  • Line Monitoring for SDH signals
    Patent number: 5432796
    Abstract: Regenerator sections in known regenerators, which comply with CCITT-Recommendation G.958, are supervised by monitoring the transmission error probability of SDH (synchronous digital hierarchy) signals, through determination of the parity. This requires the breakdown and restoration of the SDH signal. This requires special signal processing installations, not required for regenerating transmission signals, such as multiplexer and demultiplexer, which cause considerable loss of output. The regenerator (RE) according to the invention determines the transmission error probability by comparing a known word in the head part of an STM-N signal with a reference word. The transmission error probability is derived from the result of the comparison, and transmitted to a central unit via an error line (FL). For example, to transmit the transmission error probability in an STM-N signal, the service channel of a regenerator that complies with CCITT-Recommendation G.958 may be used.
