Zarlink Semiconductor Inc. said today it plans to release a network access processor designed to solve capacity bottlenecks in network access equipment later this fall.
"Steady growth in profitable TDM-based voice and data services, such as T1/E1 leased lines, is resulting in switching bottlenecks in today’s access and aggregation equipment," the Ottawa company said in a statement. "These bottlenecks stem from capacity limits in TDM cross-point switches, or backplanes, which are difficult and expensive to scale. To overcome the limitations, many equipment companies are designing Ethernet switching backplanes into next-generation access systems. These Ethernet backplanes have higher capacities, are easier to scale, and cost less than TDM backplanes."
Zarlink’s new device, currently under development, is the industry’s first purpose-built processor to support next-generation Ethernet backplanes, the company said.
"The processor uses patent-pending software to overcome technical issues with TDM timing and synchronization," it said. "This capability, coupled with the low processing latency (delay) of the device, allows TDM channels to cross-connect over switched Ethernet networks either individually or in trunked Nx64 Kb/s (kilobit-per-second) configurations with the same carrier-grade quality delivered by TDM backplanes."
Zarlink customers are now testing samples of the new processor for design into a range of next-generation access and aggregation equipment, including telephony switches, multi-service access platforms, and voice-over-IP (Internet Protocol) gateways.
