Polycom RealPresence Collaboration Server (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.
