Display the current timer resolution in milliseconds for the signaling
protocol timers.
Each signaling protocol comes with a set of timers, one for each type of
message in the protocol. These timers determine when an expected
response to a message is overdue. They are set to the expected response
time when the message is sent and decrement towards zero. If they reach
zero before the response is received the system is notified that the
response is overdue.
All the timers in the Q93B and QSAAL protocol are based on a common
timer tick-length called the timer resolution. When the timer resolution is
changed, all of the signaling timers are affected.
The CoreBuilder 9000 ATM Enterprise Switch is shipped with a default
timer resolution of 500 msec (0.5 secs). To change the value of an
individual timer, change the timer resolution proportionally. For example,
if you want to lower the "no response" timer from 50 secs to 25 secs,
reduce the timer resolution from 500 msec to 250 msec. Then the "no
response" timer, together with all the other timers, are reduced by one
half. For more information, see "Timer Resolution" on page 363.
