Description
The ZL50031 Digital Switch provides switching
capacities of 4,096 x 2,048 channels between
backplane and local streams, 2,048 x 2,048 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 kbps
channels per frame with data rates of 2.048, 4.096 and
8.192 Mbps respectively. The backplane connected
serial inputs and outputs have 128 and 256 64 kbps
channels per frame with data rates of 8.192 and
16.384 Mbps respectively.
