Description
The MT9075A is a single chip device which integrates an advanced PCM 30 framer with a Line Interface Unit (LIU). The framer interfaces to a 2.048 Mbit/s backplane and provides selectable rate data link access with optional HDLC controllers for Sa bits and channel 16. The LIU interfaces the framer functions to the PCM 30 transformer-isolated four wire line. The MT9075A meets or supports the latest ITU-T Recom...
