Display History
Entering the Display History (D H) command will display
performance counters for each hour of the past 24 in reverse chronological
order, beginning with the last full hour. A screen similar to Figure 47 will
appear.
The Pause command works the same for Display History as it does for the
other display commands. Simply enter D H P to see a report on the
performance counters, one screen at a time.

As with all Display commands, the Pause command can be used to
display a full screen of the history report at a time, by entering D H P.
Clear Error
You can reset the error counter to zero by entering the Clear Error (C E)
command. The error counter provides a convenient way to determine if the
E1 link is performing without errors since it can be cleared and examined at
any time.
The Test Carrier (T) command allows you to run tests on the LEI,
the E1 link, or the CPE device. The three tests are designed to provide you
with the capability to isolate faulty conditions to any one of these three
sources. See Table 47 on page 188 for additional information on these three
test types. After entering the T command, you will be prompted to enter
which of these three tests you wish to initiate. The prompt will appear similar
to Figure 48:
