RTM ISDN

The RTM ISDN card connects directly to an MPM+/MPMx. The RTM ISDN card routes data between the MPM+/MPMx cards and components of the system, converts ISDN T1/E1 media to IP packets and provides connectivity to external ISDN networks.

The RTM ISDN card is installed on the rear panel of the RMX interfaces between the RMX unit and the ISDN/PSTN switch. Up to two RTM ISDN

cards can be installed in one RMX 4000

In an RMX with a single MPM+/MPMx card – the RTM ISDN card must be installed in a rear panel slot at the same level as the MPM+/ MPMx card

In an RMX with two MPM+/MPMx cards – the RTM ISDN card can be installed in any of the rear panel card slots. Up to a total of 14 E1 or 18 T1 PRI cables can be installed with two MPM+/MPMx and RTM ISDN cards
