Method and apparatus for monitoring the filling factor of the elastic buffer memory in a digital telecommunication system synchronization

摘要

The invention relates to a method and an equipment for monitoring the fill rate of an elastic buffer memory used in a synchronous digital telecommunication system, such as the SDH or SONET system. To enable the monitoring of the fill rate of the channels with less hardware than previously, the fill rate of at least two channels of the same level of hierarchy is monitored on a time-division basis in a monitoring unit (64) common to said channels.
