Embedded SDK for 8-Line Analog PCI Board
Commetrex Releases Version 1.0 of MSP-H8 SDK

For Immediate Release

Roswell, GA, January 31, 2003 – Commetrex Corporation has released the Embedded SDK for its MSP-H8 8-line PCI analog telephony interface. The board gives OEMs a low-cost high- performance one-to-8 line PCI board available with either FXS or FXO interfaces. The SDK, which includes source code for an NT driver, supports the development of board-level applications, but Commetrex points out that it uses the board internally as a PCM interface for host-based signal processing.

According to Ben Feldgajer, Director, Embedded Systems, at Commetrex: “The SDK includes all the board-level runtime software, as well as our I/O driver and all the support software we developed for internal use. Also included is a comprehensive subsystem that manages the various analog trunk protocols, giving the user of the included driver a complete system for call control.”

“We use the on-board TI TMS320C5402 DSP to decimate the 16-KBPS codec’s sample rate to 8K and to compensate for the roll off of the low-noise sigma-delta converter. This gives the stream-processing software an extremely low-noise, high-accuracy signal, suitable for any telephony application, including high-bit rate data modems,” Feldgajer added.

The MSP-H8 includes up to 8 pluggable line interfaces that meet the homologation requirements of Japan, North America, and the ETSI CTR-21 requirement. The board’s ‘C5402 DSP’s internal RAM is augmented by 128-Kbytes of 10-nanosecond static RAM. These resources make the MSP-H8 suitable for any low-density telephony application, including media servers, PSTN-IP gateways, or IADs.

The MSP-H8 Embedded SDK (PN-70005) is $3,450, with no royalty payments. The MSP-H8 is $295.00 and each line interface is $48.00. The OpenMedia™ for MSP SDK (PN 20112), priced at $3,850, allows the OEM to add proprietary or Commetrex-provided media technologies without having to develop a streams framework.
