Goodwill [Abstract]
Goodwill and Intangible Assets Disclosure [Text Block]	Goodwill The Company reviews goodwill for impairment annually at the beginning of its fourth fiscal quarter and whenever events or changes in circumstances indicate the carrying value of goodwill may not be recoverable. Conditions that would trigger an impairment assessment, include, but are not limited to, a significant adverse change in legal factors or in the business climate that could affect the value of an asset or an adverse action. The Company is considered one reporting unit. The goodwill impairment test involves a two-step process pursuant to Accounting Standards Codification ("ASC") 350-20-35. The first step compares the fair value of the reporting unit to its carrying value. If the fair value of the reporting unit exceeds its carrying value, goodwill is not impaired and no further testing is required. If the fair value of the reporting unit is less than the carrying value, the second step of the impairment test is to measure the amount of impairment loss. In the second step, the reporting unit's fair value is allocated to all of the assets and liabilities of the reporting unit, including any unrecognized intangible assets, in a hypothetical analysis that calculates the implied fair value of goodwill in the same manner as if the reporting unit was being acquired in a business combination. If the implied fair value of the reporting unit's goodwill is less than the carrying value, the difference is recorded as an impairment loss. During the three months ended September 30, 2012, the Company determined that sufficient indicators of potential impairment existed to require an interim goodwill impairment assessment. These indicators included the recent trading value of the Company's common stock, coupled with overall telecommunications market conditions. As a result, the Company compared its book value to its market capitalization, adjusted for factors such as a control premium and concluded step two of the impairment test should be performed. The Company estimated the fair value of its single reporting unit using a market approach. The market approach estimates fair value in part on market capitalization plus an estimated control premium paid in acquisitions of publicly traded companies with similar characteristics to the Company. Based on the Company's analysis, the implied fair value of goodwill was lower than its carrying value. As a result, the Company recorded a full impairment charge of $29.7 million against the carrying amount of goodwill during the three months ended September 31, 2012. The impairment charge is included in Impairment of goodwill in the Condensed Consolidated Statements of Operations.

The Company reviews goodwill for impairment annually at the beginning of its fourth fiscal quarter and whenever events or changes in circumstances indicate the carrying value of goodwill may not be recoverable. Conditions that would trigger an impairment assessment, include, but are not limited to, a significant adverse change in legal factors or in the business climate that could affect the value of an asset or an adverse action. The Company is considered one reporting unit.

The goodwill impairment test involves a two-step process pursuant to Accounting Standards Codification ("ASC") 350-20-35. The first step compares the fair value of the reporting unit to its carrying value. If the fair value of the reporting unit exceeds its carrying value, goodwill is not impaired and no further testing is required. If the fair value of the reporting unit is less than the carrying value, the second step of the impairment test is to measure the amount of impairment loss. In the second step, the reporting unit's fair value is allocated to all of the assets and liabilities of the reporting unit, including any unrecognized intangible assets, in a hypothetical analysis that calculates the implied fair value of goodwill in the same manner as if the reporting unit was being acquired in a business combination.
