Summary of Significant Accounting Policies [Abstract]
Summary of Significant Accounting Policies	NOTE 1 – SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES Description of Business Communications Systems, Inc. (herein collectively referred to as “CSI,” “our,” “we” or the “Company”) is a Minnesota corporation organized in 1969 that has classified its business into two segments: (1) the Electronics & Software segment (consisting of US-based subsidiary Transition Networks and UK-based subsidiary Net2Edge) which (i) manufactures and sells solutions that provide actionable intelligence, power and connectivity at the edge of networks through PoE products, software and services as well as traditional products such as media converters, network adapters and other connectivity products and (ii) designs, develops, and sells edge network access products, TDM (time-division multiplexing) over IP and other circuit emulation solutions, along with specialized cloud-based software solutions, primarily within the telecommunications market; and (2) the Services and Support segment (consisting of subsidiaries JDL and Ecessa), which (i) provides technology solutions including virtualization, managed services, wired and wireless network design and implementation, and hybrid cloud infrastructure and deployment and (ii) designs, develops, and sells SD-WAN (software-designed wide-area network) solutions. As described in Note 16 of Notes to Financial Statements, on August 2, 2021, the Company and Lantronix, Inc. completed the sale by CSI to Lantronix of all of the issued and outstanding stock of CSI’s wholly owned subsidiary, Transition Networks, Inc., and the entire issued share capital of its wholly owned subsidiary, Transition Networks Europe Limited (collectively with Transition Networks, Inc., the “TN Companies”), pursuant to the securities purchase agreement dated April 28, 2021 (“E&S Sale Transaction”). For purposes of this Form 10-Q, the Company classifies its businesses into the two segments discussed above. Non-allocated general and administrative expenses are separately accounted for as “Other” in the Company’s segment reporting. Intersegment revenues are eliminated upon consolidation. Financial Statement Presentation The condensed consolidated balance sheet as of June 30, 2021, the related condensed consolidated statements of loss and comprehensive loss, the condensed consolidated statements of changes in stockholders’ equity for the three and six months ended June 30, 2021 and 2020, and the condensed consolidated statements of cash flows for the periods ended June 30, 2021 and 2020 have been prepared by Company management. In the opinion of management, all adjustments (which include only normal recurring adjustments, except where noted) necessary to present fairly the financial position, results of operations, and cash flows at June 30, 2021 and 2020 and for the periods then ended have been made. Certain information and footnote disclosures normally included in consolidated financial statements prepared in accordance with generally accepted accounting principles in the United States of America have been condensed or omitted. We recommend these condensed consolidated financial statements be read in conjunction with the financial statements and notes thereto included in the Company’s December 31 , 2020 Annual Report to Shareholders on Form 10-K (“2020 Form 10-K”). The results of operations for the period ended June 30, 2021 are not necessarily indicative of operating results for the entire year. The presentation of financial statements in conformity with generally accepted accounting principles requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities, and disclosure of contingent assets and liabilities at the balance sheet date, and the reported amounts of revenues and expenses during the reporting period. The estimates and assumptions used in the accompanying condensed consolidated financial statements are based upon management’s evaluation of the relevant facts and circumstances as of the time of the financial statements. Actual results could differ from those estimates. Except to the extent updated or described below, the significant accounting policies set forth in Note 1 to the consolidated financial statements in the December 31, 2020 Form 10-K, appropriately represent, in all material respects, the current status of accounting policies, and are incorporated herein by reference. Accumulated Other Comprehensive Loss The components of accumulated other comprehensive loss, net of tax, are as follows: Accumulated Other Comprehensive Loss Other Foreign Currency Unrealized gain Comprehensive Translation (loss) on securities Loss December 31, 2020 $ ( 700,000 ) $ 21,000 $ ( 679,000 ) Net current period change 56,000 ( 7,000 ) 49,000 June 30, 2021 $ ( 644,000 ) $ 14,000 $ ( 630,000 )

