RTM ISDN
The RTM ISDN card connects directly to an MPM card. The RTM ISDN
card routes data between the MPM cards and components of the system,
converts ISDN T1/E1 media to IP packets and provides connectivity to
external ISDN networks. Up to two RTM ISDN cards can be installed in
one RMX 2000.
Each RTM ISDN card includes the following connections:
• 12 E1/T1 PRI lines
•1 LAN port

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.

are T1 or E1.
