.

With the RMX 4000, you can either have a dedicated E1 or T1 Type Network

Service. It is not possible to have a mixed E1 and T1 ISDN Network Service.

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.

RTM LAN

The RTM LAN card routes data between the MPM+/MPMx cards and components of the system, sends media by IP packets and provides connectivity to external networks.

An RTM LAN card must connect directly to an MPM+/MPMx card. In an RMX with a single MPM+/MPMx card, the RTM LAN card must be installed in the rear panel slot on the same level as the MPM+/MPMx card.

Each RTM LAN card includes 2 LAN ports and a maximum of four RTM LAN cards can be installed on the RMX 4000.
