Commetrex Adds Optimized Version Of G.729a/b To OpenEndpoint
Developers of an endpoint gateway targeting the small to mid-size enterprise, which typically requires POTS-line interfaces, will benefit from Commetrex' latest upgrade of OpenEndpoint. OpenEndpoint, an IP-endpoint licensed-technology suite, now includes a highly optimized
implementation of the G.729a/b voice coder (vocoder) for the Texas Instruments (TI) TMS320C6200 generation of DSPs.
G.729a/b is the ITU recommendation for a vocoder that compresses 64-Kbps speech to 8-Kbps. Commetrex' G.729a/b requires only 10 MCPS for duplex operation on a TMS320C62x DSP. Commetrex has previously shipped OpenEndpoint with support for G.711, G.726, and G.723.1.
The OpenEndpoint algorithms are available in C and 'C6000 assembly code. They are also available in TI eXpressDSP and MSP Consortium M.100 versions. A single low-cost 200-MHz TMS320C6000 DSP provides, for example, 12 non-blocking
channels running G.729a/b with OpenEndpoint's echo canceller.
"We're pleased that Commetrex has delivered to the telecom sector an even more comprehensive version of OpenEndpoint by adding G.729a/b," says Marc Wallace, TI's worldwide third-party program manager. "Commetrex' G.729a/b is eXpressDSP compliant, which means an added degree of testing has been completed through TI's compliance program."
Cliff Schornak, Commetrex' CTO explains: "Commetrex' ongoing efforts to help equipment developers avoid investing more time and money than necessary in their new products led to our development of OpenEndpoint optimized for the 'C6000.
OpenEndpoint will give developers a true advantage when developing voice-fax IP endpoint devices, especially if the product requires a POTS interface.
Commetrex has been steadily building its portfolio of IP-gateway technologies. But with the completion of the OpenMedia streams framework, the MSP-H8 8-line analog PCI card, its G.168-compliant echo canceller, and now a highly optimized version of G.729a/b, the Company has assembled all the elements required for a complete voice-fax endpoint.
