512 x 256 Channels Multiple Rate Digital Switch (MRDX) with constant delay mode

Product Detail

The Multiple Rate Digital Switch (MRDX) is an upgraded version of the MT8980D Digital Switch (DX). It is pin compatible with the MT8980D and retains all of its functionality. This device is designed to provide simultaneous connections (non-blocking) for up to 256 64 kps channels or blocking connections for up to 512 64 kbps channels. The serial inputs and outputs connected to MT8986 may have 32 to 128 64 kbps channels per frame with data rates ranging from 2048 up to 8192 kbps. The MT8986 provides per-channel selection between variable and constant throughput delays allowing voice and grouped data channels to be switched without corrupting the data sequence integrity. In addition, the MT8986 can be used for switching of 32 kbps channels in ADPCM applications. The MT8986 is ideal for medium size mixed voice and data switching/processing applications.
