Description
The MT90866 Digital Switch provides switching
capacities of 4,096 x 2,432 channels between
backplane and local streams, 2,432 x 2,432 channels
among local streams and 2,048 x 2,048 channels
among backplane streams. The local connected serial
inputs and outputs have 32, 64 and 128 64 kb/s
channels per frame with data rates of 2.048, 4.096 and
8.192 Mb/s respectively. The backplane connected
serial inputs and outputs have 128 and 256 64 kb/s
channels per frame with data rates of 8.192 and
16.384 Mb/s respectively.
