摘要: A cross-connection apparatus for B-ISDN includes plural interface units, multiplexers, virtual path identifier (VPI) conversion tables, demultiplexers, and loop-back units a switch unit. The unit has reception port receiving an ATM cell or inserting monitor cell, transmission transferring the extracting cell; multiplexer is operatively connected to corresponding multiplexing VPI tables converting change route of switching based on VPI; demultiplexer demultiplexing port; changing so as transfer same which inserted, result, can be monitored by comparing inserted with extracted in
