Model 3120 RAS Getting Started Guide 2 • Hardware installation
Connecting to the T1/E1/PRI WAN ports
An active T1/E1/PRI is not necessary to configure the RAS. However, an active T1/E1/PRI connection is
required to receive or make calls. The factory-set default configuration of the access server has the T1/E1 ports
disabled.
Note The cable connecting the T1/E1/PRI WAN ports to the RJ-48C ter-
mination jack should be CAT-3 or higher and extend no farther than
1 mile from the digital services termination.
1. Refer to figure 12 for the T1/E1/PRI RJ-48C pinout diagram.
Figure 12. T1/E1/PRI RJ-48C pinout diagram
2. Attach the network cable from the telephone network demarc to the Primary T1/E1/PRI port (RJ-48C)
on the RAS.
Note For 75-ohm twin-coax E1 connections, use the Patton Model 460
E1 120-ohm/75-ohm adapter to convert from a 75-ohm dual-coax to
the 120-ohm twisted-pair interface the RAS uses.
Completing the hardware installation
This section verifies that the RAS hardware is operational to the point where you can begin configuring the
software settings.
1. Verify that the AC power cord included with your RAS is compatible with local standards. If it is not, refer to
Chapter 6, “Contacting Patton for assistance” to find out how to replace it with a compatible power cord.
The RAS power supply can be configured for 115 or 230 VAC
operation. By default, the 3120/120 RAS is set to 230 VAC
and the 3120/96 is set to 115 VAC. If you need to change the
voltage setting for your power supplies, contact your Patton dis-
tributor or Patton Electronics technical support.
Verify that the proper voltage is present before plugging the
power cord into the receptacle. Failure to do so could result in
equipment damage.