Revenue Recognition [Abstract]
Revenue Recognition	NOTE 2 – REVENUE RECOGNITION Electronics & Software The Company has determined that the revenue recognition for its Electronics & Software segment occurs upon delivery of the Company’s connectivity infrastructure and data transmission products. To determine when revenue should be recognized, it is important to determine when the transfer of control has occurred. The Company has determined that control transfers for these products upon shipment or delivery to the customer, in accordance with the agreed-upon shipping terms. As such, the timing of revenue recognition occurs at a specific point in time. Services & Support The Company has determined that the following performance obligations identified in its Services & Support segment are transferred over time: managed services and professional services (time and materials (“T&M”) and fixed price) as well as services under maintenance and service contracts. The managed services performance obligation is a bundled solution consisting of a series of distinct services that are substantially the same and that have the same pattern of transfer to the customer and are therefore recognized evenly over the term of the contract. T&M professional services arrangements are recognized over time with an input method based on hours expended towards satisfying the performance obligation. Fixed price professional service arrangements under a relatively longer-term service are also recognized over time with an input method based on hours expended. Maintenance and service contracts are recognized evenly over the life of the contract. The Company has also identified the following performance obligations within its Services & Support segment that are recognized at a point in time which include resale of third-party hardware and software, installation, arranging for another party to transfer services to the customer, and certain professional services. The resale of third-party hardware and software is recognized at a point in time, when the goods are shipped or delivered to the customer’s location, in accordance with the shipping terms. Installation services are recognized at a point in time when the services are completed. The service the Company provides to arrange for another party to transfer services to the customer is satisfied at a point in time after the Company has transferred control when the service is first available to the customer by the third-party vendor. The Company reports revenue from these third-party services on a net basis in its financial statements. Depending on the nature of the service, certain professional services transfer control at a point in time. The Company evaluates these circumstances on a case by case basis to determine if revenue should be recognized over time or at a point in time. Disaggregation of revenue Revenues are recognized when control of the promised goods or services is transferred to our customers, in an amount that best reflects the consideration we expect to receive in exchange for those goods or services.

Contingencies [Abstract]
Contingencies	NOTE 9 – CONTINGENCIES In the ordinary course of business, the Company is exposed to legal actions and claims and incurs costs to defend against these actions and claims. Company management is not aware of any outstanding or pending legal actions or claims that could materially affect the Company’s financial position or results of operations. On June 28, 2021, CSI entered into a securities purchase agreement with a group of institutional investors (the “PIPE Investors”) to make a $ 25.0 million private placement investment in CSI in connection with the closing of the previously announced merger transaction between CSI and Pineapple Energy, LLC (“Pineapple”). Proceeds of this investment will used primarily to fund Pineapple strategic initiatives. The closing of the financing is subject to approval of CSI’s shareholders and other customary conditions. Under the terms of the securities purchase agreement, the PIPE Investors have agreed to purchase $ 25.0 million in newly authorized CSI Series A Convertible Preferred Stock convertible at a price of $ 3.40 per share into CSI common stock, with five year warrants to purchase an additional $ 25.0 million of common shares at that same price (the “PIPE Offering”). The PIPE Offering is expected to close immediately following the consummation of the CSI-Pineapple merger transaction (the “Merger”). Therefore the PIPE Investors will invest in the post-Merger company, will not be entitled to receive any cash dividends paid prior to closing and will not receive the Contingent Value Rights (“CVRs”) to be issued to pre-Merger CSI shareholders. CSI and one of the PIPE Investors, CrowdOut Capital LLC (“CrowdOut”), which has agreed, subject to the satisfaction of certain closing conditions, to purchase $ 9.0 million of the $ 25.0 million of Series A Convertible Preferred Stock, have also entered into a non-binding letter of intent for a $ 20.0 million term loan (the “Debt Transaction”) to be provided by CrowdOut to the Company to assist the combined CSI-Pineapple company fund the acquisitions of Hawaii Energy Connection (“HEC”) and E-GEAR, which are expected to close concurrently with the Merger. CrowdOut’s obligation to consummate the transactions in the PIPE Offering, including its obligation to purchase the CSI Series A Convertible Preferred Stock and warrants from the Company, is expressly conditioned on CrowdOut closing and funding the Debt Transaction pursuant to fully executed credit documents that are mutually acceptable to CSI and CrowdOut. The Series A Convertible Preferred Stock will have no liquidation or dividend preference over CSI common stock and no voting rights until after converted into CSI common stock. Assuming conversion of the Series A Convertible Preferred Stock, the PIPE Investors would own approximately 7.35 million shares of the Company’s outstanding common stock immediately following the closing of the PIPE Offering, representing approximately 22 % of CSI’s outstanding Common Stock after giving effect to the issuance of shares in the Merger, and approximately 14.7 million shares assuming exercise of all the warrants for cash, representing approximately 37 % of CSI’s outstanding common stock after giving effect to the issuance of shares in the Merger and exercise of the warrants. The Series A Convertible Preferred Stock and warrants will have anti-dilution provisions that would increase the number of shares issuable upon conversion or exercise, and lower the conversion or exercise price, if CSI issues equity securities at a price less than the conversion or exercise price at the time of such issuance. The securities purchase agreement also prohibits the combined company from conducting a new equity offering within 30 days of the closing, gives the PIPE Investors in the aggregate the right to purchase up to 25 % of the equity securities in future CSI-Pineapple offerings within one year of closing and requires 30 -day lock-up agreements of CSI common stock by certain CSI-Pineapple officers, directors and major shareholders following the closing. In connection with the transaction, CSI has agreed to file a registration statement on behalf of the PIPE Investors allowing them to resell the common stock into which the Series A Convertible Preferred Stock is convertible and the warrants are exercisable immediately after issuance. Closing is subject to the effectiveness of this registration statement and other customary closing conditions. The foregoing descriptions of the (i) securities purchase agreement, (ii) the CSI Series A Convertible Preferred Stock, (iii) the warrant, (iv) the registration rights agreement, (v) the lock up agreement between the Company, certain CSI-Pineapple officers, directors and major shareholders and the PIPE Investors, and (vi) the letter agreement dated as of June 28, 2021 between Communications Systems, Inc. and CrowdOut Capital LLC confirming that the CrowdOut $ 9.0 million equity commitment is contingent on closing of the $ 20.0 million term loan do not purport to be complete and are qualified in their entirety by reference to the full text of these agreements, which are filed as Exhibit 10.1, 4.1, 4.2, 4.3, 10.2 and 10.3 to the Company’s Current Report on Form 8-K dated June 28, 2021 and are incorporated herein by reference.

Debt [Abstract]
Debt	NOTE 10 – DEBT Line of Credit On August 28, 2020, the Company entered into a Credit Agreement with Wells Fargo Bank, National Association, establishing a $ 5,000,000 line of credit facility agreement that replaced a prior facility. On October 29, 2020, the Company entered into a First Amendment to the Credit Agreement. Under the Credit Agreement, as amended, the Company has the ability to obtain one or more letters of credit in an aggregate amount up to $ 2,000,000 , subject to the general terms of the credit agreement. The Company had no outstanding borrowings against the line of credit, or the prior credit facility, at June 30, 2021 or December 31, 2020 and $ 2,101,000 of the credit line was available for use. Due to the revolving nature of loans under this credit facility, additional borrowings and periodic repayments and re-borrowings may be made until the maturity date. Interest on borrowings on the credit line is at LIBOR plus 1.25 %, with a minimum LIBOR rate of 0.75 %, ( 2.0 % at June 30, 2021). By its terms, the Credit Agreement was scheduled to expire on August 28, 2021 and was secured by government securities owned and pledged by the Company.

