A method and arrangement for the transmission of quality criteria of a synchronous network hierarchy

摘要

A method for the transmission of quality criteria (tqk) of a plurality of tributary - signals (stm - m₁, Stm - m₂, ...) a synchronous network hierarchy (sdh / sonet), the higher order to form a multiplex signal (stm - n) and combined in a transport module (stm - n) of higher order are transmitted via a synchronous network,characterized by the,that the tributary - signals (stm - m₁, Stm - m₂, ...) to be monitored,in such a way that different tributary - quality criteria (tqk1, tqk2,...) via the state of each of the tributary - signals (stm - m₁, Stm - m₂, ...) to be generated,that the tributary - quality criteria (tqk1, tqk2,...) of each of the tributary - signals (stm - m₁, Stm - m₂, ...) in each case to a monitoring combination (fdi1, fdi2,...) are combined andthat the monitoring combinations (fdi1, fdi2,...) to be transmitted in the overhead of the transport module (stm - n) of higher order are inserted.
