First TDM-Over-IP Device Enters Comm Market

By way of a joint venture with RAD Data Communications, the company has unveiled the PacketTrunk-4 (TXC-05870) as the comm market's first TDM-over-IP (TDMoIP) device. The device is earmarked for use in creating a family of VLSI products that, in turn, can be used to develop TDMoIP-capable network equipment while allowing transparent transport of legacy TDM and serial data over IP/MPLS networks. It's essentially an inter-networking gateway device that transports TDM trunks over packet-switched networks (PSNs) using TDMoIP. Features of the new comm device include comprehensive clock recovery, jitter compensation, Layer 2/3/4 QoS support, and standards-based support for transport of structured and unstructured TDM signals over a PSN. The 256-pin, 27 x 27-mm PBGA has a 2.5V core and 3.3V I/O with power consumption of approximately 1.2W. The device comes with an RTOS-independent, hardware-abstracting API-based device driver, evaluation kit, TDMoIP calculator spreadsheet, BSDL, and IBIS models. Price is $70 each in production quantities.For more details, contact TRANSWITCH CORP., Shelton, CT. (203) 929-8810.