Income Taxes [Abstract]
Income Taxes	NOTE 11 – INCOME TAXES In the preparation of the Company’s consolidated financial statements, management calculates income taxes based upon the estimated effective rate applicable to operating results for the full fiscal year. This includes estimating the current tax liability as well as assessing differences resulting from different treatment of items for tax and book accounting purposes. These differences result in deferred tax assets and liabilities, which are recorded on the balance sheet. Management analyzes these assets and liabilities regularly and assesses the likelihood that deferred tax assets will be recovered from future taxable income. At June 30, 2021 there was $ 117,000 of net uncertain tax benefit positions that would reduce the effective income tax rate if recognized. The Company records interest and penalties related to income taxes as income tax expense in the condensed consolidated statements of loss and comprehensive loss. The Company is subject to U.S. federal income tax as well as income tax of multiple state and foreign jurisdictions. The tax years 2017 - 2020 remain open to examination by the Internal Revenue Service and the years 2016 - 2020 remain open to examination by various state tax departments. The tax years from 2017 - 2020 remain open in Costa Rica. The Company’s effective income tax rate was ( 0.0 %) for the first six months of 2021. The effective tax rate differs from the federal tax rate of 21 % due to state income taxes, foreign tax rate differences, foreign losses not deductible for U.S. income tax purposes, the effect of uncertain income tax positions, stock compensation windfalls and changes in valuation allowances related to deferred tax assets. The foreign operating losses may ultimately be deductible in the countries in which they occurred; however, the Company has no t recorded a deferred tax asset for these losses due to uncertainty regarding the eventual realization of the benefit. The effect of the foreign operations was an overall rate decrease of approximately 0.5 % for the six months ended June 30, 2021. There were no additional uncertain tax positions identified in the first six months of 2021. The Company's effective income tax rate for the six months ended June 30, 2020 was 0.2 %, and differed from the federal tax rate due to state income taxes, foreign tax rate differences, foreign losses not deductible for U.S. income tax purposes, changes in the reserve for uncertain income tax positions, provisions for interest charges for uncertain income tax positions, stock compensation windfalls and changes in valuation allowances related to deferred tax assets.

Segment Information [Abstract]
Segment Information	NOTE 12 – SEGMENT INFORMATION The Company classifies its businesses into two segments as follows:  Electronics & Software: designs, develops and sells Intelligent Edge solutions that provide connectivity and power through PoE products and actionable intelligence to end devices in an IoT ecosystem through embedded and cloud-based management software. In addition, this segment continues to generate revenue from its traditional products consisting of media converters, NICs, and Ethernet switches that offer the ability to affordably integrate the benefits of fiber optics into any data network; and  Services & Support: provides technology solutions that address prevalent IT challenges, including network resiliency, security products and services, network virtualization, and cloud migrations, IT managed services, wired and wireless network design and implementation, and converged infrastructure configuration, deployment and management . Management has chosen to organize the Company and disclose reportable segments based on our products and services. Intersegment revenues are eliminated upon consolidation. “Other” includes non-allocated corporate overhead costs. As a result of our treatment of Suttle as discontinued operations, “Other” includes amounts previously allocated to Suttle that do not meet the criteria to be included in income from discontinued operations. Information concerning the Company’s continuing operations in these two segments for the three-month periods ended June 30, 2021 and 2020 are as follows: Electronics & Services & Intersegment Software Support Other Eliminations Total Three Months Ended June 30, 2021 Sales $ 9,307,000 $ 1,833,000 $ — $ ( 143,000 ) $ 10,997,000 Cost of sales 5,204,000 1,185,000 — — 6,389,000 Gross profit 4,103,000 648,000 — ( 143,000 ) 4,608,000 Selling, general and administrative expenses 