TranSwitch and RAD to develop TDMoIP devices for packet-switched networks

8 January 2003 -- TranSwitch Corp and RAD Data Communications are partnering on a new family of TDM over IP silicon chips for TDMoIP-capable network equipment that will enable transparent transport of legacy TDM and serial data over IP/MPLS networks.

8 January 2003 -- Connecticut-based high-speed semiconductor supplier TranSwitch Corp and Tel Aviv-based access equipment maker RAD Data Communications Ltd have a strategic technology partnership and OEM agreement to introduce a new family of TDM over IP (TDMoIP) VLSI products that can be used to develop TDMoIP-capable network equipment. These devices will enable transparent transport of legacy TDM and serial data over IP/MPLS networks.

"Packet-switched networks are not designed to provide TDM services," explains Tal Gilad, RAD's TDMoIP product manager. "TDMoIP enables transmission of TDM traffic over asynchronous networks while overcoming packet loss and delay variations introduced by those networks."

TDMoIP, which RAD developed and introduced at Telecom Geneva in 1999, is now has been deployed in over 2500 links worldwide to carry TDM over the packet-switched networks of carriers, metropolitan area networks (MANs) and enterprises (see www.tdmoip.com). "We are confident that as more vendors adopt the TDMoIP solution, it will emerge as the industry standard for legacy migration," says Gilad.

RAD is working in the IETF and MPLS Forums to promote TDMoIP as a standard for transporting TDM traffic over packet networks.
"TDM over IP technology enables evolutionary migration of voice traffic to packet-switched networks," said David Fraley, principal analyst at Gartner Inc. "It allows next-generation carriers to broaden their range of services to include legacy TDM and signaling such as SS7, ISDN and Q.SIG as well as packet-based offerings."

"TranSwitch recognises enormous potential in developing solutions for the transitional communications market, which involves transporting legacy services over next-generation networks and next-generation services over legacy infrastructure," said Brian Stroehlein, product marketing manager at TranSwitch. "The new TDMoIP family will expand our portfolio of access and edge products and work seamlessly with existing devices."
