When the remote unit detects the loopback Up command, it puts itself in line loopback and lights the front panel Test LED. The remote unit remains in loopback until it receives a loopback Down command or the remote unit’s test timeout value is exceeded. The Send Line Loopback tests both units. External equipment can be used to verify the link.
8. Testing Send and Monitor 511 The Send and Monitor 511 test causes the local and remote units to send a 511 test pattern to each other. The front panel Test LEDs of both units are on during the test. The duration and results of the test are displayed on the Network Test screen of the initiating unit. The card will send ones in the G.703 timeslots that are mapped to the DSL port in test. NOTE: The Send and Monitor 511 test is not a loopback test. Each unit independently sends and monitors a 511 pattern.
8. Testing Device Tests The Device Tests branch is only used to access the card-level test, the Lamp Test.
8. Testing Ending an Active Test Except for the Remote Send Line Loopback, a test initiated by the user can be ended by the user with the following methods: Test Timeout option – Enable the Test Timeout system option so the unit can automatically terminate tests, and set the Test Duration (min) option to specify the amount of time that tests can run before the unit terminates the test. The default is 10 minutes. Refer to Table A-7, System Options, in Appendix A, Configuration Options.
8. Testing Telco-Initiated Tests Hotwire 8777 Termination Units support Telco-initiated tests, as shown in the following table.
8. Testing Telco-Initiated Remote Line Loopback If Remote Telco Loopback is enabled, a Telco-Initiated Line Loopback loops received data at the remote unit and passes it back to the Telco through the local unit. The following figure shows the data flow for a remote Telco-initiated payload loopback.
