Call-Answered Supervision Pulse Option, Press

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.
