Use the pause command to display a full screen at a time by entering D H P.
Clear Error
Reset the error counter to zero by entering the Clear Error (C E) command
set. The error counter provides a convenient way to determine if the T1
link is performing without errors since it can be cleared and examined at
any time.
Testing
The Test Carrier (T C) command set enables tests to be run on the Lineside
T1 card, the T1 link, or the CPE device. These three tests provide the
capability to isolate faulty conditions in any one of these three sources.
See
Table 109 "MMI Tests" (page 252)
for additional information on these
three test types.
After entering the T C command set, select which test to start. The prompt
appears, similar to the following:
Test 1:
Local Loopback Test
Test 2:
External Loopback Test
Test 3:
Network Loopback Test
(1,2,3 or S to cancel):
Tests can be performed once (for 1 through 98 minutes), or continuously
(selected by entering 99 minutes) until a "Stop Test" command is entered.
Tests continue for the duration specified even if a failure occurs, and
terminate at the end of the time period or when a "Stop Test" command is
issued. Only a "Stop Test" command stops a test with a duration selection
of 99. After entering the test number selection, a prompt similar to the
following appears:
Enter Duration of Test (1-98 Mins, 0 = Once, 99 = Forever)
Verify DS-30A Links are disabled.
Hit Q to quit or any Key to Continue
Before a test is run, verify that DS-30A links are disabled because the tests
interfere with calls currently in process.
