Method for manifesting alarm in telecommunication network

A method and a Network Element (NE) for manifesting alarms by forming a so called combined Data Quality Byte (DQB) for a particular SDH/SONET data transmission stream. The DQB indicates status of alarms at a particular location of the telecommunication network, via which the stream is transmitted. T...

Zusammenfassung:	A method and a Network Element (NE) for manifesting alarms by forming a so called combined Data Quality Byte (DQB) for a particular SDH/SONET data transmission stream. The DQB indicates status of alarms at a particular location of the telecommunication network, via which the stream is transmitted. The DQB can be formed by arranging a plurality of alarm signals, currently actual for the particular data transmission stream, in a predetermined byte associated with the stream frame. The NE, upon receiving from an upstream network element a data transmission stream with its DQB 1 formed upstream, creates an updated DQB 2 and compares DQB 1 with DQB 2 to manifest an alarm status change DeltaDQB for estimating quality of transmission via the network section.
