Adtran Atlas 550 4 Channel Voice Compression Module 1200312L5by Adtran
Adtran Atlas 550 4 Channel Voice Compression Module 1200312L5 Description:
The Atlas 550 voice compression module (1200312L5) performs G.723.1 compression for four voice channels in frame relay applications. The card allows for four calls to feature compressed audio in order to save bandwidth. The card does not present any physical interfaces and is a plug-on board for all user interface modules and the resource host module. By using only 1/6th the bandwidth of a standard phone call, the voice compression module allows up to 6 calls to be made on a single DS0 circuit.
The 1200312L5 allows for up to 4 channels to utilize the G.723.1 voice codec. The 1200312L5 is only supported in Adtran Atlas 550 gateways.
