How to Commission the Cisco AS5850 Universal Gateway
Tip To save the gateway configuration, save it to NVRAM.
Verify
To verify that your controller is up and running and no alarms have been reported:
• Enter the show controller command and specify the controller type, slot, and port numbers:
Gateway# show controller t1 1/7
T1 1/7 is up.
No alarms detected.
Framing is ESF, Line Code is B8ZS, Clock Source is Line Primary.
Version info of slot 2: HW: 2, Firmware: 14, NEAT PLD: 13, NR Bus PLD: 19
Data in current interval (476 seconds elapsed):
0 Line Code Violations, 0 Path Code Violations
0 Slip Secs, 0 Fr Loss Secs, 0 Line Err Secs, 0 Degraded Mins
0 Errored Secs, 0 Bursty Err Secs, 0 Severely Err Secs, 0 Unavail Secs
Total Data (last 24 hours)
0 Line Code Violations, 0 Path Code Violations,
0 Slip Secs, 0 Fr Loss Secs, 0 Line Err Secs, 0 Degraded Mins,
0 Errored Secs, 0 Bursty Err Secs, 0 Severely Err Secs, 0 Unavail Secs
• Note the following:
–
The controller must report being up.
–
No errors should be reported.
Tip If you are having trouble, do or note the following:
• First decide if the problem is because of the T1 or E1 line or with a specific channel group. If the
problem is with a single channel group, you have a potential interface problem. If the problem is
with the T1 or E1 line, or with all channel groups, you have a potential controller problem.
• To troubleshoot your E1 or T1 controllers, first check that the configuration is correct. The framing
type and line code should match to what the service provider has specified. Then check channel
group and PRI-group configurations, especially to verify that the time slots and speeds are what the
service provider has specified. At this point, the show controller t1 or show controller e1
commands should be used to check for T1 or E1 errors. Use the command several times to determine
if error counters are increasing, or if the line status is continually changing. If this is occurring, you
need to work with the service provider.
• Another common reason for failure is the dial-tdm-clock priority setting. The default setting is a
free-running clock that causes clock slip problems if not set properly.
Task 4. Configuring Channelized T3
Your CT3 card offers 28 individual T1 channels (bundled in the T3) for serial transmission of voice and
data. The CT3 link supports the maintenance data link channel in C-bit parity mode and also payload
and network loopbacks. The T1s multiplexed in the CT3 link support facilities data link (FDL) in
extended super frame (ESF) framing.
