The TNETV266x VoIP gateway solution integrates Telogy Software™ with TI’s industry-leading TMS320C64x+™ core to provide a low cost, scalable, voice-only solution that can provide from eight to 28 or more G.711 channels with a 128ms echo canceller tail. Using the MII interface and an external Ethernet switch, the TNETV266x can be scaled to provide options that meet multiple product configurations.

In addition to the high-performance C64x+™ core, the TNETV266x devices offer a DDR2 external memory interface for faster memory accesses as well as all of the required system interfaces for simpler designs. The two pin-compatible TNETV266x devices (the TNETV2664 and the TNETV2666 devices) offer solutions at the density level needed for gateway products. Supported codecs include G.711, G.726, G.729AB, G.723.1A, G.722 and iLBC.
