Subsequent Event [Abstract]
SUBSEQUENT EVENT	9. SUBSEQUENT EVENT On July 13, 2012, we acquired Ascade, an independent Swedish software company who provides trading and routing software solutions to telecommunications companies globally. The total cost of the acquisition, excluding acquisition-related costs, was approximately $19 million and was paid in cash from our existing cash resources. We acquired Ascade to integrate Acsade’s trading and routing solution, Ascade7, into our Wholesale Business Management Solution (“WBMS”) and to expand and strengthen our geographic presence in the telecommunications wholesale marketplace. We are in the early stages of the Ascade purchase accounting, but estimate a significant portion of the purchase price will be allocated to acquired intangible assets, including goodwill. The results of Ascade will be included in our results of operations for the periods subsequent to the acquisition date. Pro forma information on our historical results of operations to reflect the acquisition of Ascade will not be presented as Ascade’s results of operations during the prior periods are not material to our results of operations.
