Timers and Counters
3
Use this procedure to set timer and counter thresholds.
!
CAUTION:
The factory settings for these thresholds are standard and rarely need to be
changed. If you are not sure of the correct timer and threshold settings for
your PRI lines and trunks, check with your Lucent Technologies
representative before you make a change. Incorrect settings can cause
your PRI lines and trunks to malfunction.
If the network does not respond before the programmed time or count, the system
takes the appropriate corrective action.
The timers and counters are listed below.
■
T200 Timer. Times the delay in the link layer acknowledgment of a
message sent from the system to the network over a D-channel.
■
T203 Timer. Times the interval between each exchange of messages
between the system and the network on the D-channel.
■
N200 Counter. Counts the number of times the system has transmitted a
message on a D-channel because no link layer acknowledgment is
received from the network.
■
N201 Counter. Counts the maximum number of layer three octets the
system can send or receive in a single D-channel message.