3,592,000 878,000 663,000 ( 143,000 ) 4,990,000 Transaction costs — — 1,279,000 — 1,279,000 Operating income (loss) 511,000 ( 230,000 ) ( 1,942,000 ) — ( 1,661,000 ) Other (expense) income ( 38,000 ) 16,000 ( 257,000 ) — ( 279,000 ) Income (loss) before income tax $ 473,000 $ ( 214,000 ) $ ( 2,199,000 ) $ — $ ( 1,940,000 ) Depreciation and amortization $ 68,000 $ 139,000 $ 38,000 $ — $ 245,000 Capital expenditures $ — $ 1,000 $ — $ — $ 1,000 Assets $ 14,819,000 $ 7,624,000 $ 29,581,000 $ ( 27,000 ) $ 51,997,000 Electronics & Services & Intersegment Software Support Other Eliminations Total Three Months Ended June 30, 2020 Sales $ 8,287,000 $ 1,525,000 $ — $ ( 184,000 ) $ 9,628,000 Cost of sales 5,192,000 982,000 — ( 26,000 ) 6,148,000 Gross profit 3,095,000 543,000 — ( 158,000 ) 3,480,000 Selling, general and administrative expenses 3,638,000 483,000 769,000 ( 158,000 ) 4,732,000 Transaction costs — — 394,000 — 394,000 Operating (loss) income ( 543,000 ) 60,000 ( 1,163,000 ) — ( 1,646,000 ) Other income 3,000 — 276,000 — 279,000 (Loss) income before income tax $ ( 540,000 ) $ 60,000 $ ( 887,000 ) $ — $ ( 1,367,000 ) Depreciation and amortization $ 76,000 $ 19,000 $ 123,000 $ — $ 218,000 Capital expenditures $ 24,000 $ — $ 8,000 $ — $ 32,000 Assets $ 16,825,000 $ 6,569,000 $ 33,984,000 $ ( 27,000 ) $ 57,351,000 Electronics & Services & Intersegment Software Support Other Eliminations Total Six Months Ended June 30, 2021 Sales $ 17,671,000 $ 3,772,000 $ — $ ( 287,000 ) $ 21,156,000 Cost of sales 9,985,000 2,347,000 — — 12,332,000 Gross profit 7,686,000 1,425,000 — ( 287,000 ) 8,824,000 Selling, general and administrative expenses 7,200,000 1,857,000 1,391,000 ( 287,000 ) 10,161,000 Transaction costs — — 2,471,000 — 2,471,000 Operating income (loss) 486,000 ( 432,000 ) ( 3,862,000 ) — ( 3,808,000 ) Other (expense) income ( 57,000 ) 16,000 ( 251,000 ) — ( 292,000 ) Income (loss) before income tax $ 429,000 $ ( 416,000 ) $ ( 4,113,000 ) $ — $ ( 4,100,000 ) Depreciation and amortization $ 135,000 $ 293,000 $ 77,000 $ — $ 505,000 Capital expenditures $ 4,000 $ 6,000 $ — $ — $ 10,000 Electronics & Services & Intersegment Software Support Other Eliminations Total Six Months Ended June 30, 2020 Sales $ 16,823,000 $ 2,352,000 $ — $ ( 384,000 ) $ 18,791,000 Cost of sales 9,999,000 1,602,000 — ( 27,000 ) 11,574,000 Gross profit 6,824,000 750,000 — ( 357,000 ) 7,217,000 Selling, general and administrative expenses 7,535,000 811,000 1,683,000 ( 357,000 ) 9,672,000 Transaction costs — — 415,000 — 415,000 Operating loss ( 711,000 ) ( 61,000 ) ( 2,098,000 ) — ( 2,870,000 ) Other income (expense) 17,000 — 673,000 — 690,000 Loss before income tax $ ( 694,000 ) $ ( 61,000 ) $ ( 1,425,000 ) $ — $ ( 2,180,000 ) Depreciation and amortization $ 147,000 $ 32,000 $ 251,000 $ — $ 430,000 Capital expenditures $ 68,000 $ 1,000 $ 20,000 $ — $ 89,000

Net Loss Per Share

Net Loss Per Share	6 Months Ended

Net Loss Per Share [Abstract]
Net Loss Per Share	NOTE 13 – NET LOSS PER SHARE Basic net loss per common share is based on the weighted average number of common shares outstanding during each period and year. Diluted net income per common share takes into effect the dilutive effect of potential common shares outstanding. The Company’s only potential common shares outstanding are stock options and shares associated with the long-term incentive compensation plans, which resulted in no dilutive effect for the three and six months ended June 30, 2021 and 2020. The Company calculates the dilutive effect of outstanding options using the treasury stock method. Due to the net losses in the first three and six months of 2021, there was no dilutive impact from stock options or unvested shares. Options totaling 328,229 and 421,208 were excluded from the calculation of diluted earnings per share for the three and six months ended June 30, 2021, respectively because the exercise price was greater than the average market price of common stock during the period and there were no shares from deferred stock awards that would not have been included for the three and six months ended June 30, 2021, because of unmet performance conditions. Options totaling 614,114 and 634,114 were excluded from the calculation of diluted earnings per share for the three and six months ended June 30, 2020, respectively because the exercise price was greater than the average market price of common stock during the period and deferred stock awards totaling 117,688 shares would not have been included for the three and six months ended June 30, 2020, because of unmet performance conditions.

