INTEGRATED MULTI-FABRIC DIGITAL CROSS-CONNECT INTEGRATED OFFICE LINKS

摘要

An integrated multiple cross-connect system (10) having remotely located components interconnected by integrated office links (34, 36, 40) is provided. The integrated office link (34, 36, 40) carry duplex transmission of an IOL-N signal of N multiplexed STS-1P optical signals at an OC-N rate, the STS-1P include data payload and overhead field. Fault coverage information in the IOL overhead field are monitored at selected points along a transmission path. Upon detecting a fault, all the monitors in the transmission path are enabled to monitor the IOL overhead fault coverage information to isolate the origin of the detected fault.
