DS1 Facilities Connectivity Test (#790)
This test is destructive.
The DS1 facilities connectivity test will check the correct connectivity of the DS1
facilities at opposite ends of the DS1 CONV Complex. Every part of this test is
executed under firmware control and the result is sent back to the maintenance
software.
FAIL Far-end lightwave transceiver loopback failed. A problem exists between the
DS1 CONV A and the lightwave transceiver connected to the DS1 CONV B
(see diagram above).
1. If there are facilities that are not digital data compatible, then busyout
those facilities via the busyout ds1-facility command.
2. If the test is executed as a part of an error analysis, then return back to the
related section.
3. Enter display errors and follow the associated repair procedures for any
on-board DS1 CONV-BD errors on this DS1 CONV circuit pack and the
DS1 CONV circuit pack at the other end of the DS1 CONV Complex. Enter
display errors and follow the associated repair procedures for any
DS1-FAC errors on the DS1 facilities.
4. Check the DS1 Converter Measurements Report to see if there are
facilities with excessive errors, execute command list measurements
ds1-facility summary. If there are facilities with excessive errors, execute
Far-end Internal Loopback test #797 on those facilities, and follow repair
procedures described for the test.
5. If the test still fails, replace the lightwave transceiver device that is
connected to the DS1 CONV circuit pack at the other end of the DS1
CONV Complex.
6. If the test still fails, replace the DS1 CONV circuit pack at the other end of
the DS1 CONV Complex.
7. If the test still fails, replace this DS1 CONV circuit pack.
PASS Transmission through the path of the loopback is successful.
0NO
BOARD
The system software found no board.
1. Reset the board.
2. Remotely retry the command.
