Organization, Consolidation and Presentation of Financial Statements [Abstract]
Basis of Presentation	(b) Basis of Presentation The accompanying unaudited condensed consolidated financial statements have been prepared in accordance with accounting principles generally accepted in the United States of America (U.S. GAAP) for interim financial information and with the instructions to Form 10-Q and Article 3 of Regulation S-X. Accordingly, they do not include all of the information and footnotes required by U.S. GAAP for complete financial statements. These financial statements include the accounts of the Company and its wholly owned subsidiaries. These unaudited condensed consolidated financial statements should be read in conjunction with the consolidated financial statements of the Company and notes thereto included in the Company’s Annual Report on Form 10-K/A for the year ended December 31, 2022 filed with the Securities and Exchange Commission (“SEC”) on August 12, 2024. For a complete description of what the Company believes to be the critical accounting policies and estimates used in the preparation of its unaudited condensed consolidated financial statements, refer to the Company’s Annual Report on Form 10-K/A for the year ended December 31, 2022. All intercompany transactions and balances have been eliminated in consolidation. The unaudited condensed consolidated financial statements reflect all adjustments (consisting only of normal recurring adjustments) that, in the opinion of management, are necessary for a fair presentation of the results for the interim periods presented. The results of operations for the current interim period are not necessarily indicative of results to be expected for the current year or any other period.
Risks and Uncertainties	(c) Risks and Uncertainties The accompanying unaudited condensed consolidated financial statements have been prepared in conformity with U.S. GAAP, assuming the Company will continue as a going concern. We continue to be exposed to macroeconomic pressures in the post-COVID-19 environment, including concerns about energy costs, geopolitical issues, inflation, the availability and cost of credit, business and consumer confidence, and unemployment. We have seen improvement in our supply chain in 2023 as supply chain pricing, freight and logistics costs, product and component availability, and extended lead-times which were a challenge in 2021 and 2022 begin to alleviate in 2023 as the world economy recovers from the COVID-19 pandemic. We expect elevated costs for components and expedite fees to further improve throughout 2023. We conduct significant business in South Korea, Japan, Vietnam, India, Spain, and Canada, as well as in other countries in Europe, Asia-Pacific, Middle East and Latin America, all of which subject us to foreign currency exchange rate risk. The local currencies of our significant foreign subsidiaries are the South Korean Won ("KRW"), Japanese Yen ("JPY"), Euro ("EUR), and Pound Sterling ("GBP"). Revenues and operating expenses are typically denominated in the local currency of each country and result from transactions by our operations in these countries. However, a significant portion of our international cost of sales is denominated in the U.S. Dollar (“USD”). As of March 31, 2023, the Company's debt obligation under the Term Loan was $23.7 million, net of unamortized issuance cost of $0.4 million, of which $1.3 million is scheduled for payment in the next 12 months. Due to the risk of non-compliance with certain financial covenants in the next 12 months we classified the entire amount as a current liability. As of March 31, 2023, we were in discussion with the lenders to amend the debt agreement to mitigate the risk of non-compliance. Refer to Note 16 Subsequent events for further information about the amendment and subsequent termination of the JPMorgan Credit Agreement. In addition to negotiating for revised financial covenants, we continue to focus on cost management, operating efficiency and efficient discretionary spending. Management is actively taking measures to enhance profitability and liquidity, including reducing the Company’s cost structure and cash outflows, including its investment in inventory, and managing receivable balances through aggressive collection efforts and tighter customers payment terms. These plans are not completely within the Company’s control, as some actions are dependent on the Company’s lenders, vendors and customers. However, the Company believes that it will maintain liquidity in the next 12 months to support its operations.
Use of Estimates	(d) Use of Estimates The preparation of the unaudited condensed consolidated financial statements in conformity with U.S. GAAP 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 unaudited condensed consolidated financial statements and the reported amounts of revenue and expenses during the reporting period. Actual results could differ materially from those estimates.
Concentration of Risk	(g) Concentration of Risk Financial instruments that potentially subject the Company to concentrations of credit risk consist primarily of cash, cash equivalents and restricted cash, accounts receivables, and contract assets. Cash, cash equivalents and restricted cash consist of financial deposits and money market accounts that are principally held with various domestic and international financial institutions with high credit standing. As of March 31, 2023, the Company had cash accounts in excess of Federal Deposit Insurance Corporation ("FDIC") insured limits. The Company’s customers include competitive and incumbent local exchange carriers, competitive access providers, internet service providers, wireless carriers and resellers serving these markets. The Company performs ongoing credit evaluations of its customers and generally does not require collateral. Allowances are maintained for potential doubtful accounts based upon the expected collectability of accounts receivable using historical loss rates adjusted for customer-specific factors and current economic conditions. The Company determines historical loss rates on a rational and systematic basis. The Company performs periodic assessments of its customers’ liquidity and financial condition through analysis of information obtained from credit rating agencies, financial statement review and historical and current collection trends.
Business Combinations	(h) Business Combinations We account for business combinations using the acquisition method, which requires the identification of the acquirer, the determination of the acquisition date and the allocation of the purchase price paid by the acquirer to the identifiable tangible and intangible assets acquired, the liabilities assumed, including any contingent consideration and any noncontrolling interest in the acquiree at their acquisition date fair values. Goodwill represents the excess of the purchase price over the fair value of net assets acquired, including the amount assigned to identifiable intangible assets. Identifiable intangible assets with finite lives are amortized over their expected useful lives. Acquisition-related costs are expensed in the periods in which the costs are incurred. The results of operations of acquired businesses are included in our consolidated financial statements from the acquisition date.
Restructuring and Other Charges	(i) Restructuring and Other Charges From time to time, the Company takes actions to align its workforce, facilities and operating costs with perceived market opportunities, business strategies and changes in market and business conditions. The Company recognizes a liability for the cost associated with an exit or disposal activity in the period in which the liability is incurred, except for one-time employee termination benefits, which are measured at the communication date and recognized ratably over the required service period, if any.
Recent Accounting Pronouncements	(j) Recent Accounting Pronouncements In October 2021, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update (“ASU”) 2021-08, Business Combinations (Topic 805): Accounting for Contract Assets and Contract Liabilities from Contracts with Customers, which requires the Company to apply ASC 606, Revenue from Contracts with Customers, to recognize and measure contract assets and contract liabilities from contracts with customers acquired in a business combination. Before the update such balances were measured and recognized at fair value on the acquisition date. The ASU is effective for fiscal years beginning after December 15, 2022, including interim periods within those fiscal years. Early adoption is permitted, including in interim periods. The Company adopted these requirements prospectively, effective on the first day of the second quarter of year 2022. There was no material impact on our consolidated financial statements on the adoption date. In June 2016, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update (“ASU”) 2016-13, Financial Instruments – Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments, which requires the Company to measure and recognize expected credit losses for financial assets held and not accounted for at fair value through net income. In November 2018, April 2019 and May 2019, the FASB issued ASU No. 2018-19, Codification Improvements to Topic 326, Financial Instruments - Credit Losses, ASU No. 2019-04, Codification Improvements to Topic 326, Financial Instruments - Credit Losses, and ASU No. 2019-05, Financial Instruments - Credit Losses (Topic 326): Targeted Transition Relief, which provided additional implementation guidance on the previously issued ASU. The Company adopted the updated guidance on January 1, 2022, utilizing the modified retrospective transition method and recorded a cumulative-effect adjustment of $0.4 million to accumulated deficit.
