Testing the Module Ports
After you install the Module, test each port on the Module:
1.Connect a handset to one of the
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
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
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
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).