Fair Value Measurements

Fair Value Measurements [Abstract]
Fair Value Measurements	NOTE 14 – FAIR VALUE MEASUREMENTS The accounting guidance establishes a valuation hierarchy for disclosure of the inputs to valuation used to measure fair value. This hierarchy prioritizes the inputs into three broad levels as follows: Level 1 – Observable inputs that reflect unadjusted quoted prices for identical assets or liabilities in active markets that the Company has the ability to access at the measurement date. Level 2 – Observable inputs such as quoted prices for similar instruments and quoted prices in markets that are not active, and inputs that are directly observable or can be corroborated by observable market data. The types of assets and liabilities included in Level 2 are typically either comparable to actively traded securities or contracts, such as treasury securities with pricing interpolated from recent trades of similar securities, or priced with models using highly observable inputs, such as commodity options priced using observable forward prices and volatilities. Level 3 – Significant inputs to pricing that have little or no observability as of the reporting date. The types of assets and liabilities included in Level 3 are those with inputs requiring significant management judgment or estimation, such as the complex and subjective models and forecasts used to determine the fair value of financial instruments. Financial assets and liabilities measured at fair value on a recurring basis as of June 30, 2021 and December 31, 2020, are summarized below: June 30, 2021 Level 1 Level 2 Level 3 Total Fair Value Cash equivalents: Money Market Funds $ 11,564,000 $ — $ — $ 11,564,000 Subtotal 11,564,000 — — 11,564,000 Short-term investments: Corporate Notes/Bonds — 1,705,000 — 1,705,000 Subtotal — 1,705,000 — 1,705,000 Long-term investments: Corporate Notes/Bonds — 4,523,000 — 4,523,000 Convertible debt — — 374,000 374,000 Subtotal — 4,523,000 374,000 4,897,000 Total $ 11,564,000 $ 6,228,000 $ 374,000 $ 18,166,000 December 31, 2020 Level 1 Level 2 Level 3 Total Fair Value Cash equivalents: Money Market Funds $ 9,424,000 $ — $ — $ 9,424,000 Subtotal 9,424,000 — — 9,424,000 Short-term investments: Commercial Paper — 700,000 — 700,000 Corporate Notes/Bonds — 2,059,000 — 2,059,000 Subtotal — 2,759,000 — 2,759,000 Long-term investments: Corporate Notes/Bonds — 5,605,000 — 5,605,000 Convertible debt — — 605,000 605,000 Subtotal — 5,605,000 605,000 6,210,000 Current Liabilities: Contingent Consideration — — ( 550,000 ) ( 550,000 ) Subtotal — — ( 550,000 ) ( 550,000 ) Total $ 9,424,000 $ 8,364,000 $ 55,000 $ 17,843,000 The estimated fair value of contingent consideration as of December 31, 2020 was $ 550,000 , as noted above. The estimated fair value is considered a level 3 measurement because the probability weighted discounted cash flow methodology used to estimate fair value includes the use of significant unobservable inputs, primarily the contractual contingent consideration revenue targets and assumed probabilities. The Company paid the full amount of the contingent consideration during the first quarter of 2021 and there was no liability at June 30, 2021. We record transfers between levels of the fair value hierarchy, if necessary, at the end of the reporting period. There were no transfers between levels during the three months ended June 30, 2021.

