14 AXB-DTMF+ DTMF+ Interface
Fine Tuning Send_Commands
The following table lists the commands that fine tune AXB-DTMF+ signal timing. Most likely, you
will not have to change Fine Tuning parameters.The commands are listed alphabetically by
operation and include syntax, syntax descriptions, usage examples, time increments, and reset
default values.
Timing System Send_Commands (Cont.)
Command Description
TONE TIME-XXX Set length of each generated tone and time between tones in the Dial
Send_Command (refer to 'DIAL-X-XXX-XXXX')
• Time increment = 1 ms
• Default at reset = 100 ms
Example:
SEND_COMMAND DTMF, 'TONE TIME-100'
Sets tone time length to .11 second (110 ms).
Fine Tuning Send_Commands
Command Description
CPGAIN-OFF When off does not add gain (in addition to IGAIN) to dial tone call progress sig-
nal.
Default at reset = YES
Example:
SEND_COMMAND DTMF, 'CPGAIN-OFF'
Sets gain into call progress detector chip as default.
CPGAIN-ON When on adds gain (in addition to IGAIN) to dial tone call progress signal.
Default at reset = NO
Example:
SEND_COMMAND DTMF, 'CPGAIN-ON'
Sets gain into call progress detector chip as default.
IGAIN-OFF Controls gain of "internal signals" on the AXB-DTMF+. The internal signals are
call progress tones such as incoming DTMF, receiver off-hook, and called num-
ber is busy. Setting gain to "off" causes it to return to default level.
Default at reset = YES
Example:
SEND_COMMAND DTMF, 'IGAIN-OFF'
Sets internal gain on AXB-DTMF+ to default.
IGAIN-ON Controls gain of "internal signals" on AXB-DTMF+. The internal signals are call
progress tones such as incoming DTMF, receiver off-hook, and called number
is busy. Setting gain to "on" increases gain above default level. This may be
helpful if signals are not being detected due to attenuation over the phone line.
Default at reset = NO
Example:
SEND_COMMAND DTMF, 'IGAIN-ON'
Sets internal gain on the AXB-DTMF+ to high.
