SHELTON, Conn. -- TranSwitch Corp. here today announced a complete OC-3 through OC-48 chip for processing mixed TDM, ATM, and PPP payloads over Sonet/SDH.
The PHAST-12 VLSI device is targeted at OEMs that need to reduce their time-to-market and expand their design options in constructing multi-service access and transport products. The PHAST-12 is designed to eliminate the multiple devices required to implement complex Sonet/SDH termination applications.
PHAST-12 supports TDM, ATM, and PPP on the terminal side while supporting OC-3, OC-12, and channelized OC-48 on the line side. This enables designers to use the chip for a wide range of applications. For example, in conjunction with the TranSwitch family of mapper devices, the PHAST-12 can support TDM, while simultaneously supporting ATM/PPP (cell/packet) traffic.
This high level of functional integration on a single chip -- including on-chip cross-connect to support Automatic Protection Switching (APS) -- is an advantage for OEMs in both time-to-market and board space, the company said. Earlier solutions required multiple devices and extensive glue logic to attain the same breadth of function in complex applications such as multi-service add/drop multiplexers, switches, routers, concentrators and central office cross connects.
The PHAST-12 VLSI device is available in one thousand unit sample quantities at $198 each. The PHAST-12 comes in a 474-lead ball grid array (BGA) package.
