T391/Status Enquiry Rate - Interval in seconds between the LMI Status
Enquiries issued by the FrameSaver NP 110 to the Network (Frame Switch).
The ratio of N392 to N393 defines the rate of Bad/No LMI responses to Count of
events, beyond which the Network link is declared Out-of-Service. This ratio is
set by selecting the values (1 to 10) for each of these parameters, defined as
follows:
N392/Event Error Threshold - Number of Bad/No responses to LMI Status
Enquiries issued by FrameSaver NP 110.
N393/Event Count - Count of all monitored requests (to be used for the ratio).
N391/Full Status Frequency - The Frequency Number “n” will cause every
“n
th
” LMI Status Enquiry issued to be a Full LMI Status Enquiry.
PVC BECN/FECN Threshold - FrameSaver NP 110 maintains a count of
seconds during which a receive frame contained a BECN or FECN bit set. When
the number of seconds containing BECN or FECN bits (flags) for any PVC in the
most recent interval equals or exceeds this Threshold Setting, an alarm is
declared.
5. User (DCE) - Consists of the settings required for the various protocols. These
include T392, N392 and N393.
T392/Status Enquiry Timeout - Timeout interval in seconds while waiting for
an LMI Status Enquiry from the User equipment.
The ratio of N392 to N393 defines the rate of Bad/No LMI inquiries to Count of
events, beyond which the User link is declared Out-of-Service. This ratio is set
by selecting the values (1 to 10) for each of these parameters, defined as
follows:
N392/Event Error Threshold - Number of Bad/No inquiries for LMI Status
Enquiries issued by the User equipment.
N393/Event Count - Count of all monitored inquiries (to be used for the ratio).
Force Full Status Response - Enable causes the FrameSaver NP 110 to send
four consecutive Full LMI Enquiry Messages toward the Network upon detecting
a recovery of its T1 link (or ISDN link if so optioned and active). Upon receiving
a Full Response it forwards that to the DTE, regardless of that enquiry type. In
some cases this will speed recovery from a link outage. Disable causes the
FrameSaver NP 110 to follow normal conventions per the N391 parameter.
6. Link Err Threshold - Disable or set the threshold of Data Frame Error Seconds
which when reached or exceeded causes an alarm to be declared. Set
independently for Network and User sides.
Commands:
Help [?] - Advances to “Help” for Frame Manager Configuration screen.
Save [SA] - Saves parameters and returns to System View screen.
Cancel [X] - Returns to System View screen without saving changes.
Save the Frame Manager Configuration changes when they are all set correctly by en-
tering “SA” followed by ENTER. Also returns the user to the System View screen.
Proceed to SNMP Community Access Configuration, selecting [SC] by typing
“SC” followed by ENTER.
