I have a Rmx 4000 which have major Alarm,it showing the " RTMISDN no clock source " major Alarm.
plz help me for the solve out the problem.
welcome to the Polycom Community.
From the RMA4000 Setup and Maintenance guide => here <=
Clock Source – indicates if ISDN signaling synchronization is being supplied by the Primary or Secondary clock source.
The first span to synchronize becomes the Primary clock source.
Is your ISDN Line working ?
Polycom Global Services
I assume you only have one ISDN/PRI line attached, in which case this is a standard error on RMX due to there being no backup clock source
you need to modify system config and add a system flag for single ISDN clock source = YES
Hope that helps
I have a simular concern that maybe the group can help me with.
I have two ISDN lines, but never want the backup to become primary when the primary looses a beat. :> How can I tell the backup to always be backup?
