Abstract
Time-slot interchange (TSI) switches include an input buffer that is configured to receive at least first and second groups of serial input data streams and an output driver that is configured to generate at least first and second groups of serial output data streams. A control circuit is also provided. This control circuit is electrically coupled to the input buffer and output driver. The control circuit is configured to provide programmable group-based output drive enable control to the at least first and second groups of serial output data streams that is independent of per-channel output stream programming. This per-channel output stream programming is defined by mode bits within the switch's connection memory.
