Vega’s C-2002
7.7.2 Incoming Select Call DTMF String Setup
The C-2002 has the capability of recognizing 3 different incoming DTMF strings on any line, monitored or not.
When this programmable string is decoded, the unit will Un-mute the line for a programmable period of time (see
Select Call Timer Duration Setup) to allow the remote user the opportunity to make a short transmission which the
console operator can monitor. After the programmable period of unselect time has expired, the Unselect LED (Red
led) for the line on which the DTMF string was decoded begins to flash and continues to flash until a PTT operation
is completed on that line. This blinking light serves as a reminder to the console operator that a call was received
and needs a response. Editing the incoming DTMF sequence is completed from the screen shown. The digits are
entered with the DTMF keypad and the programmable keys; use the “D” key as save/enter function.
