Overview

The 72V70800 is a non-blocking digital switch that has a capacity of 512 x 512 channels at a serial bit rate of 8.192Mb/s. Some of the main features include programmable stream and channel control, Processor mode, input offset delay, and high-impedance output control.

Per-stream input delay control is provided for managing large multi-chip switches that transport both voice channels and concatenated data channels. In addition, input streams can be individually calibrated for input frame offset.

This device is an ST-BUS® compatible digital switch controlled by a microprocessor that can handle from 128 x 128 to 32K x 32K inputs to multiple outputs.

  • 512 x 512 channel non-blocking switching at 8.192Mb/s
  • Per-channel variable or constant throughput delay
  • Automatic identification of ST-BUS®/GCI interfaces
  • Accepts 4 serial data streams of 8.192Mb/s
  • Automatic frame offset delay measurement
