摘要: A digital cross connect system includes reception interface parts for converting an input line signal into a VT having frame format in conformance with synchronous optical network (SONET) standards, switching part connecting the received from parts, and transmission connected signal. The inserts synchronizing within reserved path overhead of signal, achieves synchronization response to
