Data Sheet

Description

The MT9074 is a single chip device, operable in either T1 or E1 mode, integrating either an advanced T1 (T1 mode)

or PCM30 (E1 mode) framer with a Line Interface Unit (LIU).

The framer interfaces to a 2.048 Mbit/s backplane providing selectable data link access with optional HDLC

controllers for either the FDL bits and channel 24 (T1 mode) or Sa bits and channel 16 (E1 mode). The LIU

interfaces the framer to T1 (T1 mode) or PCM30 (E1 mode) transformer-isolated four-wire line with minimal

external components required.

In T1 mode, the MT9074 supports D4, ESF and SLC-96 formats, meeting the latest recommendations including

ITU I.431, AT&T PUB43801, TR-62411, ANSI T1.102, T1.403 and T1.408. In E1 mode the MT9074 supports the

latest ITU-T Recommendations including G.703, G.704, G.706, G.732, G.775, G.796, G.823 for PCM30, and I.431

for ISDN primary rate. It also supports ETSI ETS 300 011, ETS 300 166 and ETS 300 233.
