Radio Receiver Active Tally Indicator
When a two-way radio interface port is assigned to a talk selector, the
LED will flash once per second when that radio’s receiver is active.
This tally must be enabled from the configuration program.
Panel Connected Tally Indicator
This tally is used when a panel is connected to the frame by a
high-speed data line (such as an ISDN or T1 line) that might be
inactive periodically. The red LED of any talk selector associated with
that panel will flash once per second when the panel is on-line. This
tally must be enabled from the configuration program.
Audio Presence Tally Indicator
When a label is assigned to a listen selector, the LED will flash once
per second to indicate someone is talking on that channel. This tally
must be enabled from the configuration program.
Answer-Back Facility
The primary function of answer-back facility is to answer or call other
panels or interfaces not assigned to a panel’s selectors. Panels and
interfaces that are assigned to a panel’s selectors also can be
answered or called with the answer-back facility.
The following sections describe the use of the answer-back facility.
Answer-Back Window
The answer-back window is located above the “Answer Back” selector.
It displays a list of as many as five incoming calls. The first caller’s
label is closest to the “Answer Back” selector and is highlighted.
Subsequent calls are placed to the right of the first in the window. This
list is called the answer-back stack.
Answer-Back Selector
The “Answer Back” selector answers calls from panels and interfaces
that are both assigned and unassigned to the panel.
When a call arrives from a panel or interface:
• The calling panel’s label will be placed in the answer-back stack and
be highlighted in the answer-back window.
• The red LED will flash.
These two conditions will continue until the call is answered, or until
the answer-back time-out period lapses and the caller’s label is
automatically removed. To answer the call, push the “Answer Back”
selector. The LED will stay on steady, indicating an active talk path to
the caller. The talk path is active for as long as the selector is held.
Note: The “Answer Back” selector cannot be latched; it is a
momentary-only function.
Calls from panels or interfaces assigned to panel selectors will also be
indicated by their associated LEDs.
