107 #
Max frequency value
of busy (reorder)
tone, FH
The system detects the frequency of the tone to be
recognized on the basis of between a maximum FH (set with
this parameter) and a minimum FL (set with the next
parameter). Being a limit it is necessary to extend it
subtracting 4 to the calculated value.
To calculate the value for a 425 Hz frequency follow the next
instruction:
•
(value) = (8000 / frequency FH ) – 4
•
(value) = (8000 / 425) – 4 = 18,82 – 4 = 14,82
•
so the right value is about 15
Range: max 2 digits, value 1-99
15
108 #
Min frequency value
of busy (reorder)
tone, FL
Like above. Being a limit it is necessary to extend it adding 6
to the value calculated. To calculate the value for a 425 Hz
frequency follow the next instruction:
•
(value) = (8000 / frequency FL ) + 6
•
(value) = (8000 / 425) + 6 = 18,82 + 6 = 24,82
•
so the right value is about 25
Range: max 2 digits, values 1-99
25

Sensitivity
comparator busy
(reorder) tone
detection
Value of “8” is the maximum sensibility. Value of “15” is the
minimum sensibility. If the busy tone is very low of level it is
necessary to keep the value of this parameter near the value
“8”, instead for high level busy tone is possibile to put an high
value to improve busy tone recognition in the presence of
voice and background noise.
Range: max 2 digits, values 08-15
8
160 #
Enabled recognition
of a continuous dial
tone
This parameter set AA-514 to recognize a line tone that lasts
more than 3 seconds, a continuous tone used in some PBX
to indicate busy or reorder state.
0 = function disabled
1 = function enabled
Range: max 1 digit, value 0-1
0
161 #
Enabled silence
recognition
This parameter set AA-514 to recognize a silence in line and
to close the communication. The length of silence to detect is
set in parameter 162
0 = function disabled
1 = function enabled
Range: max 1 digit, value 0-1
0
162 #
Silence time to be
recognized during
communication
Defines the minimum time for which the condition of silence
causes the call closing. In seconds.
Range : max 2 digit, 5-99
8
130 #
Waiting time for
dialing start
Defines the time (in milliseconds) that the system waits after
line engaging and before the selection.
Range : max 4 digit, values 0-9999
1000
132 #
DTMF duration
Duration of the emission of the DTMF tone (in milliseconds.)
Range : max 3 digit, values 0-999
100
133 #
DTMF pause
duration
Pause length of DTMF (in milliseconds).
Range : max 3 digit, values 0-999
100
167 #
Pulse dialing
Number pulse dialing with 60/40 milliseconds.
0 = function disabled, DTMF dialing
1 = function enabled, pulse dialing
Range: max 1 digit, values 0-1
0
170 #
Sleep Mode
Reserved parameter, don’t use.
0 = Sleep mode disabled
1 = Sleep mode enabled
Range: max 1 character, values 0-1
1
Keep
enabled
143 #
Enabling Camera
0 = Standard Operation
1 = Operation subject to the presence of the number dialed
by the caller in the table defined by the parameters 241-240
Range: max 1 character values 0-1
0
171 #
Camera operating
modes
Indicates how AA-514 manages the camera. It can be always
off, always on, or activated only during the conversation with
the visitor as a result of a call (both incoming and outgoing).
0 = Camera always disabled
1 = Camera always enabled
2 = Camera enabled only during call
Range: max 1 digit, values 0-2
