Answering a call

Operation ~ Front Panel Control

✍

If Auto-Answer is turned

On under System settings,

 

the GT1524 answers the

call after the second complete ring. A ringing tone is provided to the Line and Speaker output if Ring Indication is turned on.

An incoming call rings on the telephone set connected to the GT1524 (and speaker, if one is connected to the GT1524) and causes the On LED to flash. There are four ways to answer an incoming call:

To answer a call

You can answer a call using any of the following methods:

•Press the On button on either the front panel or on the remote control. This will route the call through the GT1524.

•Pick up the telephone handset and talk to your party over the telephone. Press the front panel On button to connect the call to the GT1524.

•Use external control such as an AMX or Crestron touch panel or custom control device. See page 21 for information on using serial commands.

When

using the DIAL

port

command, the

GT1524

automatically

engages the hybrid. You do not need to press the On button.

Making a call

Call the party using your handset. After the other party has answered, route the call through the GT1524 by pressing the On button.

The On LED lights and the GT1524 takes control of the call, disabling the telephone set. You can now safely hang up the handset without disconnecting the call or access the DTMF dialer in the GT1524 via a remote control system.

Disconnecting a call

If the call is routed through the GT1524 (the On LED glows green), press the Off button on the front panel or send a command through the RS-232 port (TE 0). The Off LED glows red, and the On LED turns off.
