5.0 OPERATION
Once the Model IM2RC/F is installed and configured, it should
operate transparently. This sections describes a typical application
and general operating instructions.
5.1 TYPICAL APPLICATION
The Model IM2RC/F allows a remotely connected LAN or high
speed application to connect to the 64k/G.703 (PCM) network through
a pair of Patton baseband modems. Figure 8 (below) shows a typical
application of the IM2RC/F.
5.2 OPERATING INSTRUCTIONS
In order to operate, the Model IM2RC/F must be installed in the
rear of a Patton 16 port rack or a 2, 4, or 8 port ClusterBox™ chassis.
A front function card, such as a baseband modem, CSU/DSU, or HDSL
modem meets the IM2RC/F rear card in the mid-plane of the chassis.
The IM2RC/F also requires a G.703 connection to the 64 kbps co-
directional PCM network and a line connection to a remote Patton
transmssion device. After applying power, the function card and
IM2RC/F operate transparently according to the applied settings
(Please refer to the function card manual for further details).

NOTE:
The pin designations shown above are to be used when
connecting to another IM2RC/F or other similarly pinned line
interface on a Patton rear card. Please review the appropriate
function card user manual or stand-alone product user manual to
determine the correct pin assignments.

Notice!
Any G.703 or line interface cable connected to the
Model IM2RC/F must be shielded cable, and the outer shield
must be 360 degree bonded–at both ends–to a metal or
metalized backshell.
