Chapter 2 Installing the Access Gateway Module

Connecting the Voice and WAN Interface Modules

Figure 2-12 Pinout Convention for the Telco RJ-21

See Table C-3 in Appendix C, “Connector and Cable Specifications” for a mapping of the RJ-21 pinouts

for the 8-port FXS module connector.

Connecting the 2-Port FXO Voice Interface Modules

This section describes how to connect and verify the status of the 2-port FXO voice interface modules

(VIC-2FXO, VIC-2FXO-M1, VIC-2FXO-EU, VIC-2FXO-M2, and VIC-2FXO-M3).

Setting the Jumpers on the 2-Port FXO Module

The 2-port FXO voice interface module includes two jumper headers (W3 and W4) that you can use to

set loop-start or ground-start mode. One jumper configures each FXO port. The default setting is loop

start. In the default setting, jumpers are placed over positions 2 and 3 of headers W3 and W4.

Updated modern CO equipment, such as the DMS-100 and 5ESS switches, provides the CPC and ROS

features on loop-start lines. CPC provides faster disconnection, and ROS minimizes glare (collision of

inbound and outbound calls on the same interface). If your CO does not provide these features on

loop-start lines, you may want to configure the FXO module for ground-start operation instead by

moving the jumpers to positions 1 and 2.

For proper operation, you must configure both jumpers identically. In most cases, the jumper setting

should have little or no effect on operation.

Note This jumper setting does not apply to VIC-2FXO-EU.

Connecting the 2-Port FXO Module

Use a standard RJ-11 modular telephone cable to connect the 2-port FXO module to the PSTN or PBX

through a telephone jack. To connect the 2-port FXO module, perform these steps:

Step 1 Power off the AGM.

Step 2 Connect one end of the cable to one of the RJ-11 ports of the module, as shown in Figure 2-13.

Step 3 Connect the other end of the cable to the RJ-11 wall jack, as shown in Figure 2-13.
