Low quality clock sources that deviate from the nominal value cause problems in the operation of network elements. It
is necessary and recommended to measure the signal frequency at all hierarchies to reduce synchronization risks. To
measure line frequency in service, the test set must be connected to a Protected Monitoring Point (PMP). The
frequency of the signal is normally reported in Hz, while the deviation is reported in ppm. Tolerances for the various
clock frequencies of SONET hierarchies are presented in the table below
Level: Measures the Peak and Peak-Peak voltage values of the incoming signal. The levels for STS-3 electrical signal
according to GR.253 recommendations are presented.
