statistics report
At the statistics:T1 prompt, enter the following commands:
(statistics:T1)>
report network carrier hour
The following is an example of a T1 line statistics report that will be displayed on
the PC monitor screen.
Network Carrier ONE HOUR REPORT
ESF Counter: 36855
Current Interval Time: 818
BPV
Current Count 0
24-Hour Count 4
Interval 1 0
Interval 2 0
Interval 3 0
Interval 4 0
NOTE: BPV= bipolar violationBES=bursty seconds
CRC= CRC errors
ES = error seconds
UAS = unavailable seconds LOFC = loss of frame count
Refer to TR-54016 or ANSI T1.403 for additional information.
If the count of bipolar violations (BPV) is high, verify that the T1 line coding format
is set correctly. If the line is set to bipolar 8 zero substitution (B8ZS) line coding
when it should be set to alternate mark inversion (AMI), this would cause bipolar
violations.
If you suspect a problem with the T1 line, enter the same report command
several times in succession. If the Current Count field for any condition
increments rapidly, a problem with the physical connection is indicated. If the
Current Count field increments gradually, verify whether the error rates fall within
the carrier's guaranteed Quality of Service. If they do not, contact the carrier.
