ABSTRACT:
Time-slot interchange (TSI) switches include a data memory having first entries therein that contain serial data received by the switch and a connection memory having second entries therein. When programmed, these second entries contain addresses of a plurality of the first entries in the data memory and switching modes that have been assigned to the plurality of the first entries. A control circuit is also provided to automatically program a block of the second entries in the connection memory with updated switching modes during an efficient burst program mode of operation. An internal bypass feature is also provided to support efficient testing/debugging of downstream devices in a communications path.
