Model 9102A E1 2:1 transcoder converts two 30-channel E1 PCM streams into one 60-channel ADPCM composite stream. Applications include long distance, cellular, mobile radio, satellite, and private networks. The 9102A incorporates the ADPCM algorithm, as well as an enhanced ADPCM algorithm that allows 9.6 kbps in-band modem traffic and Group III facsimile to be passed on compressed channels. The 1.75 x 19 x 15.75-inch unit can be programmed from the front panel with the alphanumeric display or by remote terminal through the EIA-232-D port.
