Verify that the controllers are up and no alarms or errors are detected. Error counters are recorded over
a 24-hour period in 15-minute intervals. In the display output, focus on the data in the current interval.

Snip
After each controller is correctly set up, clear the counters and look for ongoing line violations and
errors. To do this, enter the
clear controller t1
number
command followed by the
show controller t1
command. In the display output, focus on the data in the current interval. Error counters stop increasing
when the controller is configured correctly.
Tech Tip
The
clear controller t1
number
command does not reset or bring down the controller.
The T1 stays up. Only the counters are cleared.
If the counters are increasing on a specific T1 controller, look closely at the error statistics. Refer to the
commands in Table 2-5.
Table 2-6 provides a list of T1 alarm conditions and descriptions from the reference point of the NAS.
Table 2-5 Different Options for the Show Controller T1 Command
Command Purpose

Provides brief output statistics for the current
interval and the last 24 hours.
