*61 Gain line 1 to line 2 000-030 dB Gain from line 1 to line 2.
NOT USED.
*62 Gain line 2 to line 1 000-030 dB gain from line 2 to line 1.
NOT USED
*63 PIN to make call 0,1 0 0 = no PIN
1 = PIN required to make call.
*64 PIN required to receive call in
manual answer mode
0,1 0 0 = * to answer call
1 = PIN to answer call
*65 ID required after PIN entry 0,1 0 0 = PIN can immediately be followed by number
or command
1 = user must wait after PIN for TACT ID
*66 Confirm manual number 0,1 0 0 = Dial after number entry
1 = Announce before dial
NOT IMPLEMENTED
*67 Line VOX Hang time
(VOX persistence)
0-1000 0100 PTT hold after line VOX de-activates and audio
delay is empty
*68 COS detect filter 0-1000 0100 ms how long a drop out is allowed in the COS
signal.
*69 Line VOX detect window
(VOX sensitivity) – see *13
also
0-15 12
20ms xx size of line VOX window. Increasing
the window size increases sensitivity.
*70 Line VOX count
(VOX attack time)
0-15 05 How many signal samples in line VOX Detect
Window for VOX activation. Number must be
less than VOX Detect Window. Decreasing the
count quickens attack time.
*71 Analogue radio transmit gain
(Line Radio Analog Tx Gain)
0-42 15 dB analogue Tx gain from phone to mobile radio
21 = 0dB
*72 Analogue radio receive gain
(Radio Line Analog Rx Gain)
0-42 18 dB analogue Rx gain from mobile radio to phone
21 = 0dB
*73 Digital gain radio to line
(Radio Line Digital Rx Gain)
0-99 46 dB digital Rx gain from radio
50 is 0dB
*74 Digital gain line to radio
(Line Radio Digital Tx Gain)
0-99 50 dB digital Tx gain to radio
50 is 0dB
*75 COS Sense 0,1 0 0 = COS active low
1 = COS active high
*76 Noise upper limit 0-255 100 qdB steps, sets upper limit for noise filters.
*77 COS Threshold 000
1-255
000
128
000 = digital (binary) input OR,
Voltage reference relative to 5V.
(128 = centre of COS swing 0 5V)
*78 No Rx (COS) from radio
disconnect timer
1-255 060 s. How soon radio must transmit to line for
connection to line to remain established.
*79 Radio VOX detect window
(Radio VOX Sensitivity)
0-15 12
20ms xx size of radio VOX window. Increasing
the window size increases sensitivity.
*80 Radio VOX count
(Radio VOX Attack Time)
0-15 03 How many signal samples in radio VOX Detect
Window for VOX detection.
Must be less than VOX Detect Window.
Decreasing the count quickens attack time.
*81 Radio Absolute signal level
detect (Radio VOX minimum
activate level)
0-255 050 qdB. Minimum detect threshold for Radio. Bigger
is less sensitive
*82 RS232 Modem COM Port
Functionality
0,1 0 0 = RS232 COM port operation for modem
1 = Alarm Input operation with AI-4775
*83 Permanent Line Connection
b/w two TACT units
0,1,2 0 0 = No permanent line connection
1 = MASTER permanent connection
2 = SLAVE permanent connection
*84 User Mode 0,1 1 0 = TA-4800 method of dialing phone numbers
1 = TA-7 method of dialing phone numbers
*85 VOX Override 0,1 0 0 = normal VOX operation
1 = DTMF 1 from phone forces PTT (Tx) and
DTMF 2 from phone releases PTT (Tx).
