PQL Configuration


The PQL Configuration screen provides information on PQL settings.

PQLs allow the system to compare and rate the signal quality from different sources, and provide an effective way for it to communicate the quality of output signals. SSM to PQL translation is performed by the input when SSM signals are received. The PQL to SSM translation is performed by the DS1/E1 output when SSMs are generated.

Click Edit to change the PQL configuration.

Note: Normally, editing the PQL table is not necessary. Edits may be required, however, if ANSI or ITU-T SSM standards are changed.

The table below provides factory default PQL settings.
