About the Cisco IPVC 3540 PRI Gateway

The Cisco IPVC 3540 PRI Gateway consists of two modules that insert into a Cisco IPVC 3544 chassis:
the Cisco IPVC 3540 PRI Gateway module and the Rear Transition Module (RTM). The gateway
module installs in the front of the chassis and contains the gateway application apparatus. The RTM
installs in the rear of the chassis and contains the physical interface that connects to the PRI-service
provider equipment. You must install the gateway module and the RTM in corresponding slots. For
example, if you install the gateway module in slot 2 in the front of the chassis, you must install the RTM
in slot 2 in the rear of the chassis.
The Cisco IPVC 3544 chassis requires that the module installed in the top slot provide the system
controls for the cPCI bus. The gateway module has system capability, and can be installed in top slot of
the chassis or in one of the other slots. When you install a gateway module in the top slot, you must
replace the original RTM in the top slot in the rear of the chassis with a gateway RTM.
