Hangup Detection Parameters
The Hangup Detection parameters provide information on how a switch indicates that a
caller has hung up. This allows the Octel 50 system to release the port and wait for
another call. There are three ways switches indicate hangups: dial tone, hangup strings,
or a drop in loop current. When the Integrator is run, the Octel 50 system sets the
parameters required by the switch.
Hangup Detection Parameters - #165
Dial Tone
Detection Time
(DTONDET)
This parameter specifies the amount of time, in 10
millisecond units, the Octel 50 system must detect constant
dial tone to determine a caller has hung up before dropping
the line.
When/How to Use
This parameter is set when the Integrator utility is run for
switches that use dial tone to indicate a hangup.
Adjust this parameter only when instructed to by a technical
support representative.
Related Parameters/Features
You must set DTONDET at least 4 seconds higher than
DTONWAIT. For example, if you set DTONWAIT to 300,
DTONDET must be set to at least 700.
If Set Too High
A high setting causes excessive off hook time between
calls.
If Set Too Low
Setting this parameter to 0 disables it, and the Octel 50
system does not detect dial tones. The result is excessive
off hook time between calls.

Hangup Detection Parameters - #166
Hangup String
(HANGUPSTR)
This parameter defines the sequence of digits the switch
sends to indicate a hangup.
When/How to Use
This parameter is set when the Integrator utility is run for
switches that use hangup strings to signal disconnects.
If your switch is programmable, and you modify the hangup
string, be sure the string does not represent a sequence of
keypresses that a caller might use to navigate through Octel
50 system menus.
The minimum and maximum values for this parameter refer
to the length of the entry allowed, not an actual number.
Related Parameters/Features
If using a hangup string, the Hangup String Timeout
(HANGUPDLY) should be a value greater than 0.
