| Summary Of Significant Accounting Policies [Abstract] | |||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
| Description Of Business |
Description of business: Communications Systems, Inc. (herein collectively called “CSI,” “our” or the “Company”) is a Minnesota corporation organized in 1969 that operates directly and through its subsidiaries located in the United States, Costa Rica, and the United Kingdom. CSI is principally engaged through its Suttle business unit in the manufacture and sale of connectivity infrastructure products for broadband and voice communications and through its Transition Networks business unit in the manufacture of core media conversion products, Ethernet switches, and other connectivity and data transmission products. Through its JDL Technologies business unit the Company provides technology solutions including virtualization, managed services, wired and wireless network design and implementation, HIPAA-compliant IT services, and converged infrastructure configuration and deployment. Through its Net2Edge business unit, the Company enables telecommunications carriers to connect legacy networks to high-speed services. The Company classifies its businesses into four segments: Suttle, which manufactures connectivity infrastructure products for broadband and voice communications; Transition Networks, which designs and markets media conversion products, Ethernet switches, and other connectivity and data transmission products; JDL Technologies, which is an IT managed services provider and value-added reseller; and Net2Edge, which develops products to connect legacy networks to high-speed services. Non-allocated general and administrative expenses are separately accounted for as “Other” in the Company’s segment reporting. Intersegment revenues are eliminated upon consolidation.

| Principles Of Consolidation |
Principles of consolidation: The consolidated financial statements include the accounts of the Company and its subsidiaries. All intercompany transactions and accounts have been eliminated.
|
||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
| Use Of Estimates |
Use of estimates: The presentation of financial statements in conformity with accounting principles generally accepted in the United States of America 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 date of the financial statements and the reported amounts of revenues and expenses during the reporting period. The Company uses estimates based on the best information available in recording transactions and balances resulting from operations. Actual results could differ from those estimates. The Company’s estimates consist principally of reserves for doubtful accounts, sales returns, warranty costs, asset impairment evaluations, accruals for compensation plans, self-insured medical and dental accruals, lower of cost or market inventory adjustments, provisions for income taxes and deferred taxes and depreciable lives of fixed assets.

| Cash Equivalents |
Cash equivalents: For purposes of the consolidated statements of cash flows, the Company considers all highly liquid investments with a maturity of three months or less at the time of purchase to be cash equivalents. As of December 31, 2016, the Company had $10,443,000 in cash and cash equivalents. Of this amount, $3,851,000 was invested in short-term money market funds that are not considered to be bank deposits and are not insured or guaranteed by the federal deposit insurance company (FDIC) or other government agency. These money market funds seek to preserve the value of the investment at $1.00 per share; however, it is possible to lose money investing in these funds. The remainder is operating cash and certificates of deposit which are fully insured through the FDIC.
|
||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
| Investments |
Investments: Investments consist of certificates of deposit and corporate notes and bonds that are traded on the open market and are classified as available-for-sale at December 31, 2016. Available-for-sale investments are reported at fair value with unrealized gains and losses excluded from operations and reported as a separate component of stockholders’ equity, net of tax (see Accumulated other comprehensive loss below).
|
||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
| Inventories |
Inventories: Inventories are stated at the lower of cost or market. Cost is determined by the first-in, first-out method. Provision to reduce inventories to the lower of cost or market is made based on a review of excess and obsolete inventories, estimates of future sales, examination of historical consumption rates and the related value of component parts.
|
||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
| Property, Plant And Equipment |
Property, plant and equipment: Property, plant and equipment are recorded at cost. Depreciation is computed using the straight-line method. Depreciation included in cost of sales and selling, general and administrative expenses for continuing operations was $3,609,000, $3,212,000 and $2,375,000 for 2016, 2015 and 2014, respectively. Maintenance and repairs are charged to operations and additions or improvements are capitalized. Items of property sold, retired or otherwise disposed of are removed from the asset and accumulated depreciation accounts and any gains or losses on disposal are reflected in operations.
|
||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
| Intangible Assets |
Intangible Assets: Intangible assets with indefinite useful lives are not amortized, but are tested at least annually for impairment.
|
||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
| Recoverability Of Long-Lived Assets |
Recoverability of long-lived assets: The Company reviews its long-lived assets periodically when impairment indicators exist as required under generally accepted accounting principles. Potential impairment is determined by comparing the carrying value of the assets with expected net cash flows expected to be provided by operating activities of the business or related products. If the sum of the expected future net cash flows is less than the carrying value, an impairment loss would be measured by comparing the amount by which the carrying value exceeds the fair value of the asset.
|
||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
| Warranty |
Warranty: The Company reserves for the estimated cost of product warranties at the time revenue is recognized. We estimate the costs of our warranty obligations based on our warranty policy or applicable contractual warranty, historical experience of known product failure rates, and use of materials and service delivery costs incurred in correcting product failures. Management reviews the estimated warranty liability on a quarterly basis to determine its adequacy. The following table presents the changes in the Company’s warranty liability for the years ended December 31, 2016 and 2015, which relate to normal product warranties and a five-year obligation to provide for potential future liabilities for certain network equipment sales:

