•

In T1 mode the LIU can recover signals attenuated

by up to 36 dB (6000 ft. of 24 AWG cable)

-40°C to 85°C

In E1 mode the LIU can recover signals attenuated

by up to 36 dB (2000 m. of 0.65mm cable)

Description

The MT9074 is a single chip device, operable in

either T1 or E1 mode, integrating either an advanced

T1 (T1 mode) or PCM 30 (E1 mode) framer with a

Line Interface Unit (LIU).

Two HDLCs: FDL and channel 24 in T1 mode,

timeslot 0 (Sa bits) and timeslot 16 in E1 mode

buffer

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

•

Low jitter DPLL for clock generation

Enhanced alarms, performance monitoring and

error insertion functions

24 (T1 mode) or S bits and channel 16 (E1 mode).

The LIU interfaces the framer to T1 (T1 mode) or

PCM 30 (E1 mode) transformer-isolated four-wire

line with minimal external components required.

•

Intel or Motorola non-multiplexed parallel

microprocessor interface

ST-BUS 2.048 Mbit/s backplane bus for both data

and signaling

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
