TATISTICS
You can access WAN L1P statistics by issuing the wan l1p stats display
<slot #> console command. These statistics are divided into the following groups of statistics:
PRI S/T (T1/E1) interface statistics, error statistics, and layer 1 general statistics. These groups are
defined below.
PRI S/T (T1/E1) I NTERFACE S TATISTICS
Layer 1 Up
The number of times layer 1 has reported itself up to the upper ISDN layers.
Layer 1 Down
The number of times layer 1 has reported itself down to the upper ISDN layers.
L1 Deactivates
The number of times the upper ISDN layers requested layer 1 to deactivate.
Loss of Frame (RED)
The number of times layer 1 has detected a qualified loss of frame condition; excluding AIS (alarm
indication signal).
Loss of Signal (RED)
The number of times layer 1 has detected an all zero signal (or complete lack of signal).
AIS (Blue)
The number of times layer 1 has detected a qualified unframed all ones signal.
RAI (Yellow)