| Accumulated Other Comprehensive Loss |
Accumulated other comprehensive loss: The components of accumulated other comprehensive loss are as follows:
The Company recognized $4,238,000 in foreign currency translation losses within the income statement during the first quarter due to the substantial liquidation of our Austin Taylor subsidiary in the U.K. Refer to Note 7 for further information regarding the pension liability adjustment recognized in income in the first quarter of 2016. The functional currency of Austin Taylor and Net2Edge is the British pound. Assets and liabilities denominated in this foreign currency were translated into U.S. dollars at year-end exchange rates. Revenue and expense transactions were translated using average exchange rates. Suttle Costa Rica uses the U.S. dollar as their functional currency.
|
||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
| Revenue Recognition |
Revenue recognition: The Company’s manufacturing operations (Suttle, Transition Networks and Net2Edge) recognize revenue when the earnings process is complete, evidenced by persuasive evidence of an agreement, delivery has occurred or services have been rendered, the price is fixed or determinable, and collectability is reasonably assured. Revenue is recognized for domestic and international sales at the shipping point or delivery to customers, based on the related shipping terms. Risk of loss transfers at the point of shipment or delivery to customers, and the Company has no further obligation after such time. Sales are made directly to customers and through distributors. Payment terms for distributors are consistent with the terms of the Company’s direct customers. The Company records a provision for sales returns, sales incentives and warranty costs at the time of the sale based on historical experience and current trends.
|
||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
| Research And Development |
Research and development: Research and development costs consist of outside testing services, equipment and supplies associated with enhancing existing products and developing new products. Research and development costs are expensed when incurred and totaled $5,366,000 in 2016, $8,291,000 in 2015 and $7,835,000 in 2014.
|
||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
| Net Income Per Share |
Net income per share: Basic net income per common share is based on the weighted average number of common shares outstanding during each year. Diluted net income per common share adjusts for 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 2016 and 2015 and a dilutive effect of 18,384 shares in 2014. The Company calculates the dilutive effect of outstanding options and unvested shares using the treasury stock method. Due to the net loss in 2016 and 2015, there was no dilutive impact from outstanding stock options or unvested shares. The number of shares not included in the computation of diluted earnings per share because the options’ exercise price was greater than the average market price of common stock during the year for 2014 was 243,427. Options totaling 902,930 would have been excluded from the calculation of diluted earnings per share for year ended December 31, 2016, because the exercise price was greater than the average market price of common stock during the period and deferred stock awards totaling 133,982 shares would not have been included because of unmet performance conditions. Options totaling 691,924 would have been excluded from the calculation of diluted earnings per share for year ended December 31, 2015, because the exercise price was greater than the average market price of common stock during the period and deferred stock awards totaling 95,668 shares would not have been included because of unmet performance conditions.

| Share Based Compensation |
Share based compensation: The Company accounts for share based compensation awards on a fair value basis. The estimated grant date fair value of each stock-based award is recognized in income over the requisite service period (generally the vesting period). The estimated fair value of each option is calculated using the Black-Scholes option-pricing model.

