All the timers in the Q.2931 and Q.SAAL protocol are based on a
common timer tick-length called the timer resolution. When the timer
resolution is changed, all timers are affected.
The CoreBuilder 9000 ATM Enterprise Switch is shipped with a default
timer resolution of 500 msec (.5 secs). To change the value of an
individual timer, you need to change the timer resolution proportionally.
For more information, see "Update Protocol Timer Resolution" on
page 199.
