Vox-Detect Indication
As stated previously, the vox-detect status can only be indicated for a line if a programmable button has
been assigned to the line. With a button assigned to the line, the LED serves to indicate both the selected
line and the vox-detect status. The vox-detect is indicated two different ways.
Vox-Detect on an Unselected Line
When a particular line is not selected, the associated button LED is not lit. When activity is detected on
the line, the LED blinks on and off at a constant rate with equal on and off times. When the vox is no
longer detected, the LED extinguishes approximately two seconds later.
Vox-Detect on a Selected Line
When a particular line is selected, the button LED associated with the line is lit. When activity is
detected on the line, the LED blinks on and off at a constant rate, but will be on twice as long as off.
This provides a method for the operator to know the vox status and the line-selection status. When the
vox is no longer detected, the LED stops blinking approximately two seconds later.
Unselect Volume Adjustment
The unselect volume adjustment is, in effect, an attenuation of the summed unselect audio. This allows
the unselect audio to remain ‘in the background’ when both select and unselect audio are both present.
To adjust the unselect audio:
1.
Enter the Line Selection Menu by pressing
SELECT
while in normal operation.
2.
While in the Line Selection Menu, press
VOLUME
U
P
or
Down to adjust the unselect volume.
3.
To exit the Line Selection Menu, simply press select again.
Optional External Speaker Kit
N
OTE
:
This optional feature requires the XAC0120A External Speaker Kit.
The XAC0120A External Speaker Kit includes all the components necessary to provide external
monitoring of the unselect channels of an IPE2500A-MLS Multi-Line Desk Set.
Please refer to Pub. 43003-029 included with the kit for specific installation instructions.
Alert Tones
Alert tones are selectable via the programmable buttons. Using the programmable buttons on the desk set
three types of alert tones are available. Refer to the CARD Suite Programming Software Help file for
programming instructions.
A continuous 1004 Hz alert tone.
A pulsed 1500 Hz alert tone; 250 ms on/off.
A warble alert tone; 250 ms at 800 Hz, 250 ms at 1500 Hz.
The
ALERT
button on the IPE2500A allows you to select from two types of alert tones to be transmitted:
Pressing the
ALERT
button generates a continuous tone of 1004 Hz.
Pressing the
CTL
+
ALERT
buttons generates a pulsed alert tone on 1500 Hz, 250 ms on and 250 ms
off.
