ISDN/PSTN Clock Source

Each RTM ISDN card 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.
All external connectors are located on the rear panel.
