8.3 Configure Timers Request
This message is used to configure the timer values for all of the ISUP protocol
timers. It is an optional message and need not be issued if the internal
default timer values are acceptable. The message may be issued at any time
after the initial per-module configuration message has been sent to the ISUP
module. Timer values will take effect the next time the timer is started.
The timer resolution for all protocol timers is either in units of
num_tscan
system ticks or (in the case of T29 and T30) individual system ticks. Usually
the system tick is set to 100ms and
num_tscan (in the per-module
configuration message) is set to 10 giving timer units of 1 second and 100ms
respectively.
The maximum timer value is 512 seconds.
The ID field is used to select the timer table to be configured. Up to four
timer tables can be supported.
Note The signaling point timers always use table 0.
