Configure a Channelized T3 Interface Processor
IC-90
Cisco IOS Interface Configuration Guide
Use the show controllers t3 command to display MDL information (received strings). MDL
information is displayed only when framing is set to C-bit.
Enable Performance Report Monitoring
The CT3IP supports performance reports via the Facility Data Link (FDL) per ANSI T1.403. By
default, performance reports are disabled. To enable FDL performance reports, use the following
commands beginning in global configuration mode:
Note Performance reporting is available only on T1 channels configured for ESF framing.
To display the remote performance report information, use the following command in EXEC
command mode:
Enable BERT Test Pattern
To enable and disable generation of a bit error rate testing (BERT) test pattern for a specified interval
for a specific T1 channel, use the following commands beginning in global configuration mode:
The BERT test patterns from the CT3IP are framed test patterns (that is, the test patterns are inserted
into the payload of the framed T1 signal).
To view the BERT results, use the show controller t3 or show controller t3 brief EXEC command.
The BERT results include the following information:
• Type of test pattern selected
• Status of the test
• Interval selected
• Time remaining on the BERT test
Step Command Purpose
1 controller t3 slot/port-adapter/port Select the CT3IP and enter controller configuration
mode.
2 t1 channel fdl ansi Enable one-second transmission of the performance
report for a specific T1 channel (values are 1 to 28).
Command Purpose
show controller t3
[slot/port-adapter/port[:t1-channel]] remote
performance [brief | tabular]
Display the remote performance report information for
the T1 channel (values are 1 to 28).
Step Command Purpose
1 controller t3 slot/port-adapter/port Select the CT3IP and enter controller configuration
mode.
2 t1 channel bert pattern {0s | 1s | 2^15 |
2^20 | 2^23} interval minutes
Enable a BERT test pattern on a T1 channel (values are
1 to 28).
3 no t1 channel bert pattern {0s | 1s |
2^15 | 2^20 | 2^23} interval minutes
Disable a BERT test pattern on a T1 channel (values
are 1 to 28).
