| 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). The framer interfaces to a 2.048 Mbps 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 PCM 30 (E1 mode) transformer-isolated four-wire line with minimal external components required. |

Features & Benefits
- Combined E1 (PCM 30) and T1 (D4/ESF) framer, Line Interface Unit (LIU) and link controller with optional digital framer only mode
- In T1 mode the LIU can recover signals attenuated by up to 30 dB (5000 ft. of 24 AWG cable)
- In E1 mode the LIU can recover signals attenuated by up to 30 dB (1900 m. of 0.65 mm cable)
- Two HDLCs: FDL and channel 24 in T1 mode, timeslot 0 (Sa bits) and timeslot 16 in E1 mode
- Two-frame elastic buffer in Rx & Tx (T1) directions
- Programmable transmit delay through transmit slip buffer
- Low jitter DPLL for clock generation
- Enhanced alarms, performance monitoring and error insertion functions
- Intel or Motorola non-multiplexed parallel microprocessor interface
- ST-BUS 2.048 Mbps backplane bus for both data and signaling
- Japan Telecom J1 Framing and Yellow Alarm
- Hardware data link access
- JTAG Boundary Scan
