Allentown, PA - October 30, 2000 - Lucent Technologies Microelectronics Group today introduced the Lucent Voice Packet Processor (VPP), the newest member of the Lucent "Payloadplus" family of network processors. The VPP is an asynchronous transfer mode adaptation layer 2 (AAL-2) co-processor designed to work with the Lucent Fast Pattern Processor (FPP) and the Routing Switch Processor (RSP).
"Our VPP is an example of the advantages that our modular, building block approach brings to network processors," said Jim Johnston, network processor marketing director with Lucent's Microelectronics Group. "Our network equipment customers told us they wanted to implement AAL-2 voice processing in their voice and data gateways. By adding the VPP to our Payloadplus solution, they can have a powerful, elegant solution to a very difficult problem - the convergence of voice and data."
"This product supersedes currently available solutions - it supports over 32,000 conversations at up to OC-12 rates in a diverse multiprotocol environment," said Juan Garza, VPP marketing manager with Lucent's Microelectronics Group. "The design of the VPP enables engineers to design systems that are compatible with circuit-switched voice telephone networks and provide POTS-level voice quality. It can also manage high-speed data flow through a common gateway."
Voice Packet Processor (VPP) is an AAL-2 co-processor designed to take advantage of the classification power of the Lucent FPP and the routing and switching capabilities of the Lucent RSP. AAL-2 is a standards layer that translates higher layer services into the size and format of an ATM cell. AAL-2 functions in support of constant-bit-rate and variable-bit-rate real-time traffic, such as voice, that are sensitive to delays.
In a typical configuration, the VPP is connected between the FPP's packet-over-SONET physical layer (POS-PHY) output and the RSP's POS-PHY input in the wire-speed data path. Traffic not requiring AAL2 processing is passed transparently by the VPP to the RSP. Traffic requiring AAL-2 processing is identified by the FPP and processed by the VPP. Results processed by the VPP are then sent to the RSP for final traffic handling.
The software development environment (SDE) to support the Lucent Voice Packet Processor is available immediately. Chip samples are slated for availability in the second quarter of 2001.
