Abstract
Abstract Monitoring apparatus is disclosed for monitoring the operating condition of transmission facilities of communications transmission technology, whereby signal collectors (stations) of a signal collecting device collect trouble reports acquired in monitoring the transmission. The monitoring apparatus should collect trouble reports in as economical a manner as possible and should keep further criteria for the quality of the monitored transmission devices ready for interrogation, as needed. This is achieved by a monitoring apparatus having an evalution and memory device which periodically registers measured values. The measuring device can be advantageously employed for monitoring line terminal equipment in PCM transmission facilities.

Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
121 words
In an in-service monitoring apparatus for monitoring the operational condition of transmission facilities of communications transmission technology which are composed of assemblies for transmitting and receiving signals, the monitoring apparatus having a monitoring device that acquires both trouble reports and measured values and that includes a monitoring information generator which is connectable, together with monitoring information generators of other monitoring devices, to signal receivers of a signal collecting apparatus for certain operations observations, and having an evaluation and memory device in said monitoring device in which the measured values are periodically acquired and edited, the improvement comprising: means for registering said acquired and edited measured values with said memory device such that the memory contents are overwritten in a cyclic manner.
Claim 2
Dependent Claim
121 words
