Proactive isolation of telecommunication faults based on alarm indicators

Abstract

Methods, systems, and apparatuses, among other things, may integrate one or more first alarms reported by routers and Ethernet switches with one or more second alarms reported by reconfigurable optical add/drop multiplexers (ROADMs) and optical transport network (OTN) network elements. Moreover, one or more troubleshooting actions may be performed based on the integrated first alarms and second alarms.
