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
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.
Testing
The Test Carrier (T) command allows tests to be run on the LEI, the
E1 link, or the CPE device. The three tests are designed to provide the
capability to isolate faulty conditions in any of these three sources. See
Table 113 "MMI Tests" (page 305) for additional information on these
three test types. Enter the T command, and at the prompt, enter which of
these three tests is to be initiated. The prompt is similar to Figure 75 "Test
Carrier (T) screen" (page 304) .

Stop Test command
is issued. Only Stop Test stops a test with a duration selection of 99;
