Analog trunk timing values
The following table describes the different types of inbound analog trunk timers for loop start
and ground start signaling types.
Inbound analog trunk timers (loop start and ground start)
Display Name Description Default Value
(msec)
Ring detect
trigger
Milliseconds of ringing to be detected by the
microcontroller before being reported to the
system software
250
CO drop (in/out)
Milliseconds of missing loop current detected by
the microcontroller before a line drop event is
reported to the system software
400
Disconnect
Maximum wait for far-end disconnect after
near-end disconnect of incoming call before
treating the situation as an error
10000
Subsequent Ring
Maximum time between subsequent rings before
deciding that far-end has given up calling
8000
Offhook Delay
The delay between sending offhook and the
switch connection being made. If callers hear
noise when being connected to a call on this
trunk, adjust this timer for an offhook delay of
160ms. Some experimentation will reveal the
best setting. Loop start only.
10
Inter-Digit
Maximum wait for the next digit before routing
the call
15000
Hold off, flash
(in/out)
Milliseconds after a flash before line events are
actively detected
500
Call Validate
Maximum time between first and second ring 7000
Hold off, onhook
(in/out)
Milliseconds after an onhook before line events
are actively detected
1500
Hold off, offhook
(in/out)
Milliseconds after an offhook before line events
are actively detected
800
