Zarlink Launches Lower Density Circuit Emulation Chips for Packet Networks

Zarlink Semiconductor launched three low-density CES (Circuit Emulation Services)-over- Packet processors designed to "tunnel" one, two or four streams of TDM voice, video and data traffic, with associated timing and signaling, across Ethernet, IP and MPLS networks. Zarlink already offers a line of higher-density CES-over-Packet processors that handle from one to 32 streams of TDM traffic.



The new devices could be use in a CES-over-Packet-enabled remote concentrator located at the customer site or a roadside pedestal. TDM traffic would be emulated across a converged packet network. Zarlink said mobile service operators ,who previously relied on expensive T1/E1 leased lines to backhaul traffic from the cell site, could also use the technology to emulate TDM traffic over a more cost-effective fiber or microwave Ethernet link.



Zarlink recently announced that four equipment manufacturers in the U.S. and Korea - Comtec Systems, Eagle Telephonics, Intronics Inc. and Rivertree Networks - are responding to user demand by designing Zarlink CES-over-Packet processors into new media gateways, Central Office and Ethernet switching products that transport TDM services over packet networks. http://cesop.zarlink.com
