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

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

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).

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