Recent Accounting Pronouncements	NOTE 15 – RECENT ACCOUNTING PRONOUNCEMENTS In June 2016, FASB issued ASU 2016-13, "Financial Instruments - Credit Losses (Topic 326), Measurement of Credit Losses on Financial Instruments." The amendments in this update replace the incurred loss impairment methodology in current U.S. GAAP with a methodology that reflects expected credit losses. This ASU is intended to provide financial statement users with more decision-useful information about the expected credit losses and is effective for annual periods and interim periods for those annual periods beginning after December 15, 2022, which for us is the first quarter ending March 31, 2023. Entities may early adopt beginning after December 15, 2018. We are currently evaluating the impact of the adoption of ASU 2016-13 on our consolidated financial statements.

Subsequent Events	NOTE 16 – SUBSEQUENT EVENTS On August 2, 2021, the Company and Lantronix, Inc. (“Lantronix”) completed the sale by CSI to Lantronix of all of the issued and outstanding stock of CSI’s wholly owned subsidiary, Transition Networks, Inc., and the entire issued share capital of its wholly owned subsidiary, Transition Networks Europe Limited (collectively with Transition Networks, Inc., the “TN Companies”), pursuant to the securities purchase agreement dated April 28, 2021 (“E&S Sale Transaction”). At the closing of the E&S Sale Transaction, Lantronix paid CSI approximately $ 24,160,000 in cash, which was based on $ 25,027,566 base purchase price, as adjusted by estimated closing net working capital. This amount may be further adjusted to reflect the final closing net working capital amount. Under the securities purchase agreement, Lantronix has also agreed to pay CSI, if earned, earnout payments of up to $ 7.0 million payable following two successive 180 -day intervals after the closing of the E&S Sale Transaction based on revenue targets for the business of the TN Companies as specified in the securities purchase agreement, subject to certain adjustments and allocations as further described in the securities purchase agreement. Concurrently with the closing of the transaction, CSI and Lantronix entered into a transition services agreement under which CSI will perform administrative and IT services, and lease office, warehouse and production space to Lantronix at CSI’s Minnetonka, Minnesota facility for a period of up to twelve months . In contemplation of the closing of the E&S Sale Transaction, the employment of approximately 75 employees of CSI or the TN Companies were terminated. As provided in the securities purchase agreement, CSI is responsible for any severance obligations arising out of such termination. Lantronix hired 63 former employees effective as of the closing of the E&S Sale Transaction as described in the securities purchase agreement. The Company will record a charge in the third quarter of 2021 relating to employee severance payments that is expected to be approximately $ 1,250,000 . The Company also expects to record a non-cash charge of approximately $ 325,000 relating to the acceleration and settlement of outstanding equity awards under the 2011 Executive Incentive Compensation Plan as described below. The closing of the E&S Sale Transaction constituted a “Change in Control” as defined in the Company’s 2011 Executive Incentive Compensation Plan (“2011 Plan”) on August 2, 2021, the closing date of the E&S Sale Transaction. In accordance with the determinations and approvals of the Compensation Committee, effective on August 1, 2021, each Incentive Award granted and outstanding under the 2011 Plan and not otherwise forfeited or expired in accordance with its terms was fully vested and exercisable and any restrictions lapsed. After giving effect to such acceleration and vesting, on the August 2, 2021 closing date:  All then-outstanding restricted stock units (RSUs”) were settled by exchanging them for the equivalent number of shares of the Company’s common stock specified in the respective RSU award agreements, with the shares of the Company’s common stock issued on settlement of the RSUs being issued and outstanding as of the closing date.  All then-outstanding stock options having an exercise price less than the Fair Market Value (as defined in the 2011 Plan) on the closing date were settled by exchanging the options for a “net” number of shares of the Company’s common stock as if exercised on a net or cashless basis as provided in the 2011 Plan (for administrative convenience, rounded up to the next whole share), with the net shares of the Company’s common stock issued on settlement of these stock options being issued and outstanding as of the closing date.  Following the disposition of the outstanding RSUs and stock options as described above, these Incentive Awards were terminated and cancelled as of the closing date.  All then-outstanding stock options having an exercise price equal to or greater than the Fair Market Value on the closing date were terminated and cancelled as of the closing date without any payment therefor.  Any required tax withholding not otherwise satisfied in cash on the closing date is being satisfied by the Company reducing the shares otherwise issuable to the holder of the Incentive Award by that number of whole shares (rounded up to the nearest whole share) having a Fair Market Value (as defined in the 2011 Plan) equal to the amount of any tax withholding required. Immediately prior to the closing date, there were outstanding under the 2011 Plan stock options to purchase 995,530 shares of CSI common stock and RSUs for 98,705 shares of CSI common stock. Immediately following the closing date, there were no equity incentive awards outstanding under the 2011 Plan or otherwise.

