The MT8950 is a coder/decoder which uses the Transition Encoded Modulation (TEM) technique for encoding/decoding low speed data to and from a 56/ 64 kbps channel (equivalent to PCM Voice). The coding and decoding scheme is transparent and can accept either synchronous or asynchronous data up to 8 kbps (inclusive); at 9.6 kbps and 19.2 kbps. The MT8950 is fabricated in MITEL's ISO-CMOS technology.
