Income Tax Disclosure [Abstract]
Income Tax Disclosure [Text Block]	Note 19. Income Taxes The provision for income taxes for both the three months ended June 30, 2011 and 2010 was $0.1 million. The provision for income taxes for both the six months ended June 30, 2011 and 2010 was $0.2 million. The provision for income taxes relates to certain of TranSwitch’s subsidiaries located in foreign jurisdictions. The effective income tax rate differs from the U.S. federal statutory rate for the periods presented primarily due to foreign and state income taxes and increases in the valuation allowance for deferred income tax assets offset by non-deductible interest expense. During the three and six months ended June 30, 2011 and 2010, we evaluated our deferred income tax assets as to whether it is “more likely than not” that the deferred income tax assets will be realized. In our evaluation of the realizability of deferred income tax assets, we consider projections of future taxable income, the reversal of temporary differences and tax planning strategies. We have evaluated the realizability of the deferred income tax assets and have determined that it is “more likely than not” that all of the deferred income tax assets will not be realized. Accordingly, a valuation allowance was recorded for all of our domestic net deferred income tax assets. In future periods, we will not recognize a deferred tax benefit and will maintain a deferred tax valuation allowance until we achieve sustained U.S. taxable income. Additionally, in the future, we expect our current income tax expense to be related to taxable income generated by our foreign subsidiaries. The Company is required to make a determination of any of its tax positions (federal and state) for which the sustainability of the position, based upon the technical merits, is uncertain. The Company regularly evaluates all tax positions taken and the likelihood of those positions being sustained. If management is highly confident that the position will be allowed and there is a greater than 50% likelihood that the full amount of the tax position will be ultimately realized, the company recognizes the full benefit associated with the tax position. Additionally, interest and penalties related to uncertain tax positions are included as a component of income tax expense.

The provision for income taxes for both the three months ended June 30, 2011 and 2010 was $0.1 million.
