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.Other References
