10 AXB-DTMF+ DTMF+ Interface
Timing System Send_Commands
The following table lists the commands, which establish normal signal timing.
The commands are listed alphabetically by operation and include syntax, syntax descriptions, usage
examples, time increments, and reset default values.
Operative System Send_Commands (Cont.)
Command Description
ON HOOK Place AXB-DTMF+ on hook.
Default at reset = YES
Example:
SEND_COMMAND DTMF, 'ON HOOK'
Places the AXB-DTMF+ on hook.
Changing default time values may inadvertently alter the operation of the AXB-
DTMF+. It is unnecessary to change most default values.
Timing System Send_Commands
Command Description
BLOCKRDET-XXX For telephone lines with distinctive ring feature.
Time increment = 10 ms
Example:
SEND_COMMAND DTMF, 'BLOCKRDET-185'
Sets the time to ignore "sub rings " at 1.85 seconds (1850 ms).
FLASH TIME-XXX Set time AXB-DTMF+ will go "on-hook" when Send_Command FLASH is
issued.
• Time increment = 10 ms
• Default at reset = 63
Example:
SEND_COMMAND DTMF, 'FLASH TIME-65'
Sets time AXB-DTMF+ will go "on-hook" when Send_Command FLASH is
issued for .65 seconds (650 ms).
INROFFMIN-XXX Minimum time required for an incoming ring to be in the off
state to reset ring count on AXB-DTMF+.
• Time increment = 100 ms
• Default at reset = 45
Example:
SEND_COMMAND DTMF, 'INROFFMIN-55'
Sets minimum off state time for an incoming ring to 5.5 seconds (5500 ms).
LOSSLCMAX-XXX The maximum time a loop current is off (used to detect other end hung up).
• Time increment = 10 ms
• Default at reset = 80
Example:
SEND_COMMAND DTMF, 'LOSSLCMAX-90'
Sets a .9 second (900 ms) maximum off time for a loop current.
