VoIP and VoATM building blocks cut network costs

Motorola Computer Group has launched two high-density ComStruct VoIP/VoATM building blocks designed to drive the convergence of voice and data telecomms networks.

Motorola Computer Group has launched two high-density ComStruct VoIP/VoATM building blocks designed to drive the convergence of voice and data telecomms networks.

With its carrier-grade PVRB672 packet voice resource board and PVRM672 module, Motorola aims to accelerate the deployment of converged network media gateways by enabling OEMs to significantly reduce their cost per channel and power consumption in an open standard architecture that uses less space.

The new ComStruct building blocks - each engineered to deliver up to 672 compressed voice channels for VoIP/VoATM with field-proven, long tail length echo cancellation - are designed to meet the needs of OEM applications such as trunking and wireless media gateways, enterprise/campus toll bypass gateways, digital local loop and class 5 switch replacement.

The ComStruct PVRM672 is a PT3MC compatible 'media gateway on a module' which combines a network processor and DSP array enabling OEMs to increase channel capacity and add field proven media processing capabilities to existing or proprietary systems.

The ComStruct PVRB672 is a CompactPCI blade that adds physical PSTN, IP and ATM connectors, including CompactPCI packet switched backplane (PICMG 2.16) connectivity, to the media gateway functionality.

Both building blocks are differentiated by powerful software: FACT-MG is Motorola's high-level software environment that abstracts a customer's application from the underlying packet voice hardware resources and is designed to speed time to market and help reduce risk.

"Cost per channel is king in the converged network and these ComStruct building blocks can help to slash per port pricing that OEMs can get on an outsourced platform.

Carrier-grade VoIP technology is now generally accepted as technically stable so breaking new ground in cost per port will make the operator's decision on whether to deploy an IP network much easier", said Nigel Forrester, product manager, Motorola Computer Group.

"The processing power and range of connectivity on these building blocks also makes them ideal for the growing number of customers wanting to build 'universal hardware platforms' for their various converged network applications.

They've recognised that a common architecture across products can really speed time to market - and there's very few suppliers out there that can provide all the pieces of the puzzle".

Both ComStruct building blocks feature a network processor, which consists of a RISC-based microprocessor element and a number of data engines enabling wire speed operation.

This processing power enables Motorola's customers to apply Quality of Service standards within their application.

The network processor also enables the ComStruct building blocks to handle various network protocols such as IPv6, IPv4 and ATM, and so provides customers with the flexibility to tailor the ComStruct solution to their specific network requirements.

With an array of optimised DSPs for voice resources and powerful on-board control processing, both building blocks can function as standalone media gateway platforms.

The PVRB672 can operate as a self-contained media gateway blade within a CompactPCI chassis.

The PVRM672 requires no intelligence on a carrier board to initialise and so can operate as a complete 'plug on media gateway'.

The new ComStruct building blocks are each engineered to provide 672 channels of G.729AB compressed voice with 128ms echo cancellation over IP or ATM encapsulation, and up 1008 G.711 uncompressed voice channels.

Both new ComStruct VoIP/VoATM building blocks are expected to be available in Q3 2002 at a cost of below $10 per port for OEM volumes.
