Technical Manual
Call-Answered Supervision Pulse Option
The following key sequence is used to enable or disable the call-answered supervision pulse, select
its frequency, and program its duration:
Press:
#
*
18
*
<cas_pls_enable>
*
<cas_pls_freq>
*
<cas_pls_duration>
*
<cas_pls_level> #
The <cas_pls_enable> value is set to 0 to disable the pulse, 1 to enable the pulse. If the value is
neither 0 nor 1, it will be considered invalid. The <cas_pls_frequency> value is set to 0 for 12 kHz, 1
for 16 kHz. If the value is neither 0 nor 1, it will be considered invalid. The <cas_pls_duration> value
is programmed in 1 ms increments from 10 to 65535 (10 - 65,535 ms). If the value is not between
10 and 65535, inclusive, it will be considered invalid. The cas_pls_level can be programmed to any
of the values shown in the table below. If the cas_pls_level is not between 0 and 6, inclusive, it will
be considered invalid. The factory default is
0, 0, 100 and 3.
Line-Reversal Outgoing Option
The following key sequence is used to enable or disable line (tip/ring) reversal for outgoing calls:
Press:
#
*
22
*
<line_reversal_outgoing> #
The line-reversal outgoing value is set to 0 to disable line reversal, 1 to enable line reversal. If the
value is neither 0 nor 1, it is considered invalid. The factory default is
0
.
Line-Reversal Incoming Option
The following key sequence shall be used to enable or disable line (tip/ring) reversal for incoming
calls:
Press:
#
*
23
*
<line_reversal_incoming> #
The line-reversal incoming value is set to 0 to disable line reversal, 1 to enable line reversal. If the
value is neither 0 nor 1, it is considered invalid. The factory default is
0
.
A-Key
The following key sequence is used to enter the A-Key:
Press:
#
*
27
*
<A-Key> #
If the A-Key is less than 6 digits or more than 26 digits, it is considered invalid and the FWT will not
update or store this value; the currently stored value will remain.
On-Hook Call Alert Cadence Option
The following key sequence will be used to program the on-hook call alert ring cadence:
Press:
#
*
30
*
<on-time> * <off-time> #
Both the on-time and off-time durations are programmed in 100 ms increments from 1 to 255
(0.1 - 25.5 seconds). If the value is not between 1 and 255, inclusive, it will be considered invalid.
The factory default is
20 and 40,
respectively.
On-Hook Call Alert Frequency Option
The following key sequence will be used to program the on-hook call alert ring frequency:
Press:
#
*
32
*
<frequency> #
The frequency value is set to 0 for 20 Hz, 1 for 25 Hz, and 2 for 50 Hz. If the frequency value is
greater than 2, it will be considered invalid. The factory default is
0
.
Audio Input Impedance Option
The following key sequence is used to select the audio input impedance:
Press:
#
*
68
*
<audio Z> #
The audio Z value is set to 0 for 600 ohms, 1 for 900 ohms. If the value is neither 0 nor 1, it is
considered invalid. The factory default is
0.
