Configuring the Serial
Card
User (or Network) Error Threshold (N392) / User (or Network) ME Count
(N393) — These parameters are related. The User (or Network) ME (Monitored
Event) Count is the threshold period that you set to determine a service-affecting
condition. The unit monitors events—receipt of Status Enquiry messages or
expiration of polling timers (on the user or network side)—for the number of
seconds (3..10) that you specify. Within this specified User (or Network) ME Count
period, if an error occurs (on the user or network side) within the number of
seconds that you specify as the User (or Network) Error Threshold (3..10), the
system declares an error.
You must set the User (or Network) Error Threshold to a lower value than that of
the User (or Network) ME Count.
Network PV Timer (T392) — Network Polling Verification Timer. When the unit
is configured as the network side unit, the user side unit sends the Status Enquiry
request. The Network Polling Verification acts on the user initiated-request and
checks whether or not it has any new information to report, based on the
specified timer.
End-to-end LMI — Use this option to specify whether or not you want LMI
messages—specifically, messages regarding problems affecting VCs connected to
the Frame Relay port—to be reported from the ATM side. When you enable
End-to-end LMI, problems on the ATM side are reported back to the Frame Relay
port via LMI messages. In this way, the router to which the Frame Relay port is
connected can detect problems on the ATM side. When you disable End-to-end
LMI, LMI messages are sent only between the Frame Relay port and the router to
which it is connected.
Set Defaults — Use this option to reset the LMI parameters to their default
values, thereby restoring a known working LMI configuration.
The only type of configuration you can perform on the serial card is to put it in
service or out of service.
To set the administrative status of the serial card:
1 From the Configuration Management menu, shown earlier in Figure 59, select
[1] Manage Card to open the List Card menu, shown in Figure 60.
2 From the List Card menu, select [5] SIM to open the SIM Configuration Port/Card
Selection menu, shown in Figure 85.
3 Select [2] Card Configuration to open the SIM Card Configuration menu, shown in
Figure 89.
