Patton electronic IM2RC/F Two-Wire and Four-Wire Cable Connection Via RJ-45, Signal, Pin#

4.3.3Two-Wire and Four-Wire Cable Connection Via RJ-45

1.The Line Interface Port on the Model IM2RC/F’s twisted pair interface is polarity insensitive and is wired for a two-wire interface.

2.Proper 2-Wire Pairing between the two modems is as follows:

SIGNAL	PIN#	PIN#	SIGNAL
TIP	4---------------------------------------------	4	TIP
RING	5---------------------------------------------	5	RING

3. Proper 4-Wire Pairing between the two modems is as follows:

SIGNAL	PIN#	PIN#	SIGNAL
Tx	4---------------------------------------------	3	Rx
Tx	5---------------------------------------------	6	Rx
Rx	3---------------------------------------------	4	Tx
Rx	6---------------------------------------------	5	Tx

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.

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).
