Chip provides TDM circuit emulation over IP, Ethernet networks

Shelton, Conn.— Transwitch's PacketTrunk-4Plus is a single-chip device that enables transparent transport of legacy TDM traffic over IP, MPLS and Ethernet networks.

PacketTrunk-4 Plus is the latest device in TranSwitch’s portfolio of convergence products for access and edge networks. It is designed to implement standards-compliant circuit emulation service (CES) interfaces and systems. CES is complementary to VoIP and offers a migration path for transporting T1, E1, T3 and E3 circuits over packet-switched networks (PSN).

PacketTrunk4-Plus incorporates G.823/G.824 synchronization interface (less than 15-ppb, 1 sec) quality clock recovery, encapsulation (IPv4, IPv6, MPLS, L2TPv3, Ethernet), jitter compensation, Layer 2/3/4 QoS support and support for transport of structured and unstructured TDM signals over a PSN.

PacketTrunk-4 Plus is available now with an RTOS-independent hardware-abstraction layer (HAL), evaluation kit, TDMoIP calculator spreadsheet, BSDL and IBIS models, and extensive documentation.

PacketTrunk-4 Plus is backward compatible to the first-generation PacketTrunk-4, providing an easy migration path. The device is packaged in a 256-pin 27 x 27 mm PBGA. Power supply voltages are 1.5v core and 3.3v I/O.

Pricing on the PacketTrunk-4 Plus is $70 for 1K quantity.
