Testing the Module Ports

After you install the Module, test each port on the Module:

1.Connect a handset to one of the RJ-11 jacks on the Module.

2.Lift the handset and listen for a dial tone.

3.Verify that the LED above the jack remains green, while the LEDs for the other 7 ports turn red.

4.Repeat this procedure for the remaining Module ports.

Connecting Endpoint Devices

Connect an endpoint device to the Module’s RJ-11 jack labeled J1 (which corresponds to port 1). Connect the remaining endpoint devices to any of the other RJ-11 jacks. A remote host can communicate with one endpoint device at a time using either of the following methods.

In both cases, the connection is maintained until the host or meter ends it. When a host connects to an endpoint device, the LED above the port being called remains green. The LEDs for all other ports turn red to show that they are “locked out” until the host goes on-hook. You can also connect a phone to the OMEGA’s RJ-11 jack to originate and receive calls as you would normally.

The host can communicate with an endpoint device in two ways: using the Time Delay method or the Second Dial Tone method.

Time Delay Method (Automatic Connection)

With this method, the host computer calls OMEGA and waits for a connection. When connected, the host sends a DTMF digit that corresponds to a number from 1 to 8 on a touch-tone telephone or via a modem. This number corresponds to the port with which the host wants to communicate. For example, sending the DTMF digit 4 corresponds to port 4.

When OMEGA is configured for the time delay method, the host issues the following dial string:

ATDT<phone number>,,,<port number> <Enter>

In this string:

c<phone number> is the OMEGA phone number (and area code, if required).
