The TX3-ATA is a single-port analog telephone adapter (ATA) that allows users to create a high-quality and manageable IP telephony solution for residential and office environments. Its ultra-compact size, voice quality, advanced VoIP functionality, security protection, and auto provisioning options enable users to take advantage of VoIP on analog phones. It also allows service providers to offer high-quality IP service to their market. The TX3-ATA is an ideal ATA for individual use as well as commercial IP voice deployments worldwide. Telecom carriers are accelerating the transition from PSTN (Public Switched Telephone Network, A.K.A. POTS) to all-IP communications. Traditional voice services, usually routed through the fixed-line analog network, are then routed through a voice-over-IP digital network. Rather than using PSTN, calls are transferred over high-bandwidth internet links reaching the home. This can be done over the existing copper lines with xDSL technology or over Cable or Optic Fiber installed for copper line termination. Mircom is offering the ATA (Analog Telephone Adapter) hardware along with a monthly service subscription.