| Accounting Standards Issued |
Accounting standards issued: In May 2014, the Financial Accounting Standards Board (FASB) issued a new accounting standard update on revenue recognition from contracts with customers. The new guidance will replace all current U.S. GAAP guidance on this topic and eliminate all industry-specific guidance. According to the new guidance, revenue is recognized when promised goods or services are transferred to customers in an amount that reflects the consideration the Company expects to receive in exchange for those goods or services. As a result of the FASB’s July 2015 deferral of the standard’s required implementation date, the guidance is effective for interim and annual reporting periods beginning after December 15, 2017. The guidance permits companies to either apply the requirements retrospectively to all prior periods presented, or apply the requirements in the year of adoption, through a cumulative adjustment. We plan to adopt the modified retrospective approach. We are still evaluating the impact of this adoption and anticipate that the most significant impact will be within our JDL Technologies segment. In July 2015, the FASB issued an accounting standard on inventory, which simplifies the subsequent measurement of inventory by requiring entities to measure inventory at the lower of cost or net realizable value, except for inventory measured using the last-in, first-out (LIFO) or the retail inventory methods. This standard requires entities to compare the cost of inventory to one measure – net realizable value. Net realizable value is the estimated selling price in the ordinary course of business, less reasonably predictable costs of completion, disposal and transportation. The standard is effective for the annual period beginning after December 15, 2016 and interim periods within those annual periods, with early adoption permitted, and is to be applied prospectively. The Company does not expect the adoption of this standard to have a material impact on its consolidated financial statements. In November 2015, the FASB issued an accounting standard on deferred taxes, which removes the requirement to present deferred tax assets and liabilities as current and noncurrent on the balance sheet based on the classification of the related asset or liability, and instead requires classification of all deferred tax assets and liabilities as noncurrent. This guidance will be effective for interim and annual reporting periods beginning after December 15, 2016, and early adoption is permitted. Other than the prescribed classification of all deferred tax assets and liabilities as noncurrent, the Company does not expect the implementation of this standard to have a material impact on its consolidated financial statements. In February 2016, the FASB issued new accounting requirements regarding accounting for leases, which requires an entity to recognize both assets and liabilities arising from financing and operating leases, along with additional qualitative and quantitative disclosures. The new standard is effective for fiscal years beginning after December 15, 2018, including interim periods within that reporting period, and early adoption is permitted. The Company does not expect the adoption of this standard to have a material impact on its consolidated financial statements. In March 2016, the FASB issued a new accounting standard that will change certain aspects of accounting for share-based payments to employees, including the accounting for income taxes, forfeitures and statutory withholding requirements, as well as classification in the statement of cash flows. The new standard is effective for annual and interim periods beginning after December 15, 2016. The Company does not expect the adoption of this standard to have a material impact on its consolidated financial statements. In August 2016, the FASB issued new accounting guidance regarding the classification of cash receipts and payments in the Statement of Cash Flows. This guidance is intended to reduce diversity in practice in how certain cash receipts and cash payments are presented and classified in the Consolidated Statement of Cash Flows by providing guidance on eight specific cash flow issues. The new standard is effective retrospectively on January 1, 2018, with early adoption permitted. We have not yet determined the impact this standard will have on our financial condition or results of operations.

| Accounting Standards Adopted |
Accounting standards adopted: In April 2015, the FASB issued accounting guidance that changes the presentation of debt issuance costs. The core principle of this revised accounting guidance is that debt issuance costs are not assets, but adjustments to the carrying cost of debt. The Company adopted this guidance in the first quarter of 2016 with no material impact on its consolidated financial statements. In August 2014, the FASB issued accounting guidance that amended the existing requirements for disclosing information about an entity’s ability to continue as a going concern and explicitly requires management to assess an entity’s ability to continue as a going concern and to provide related footnote disclosure in certain circumstances. This guidance was effective for annual periods ending after December 15, 2016, and annual and interim periods thereafter. The Company adopted this guidance in 2016 and management does not believe there is substantial doubt about the entity’s ability to continue as a going concern.
