Electra Elite IPK II
10-09-01 DTMF and Dial Tone Circuit Setup
If dial tone detection is enabled, be sure to allocate at least one circuit for dial tone detection
[ICM/Trunk (0) or Trunk (2)].
14-02-05 Analog Trunk Data Setup - Dial Tone Detection for Directly Accessed Trunks
Enable(1) or disable (0) dial tone detection for manually dialed trunk calls. This option only
pertains to calls placed using line keys or Direct Trunk Access.
14-02-11 Analog Trunk Data Setup - Next Trunk in Rotary if No Dial Tone
If enabled, the system will skip over a trunk if dial tone is not detected. This option pertains to
calls placed using Call Appearance (CAP) Keys, Speed Dial, ARS, Last Number Redial or Save
Number Dialed. It does not pertain to line key or Direct Trunk Access calls.
21-01-05 System Options for Outgoing Calls - Dial Tone Detection Timer
If dial tone detection is enabled, the system will wait this interval for the Telco to return dial tone.
When this interval expires, the system assumes dial tone is not present. To disable this timer
(and have the system wait continuously), enter 0.
21-01-06 System Options for Outgoing Calls - Dial Pause at First Digit
If Dial Tone Detection is disabled, the system will wait based on this timer before sending dialed
digits. If using Dial Tone Detection, this timer should be set longer than the timer set in 21-01-
05, otherwise, if this timer is set shorter than 21-01-05, then Dial Tone Detection is satisfied and
21-01-05 is disregarded (not used).
Operation
Dial Tone Detection is automatic if enabled in programming.
