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 S

The LIU interfaces the framer functions to the PCM

30 transformer-isolated four wire line.

The MT9075A meets or supports the latest ITU-T

Recommendations including G.703, G.704, G.706,

G.732, G.775, G.796, G.823 for PCM 30, and I.431

for ISDN primary rate. It also meets or supports ETSI

ETS 300 166 and BS 6450.
