Description
The MT8985 Enhanced Digital Switch device is an upgraded version of the popular MT8980D Digital Switch (DX). It is pin compatible with the MT8980D and retains all of the MT8980Ds functionality. This VLSI device is designed for switching PCM-encoded voice or data, under microprocessor control, in digital exchanges, PBXs and any ST-BUS/MVIP environment.
Features
• 256 x 256 channel non-blocking switch
• Programmable frame integrity for wideband channels
• Automatic identification of ST-BUS/GCI interface backplanes
• Per channel tristate control
• Patented message mode
• Non-multiplexed microprocessor interface
• Single +5 volt supply
• Available in DIP-40, PLCC-44 and QFP-44 packages
• Pin compatible with MT8980 device
Applications
• Medium size digital switch matrices
• Hyperchannel switching (e.g., ISDN H0)
• ST-BUS/MVIP™interface functions
• Serial bus control and monitoring
• Centralized voice processing systems
• Data multiplexer
