Select "Synchronization" -> "Modify Synchronization Outgoing"
Check that the "free-running" indication is present in the timing reference block
•
dedicated to the internal oscillator G.783. If the "Hold-Over" indication is displayed,
first switch the equipment off and then back on again. Afterwards repeat all the
procedures.

Select "Synchronization" -> "Modify Synchronization Switch"
Check that the frequency counter reads a measured value of 2048 kHz ±4.6 ppm. To
•
perform this measure, the "Squelch T0/T4" must be deactivated (green color), by
selecting Synchronization -> T4 Configuration; in "Squelch T0/T4" field, set T0 =

Connect the outgoing synchronism to the frequency counter
Enter ED-BITS-

OUT:[TID]::[CTAG]:::[,LINECDE=][,FMT=][,ESFTRANS=];
in order to verify that no reference has been selected for each Timing Reference block
except for the internal oscillator block "G.813." Protocol G.813 local synchronization
level. To make the test set G.813 instead of G.811. Access the synchronization menu
and click on T4 modification, a T0 and T4 window will appear. Set G.813. On the
contrary remove all the timing reference source from each Timing Reference blocking
as follows:
Enter ED-SYNCN-OUT /PRIOREFA / SECOREFA
Enter OPR-SYNCNSW /SWITCHTO
