MT9074
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 S
bits and channel 16 (E1 mode). The LIU
a
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.