Description of Business	Description of Business Communications Systems, Inc. (herein collectively referred to as “CSI,” “our,” “we” or the “Company”) is a Minnesota corporation organized in 1969 that has classified its business into two segments: (1) the Electronics & Software segment (consisting of US-based subsidiary Transition Networks and UK-based subsidiary Net2Edge) which (i) manufactures and sells solutions that provide actionable intelligence, power and connectivity at the edge of networks through PoE products, software and services as well as traditional products such as media converters, network adapters and other connectivity products and (ii) designs, develops, and sells edge network access products, TDM (time-division multiplexing) over IP and other circuit emulation solutions, along with specialized cloud-based software solutions, primarily within the telecommunications market; and (2) the Services and Support segment (consisting of subsidiaries JDL and Ecessa), which (i) provides technology solutions including virtualization, managed services, wired and wireless network design and implementation, and hybrid cloud infrastructure and deployment and (ii) designs, develops, and sells SD-WAN (software-designed wide-area network) solutions. As described in Note 16 of Notes to Financial Statements, on August 2, 2021, the Company and Lantronix, Inc. completed the sale by CSI to Lantronix of all of the issued and outstanding stock of CSI’s wholly owned subsidiary, Transition Networks, Inc., and the entire issued share capital of its wholly owned subsidiary, Transition Networks Europe Limited (collectively with Transition Networks, Inc., the “TN Companies”), pursuant to the securities purchase agreement dated April 28, 2021 (“E&S Sale Transaction”). For purposes of this Form 10-Q, the Company classifies its businesses into the two segments discussed above. Non-allocated general and administrative expenses are separately accounted for as “Other” in the Company’s segment reporting. Intersegment revenues are eliminated upon consolidation.
Financial Statement Presentation	Financial Statement Presentation The condensed consolidated balance sheet as of June 30, 2021, the related condensed consolidated statements of loss and comprehensive loss, the condensed consolidated statements of changes in stockholders’ equity for the three and six months ended June 30, 2021 and 2020, and the condensed consolidated statements of cash flows for the periods ended June 30, 2021 and 2020 have been prepared by Company management. In the opinion of management, all adjustments (which include only normal recurring adjustments, except where noted) necessary to present fairly the financial position, results of operations, and cash flows at June 30, 2021 and 2020 and for the periods then ended have been made. Certain information and footnote disclosures normally included in consolidated financial statements prepared in accordance with generally accepted accounting principles in the United States of America have been condensed or omitted. We recommend these condensed consolidated financial statements be read in conjunction with the financial statements and notes thereto included in the Company’s December 31 , 2020 Annual Report to Shareholders on Form 10-K (“2020 Form 10-K”). The results of operations for the period ended June 30, 2021 are not necessarily indicative of operating results for the entire year. The presentation of financial statements in conformity with generally accepted accounting principles requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities, and disclosure of contingent assets and liabilities at the balance sheet date, and the reported amounts of revenues and expenses during the reporting period. The estimates and assumptions used in the accompanying condensed consolidated financial statements are based upon management’s evaluation of the relevant facts and circumstances as of the time of the financial statements. Actual results could differ from those estimates. Except to the extent updated or described below, the significant accounting policies set forth in Note 1 to the consolidated financial statements in the December 31, 2020 Form 10-K, appropriately represent, in all material respects, the current status of accounting policies, and are incorporated herein by reference.
