Zarlink processor allows TDM switch replacement

Zarlink Semiconductor has announced that they are developing a carrier-quality network access processor that can solve capacity bottlenecks in access equipment by allowing Ethernet switches to replace traditional TDM switching backplanes.

The company claims that 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 Nx64Kbps configurations - with the same carrier-grade quality delivered by TDM backplanes.

Designed to support next-generation Ethernet backplanes, the process uses patent-pending software to overcome technical issues with TDM timing and synchronization. The Ethernet backplanes enabled by the new processor will allow network operators to accommodate growing levels of TDM service traffic quickly, easily, and cost-effectively by simply adding new line cards to access and aggregation equipment.

"Zarlink's new network access processor meets customer demand for devices that support low-cost, high-capacity, carrier-grade TDM access switching," said Jeremy Lewis, product line manager, Zarlink Semiconductor. "The Ethernet system architecture enabled by our new device will allow next-generation access equipment to easily and cost-effectively scale beyond OC-12 rates."

The new device features a power-efficient engine that simultaneously converts up to 32 T1/E1 lines or 1,024 TDM circuits, into Ethernet packets. Regardless of the number of channels being processed, the device is claimed to introduce 2505s of packet processing latency.

The processor also suits other network convergence applications, including circuit emulation services over packet (CESoP) and offloading TDM data services to remote access concentrators.
