Description

The MT9085 Parallel Access Circuit (PAC) provides an interface between an 8 bit, parallel time division multiplexed bus and a serial time division multiplexed bus. A single PAC device will accept data clocked out on the parallel bus of the Mitel MT9080 (SMX) and output it on 32/16 time division multiplexed serial bus streams. A second device can be configured to perform the conversion from the serial format into an SMX compatible parallel format. The time division, serial multiplexed streams may operate at 2.048 Mbit/s or at 4.096 Mbit/s. The PAC generates all framing signals required by the SMX for 1024 and 2048 channel configurations.

Features

? Configurable for parallel-to-serial or serial-to-parallel conversion of 1024 channels

? Interfaces to Mitel’s MT9080 Switch Matrix Module (SMX). Generates all framing signals required in 1K or 2K switching applications

? Serial data rates of 2.048 Mbit/s or 4.096 Mbit/s

? Mitel ST-BUS? compatible serial inputs/outputs

Applications

? Interfacing the MT9080 Switch Matrix Module to an ST-BUS system

? Rate conversion between 4 Mbit/s and 2 Mbit/s serial streams

? Interfacing a parallel system bus to devices utilizing serial I/O
