The 7290820 is a non-blocking digital switch that has a capacity of 2,048 x 2,048 channels at a serial bit rate of 8.192Mb/s, 1,024 x 1,024 channels at 4.096Mb/s, and 512 x 512 channels at 2.048Mb/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. The 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.
