How shorthold mode works for OUTGOING connections

|
|
|
|
|
|
unitlen - specifies the time a charging unit lasts
|
|
idle_time - specifies the thime the line must be idle at the
|
|
end of the unit to be elected for hangup
|
|
earlyhup - is the beginning of a timing safety zone before the
|
|
next charging unit starts
|
|
|
|
The algorithm works as follows: lets assume the unitlen is 100
|
|
secons, idle_time is 40 seconds and earlyhup is 10 seconds.
|
|
The line then must be idle 50 seconds after the begin of the
|
|
current unit and it must then be quiet for 40 seconds. if it
|
|
has been quiet for this 40 seconds, the line is closed 10
|
|
seconds before the next charging unit starts. In case there was
|
|
any traffic within the idle_time, the line is not closed.
|
|
It does not matter whether there was any traffic between second
|
|
0 and second 50 or not.
|
|
|
|
|
|
How shorthold mode works for INCOMING connections

=================================================

it is just possible to specify a maximum idle time for incoming

|
connections, after this time of no activity on the line the line

is closed.
