Loss of Frame Count (LOFC) – The number of Loss of Frame conditions.
Complete – Indicates whether or not the 15 minutes worth of far-end
statistics contain 900 seconds worth of statistics. Bad T1 network conditions
or a loopback test can prevent far-end statistics from reaching the T1 access
unit. If one or more seconds of far-end performance statistics are missing,
then this field displays No. Otherwise, Yes is displayed. This field appears on
the Sync Data Performance Statistics screen only.
Network Performance Statistics
For the network performance statistics, these metrics are kept for each 15-minute
interval over the past 24-hour period. A Telco set and a user set are kept for each
metric. The user set is a copy of the Telco set, but the user set can be cleared.
In addition to the metrics kept for the network interface, the value of the Status
Event Register is kept for each 15-minute interval (user count only). The system
records the occurrence of the following events in the Status column:
Yellow Alarm (Y)
Loss of Signal (L)
Excessive Error Rate (E)
Frame Synchronization Bit Error (F)
Line Code Violation (V)
None
NOTE:
Network performance statistics are only available for those interfaces using
ESF framing. Verify that the Line Framing Format field on the Network
Interface screen is set to ESF.
To help you in selecting trouble spots, a Worst Interval is displayed on Line 18.
The Worst Interval contains the largest number of seconds for either ES, UAS,
SES, BES, or CSS, or the greatest Loss of Frame Count (LOFC). If more than
one interval contains the same worst value, then the oldest interval is displayed.
Sync Data Performance Statistics
For the sync data performance statistics, these metrics are kept for each
15-minute interval over the past 8-hour period. Both near-end and far-end
statistics are kept.
To help you in selecting trouble spots, a Worst Interval is displayed on Line 18 for
both near-end and far-end values. The Worst Interval contains the largest number
of seconds for either ES, UAS, SES, BES, or the greatest LOFC. If more than
one interval contains the same worst value, then the oldest interval is displayed.
