Polycom RMX 1500 Hardware Guide
ISDN/PSTN Clock Source
Each RTM ISDN 1500 has its own primary and secondary clock source. The first span to synchronize becomes the primary clock source and the second span to synchronize becomes the secondary clock source. This clock is used to synchronize ISDN spans only (it is not the system clock).
A single clock source triggers an alarm that can be turned off by setting the appropriate flag in the system configuration.
