N392 and N393
These parameters define the error threshold for the UNI formed by
the DSU IQ network port and the frame relay switch. If the error
threshold is met, the signaling state status is changed to down,
which indicates a service-affecting condition. This condition is
cleared once N393 consecutive error-free events are received. N392
defines the number of errors required in a given event window,
while N393 defines the number of polling events in each window.
For example:
If N392=3 and N393= 4, then if three errors occur within any four
events the interface is determined inactive.
The status of the connection can be viewed in the S
TATISTICS
menu
under N

. The status will return to
active again once the threshold is no longer exceeded.
Management DLCI 1 and 2 (DLCI 1 and 2)
Enter the management data link connection identifiers (DLCIs).
These DLCIs are used to carry management traffic to and from the
network.
Management DLCI 1 and 2 Mode (DLCI 1 and 2 MODE)
Set to
D
EDICATED
if the management DLCI is used only to manage
the DSU IQ (and not used to carry customer traffic). If set to
D
EDICATED
, the router is not notified of that DLCI. Set to
S
HARED
if
the management DLCI is used for carrying customer traffic and
management data.
The network service provider should recommend the values entered into
the
T391 , N391 , N392 , and N393 fields.
