If the Closing Price
 is more than $36.00, then each share of Telco Systems common stock will be
 converted into 0.4722 shares of World Access common stock.  If the Closing
 Price is less than $29.00, then each share of Telco Systems common stock
 will be converted into 0.5862 shares of World Access common stock. 
  
 The merger agreement has been unanimously approved by the Boards of
 Directors of both companies.  The Robinson-Humphrey Company, LLC is acting
 as financial advisor to World Access on this transaction and Broadview
 Associates LLC is representing Telco Systems. 
  
 The companies will be sponsoring a teleconference to review the planned
 merger on Friday, June 5, 1998, at 8:30 a.m., EDT.  To participate in this
 teleconference, interested parties should call 212-346-6404.  A taped

 Steven A. Odom, Chairman and Chief Executive Officer of World Access, said,
 "The combination of World Access and Telco Systems will strengthen our
 competitive positioning in the global telecommunications market.  The
 proprietary technology, advanced product offerings and strong customer
 relationships contributed by Telco Systems will significantly enhance our
 ability to support and service our collective customers as they build new
 and/or upgrade existing telecommunications networks.  The merger is
 expected to be consummated in the third quarter and positively impact World
 Access earnings per share for calendar year 1999." 
  
 Hensley E. West, President and Chief Operating Officer of World Access,
 added, "We are pleased that Telco's team of experienced industry
 professionals will continue to manage Telco Systems as a key division of
 World Access.  Telco Systems will become the cornerstone of our transport
 and access product areas, encompassing several other existing World Access
 divisions.  The integration of these divisions will provide a technology
 and product focus geared towards meeting the increasing demands for value-
 added network access systems.  As a result of the merger, we will provide
 our customers greater network solutions capabilities, in addition to the
 network access services that will be available as a result of the pending
 Resurgens acquisition." 
  
 Dr. William B. Smith, President and Chief Executive Officer of Telco
 Systems, said, "The strong management team we've assembled at Telco Systems
 over the past few years is excited to join forces with World Access.  We
 have concentrated on developing competitive high-speed multiplexer and
 integrated access systems employed at the edge of the network and have
 recently released several new products that are receiving excellent market
 acceptance.  We look forward to combining talents with World Access to
 offer our broad customer base a more complete network solution." 
  
 While much of Telco Systems' revenue is generated through the sale of
 equipment directly to approximately two dozen large service providers
 around the world, the company brings to World Access a solid set of
 distribution partners, including Walker and Associates, Sprint North
 Supply, GTE Supply, Alltel Supply and TelSource.  In addition, Telco
 Systems has relationships with over 40 distributors in international
 markets.  The combined portfolio of World Access and Telco Systems will
 give all of the combined company's sales channels a more complete line of
 product solutions. 
  
 Each company brings to this alliance distinct competencies that will offer
 immediately operational efficiencies, especially in the areas of
 manufacturing and customer service.  For example, World Access'
 manufacturing infrastructure includes "rack 'n stack" configuration
 capabilities that will be available for Telco Systems' products and
 customers.  With this capability, many different product configurations can
 be pre-assembled and tested for immediate shipment, offering a competitive
 advantage in the sales process.  Both companies are ISO certified, and have
 well established and documented operating procedures to assure high quality
 products and services are provided to their customers. 
  
 World Access, Inc. develops, manufactures and markets wireline and wireless
 switching, transport and access products for the global telecommunications
 markets.  The Company's products allow telecommunications service providers
 to build and upgrade their central office and outside plant networks in
 order to provide a wide array of voice, data and video services to their
 business and residential customers.  World Access offers digital switches,
 billing and network telemanagement systems, cellular base stations, fixed
 wireless local loop systems, intelligent multiplexers, microwave and
 millimeterwave radio systems and other telecommunications network products. 
 To support and complement its product sales, the Company also provides its
 customers with a broad range of design, engineering, manufacturing,
 testing, installation, repair and other value-added services.
