RTM ISDN 1500

The RTM ISDN 1500 connects directly to the built-in MPMx. The RTM ISDN card routes data between the MPMx card 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.

With the RMX 1500, 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.

The RTM ISDN card contains four connections to which up to four E1 or T1 PRI lines can be connected as shown in Figure 1-4.
