ABOUT THE CALLMASTER
The CALLMASTER VI is a miniature, digital-voice terminal. It works in
conjunction with the DEFINITY
(ECS) Release 6.1 and your application software.
The DEFINITY ECS uses the CALLMASTER VI voice terminal to
download selected DEFINITY ECS configuration data to the
application software. The PC that is running the application software
controls the voice terminal through an EIA/TIA-574 serial port
interface, and full functionality is accessible only from that PC.
Power for the CALLMASTER VI voice terminal, including the headset,
comes from the DEFINITY ECS through the 2-wire DCP line. This
power allows the voice terminal to operate even when local power to
the PC fails.
The following sections explain the features of the CALLMASTER VI,
including the headset jacks, handset, buttons, and announcements
recorder.
Headset Jacks
Headset input jacks are located on both sides of the base of the
CALLMASTER VI voice terminal, as shown in Figure 1. You can plug
headsets into both sides at the same time.
