One-Way Span Test (#1214)
This test is destructive.
For documentation purposes, the term DS1 applies to the following:
DS1 Interface circuit packs
DS1 Interface media modules
UDS1 circuit packs.
One-Way Span Test (#1214)
FAIL The far CSU Loopback test was not set up properly. The DS1 Interface
circuit pack could not put the far-end CSU into loopback mode.
The far CSU Loopback test was not set up properly. The framed 3-in-24
test pattern, generated by the DS1 Interface circuit pack and looped back
through the far-end CSU, could not be detected by the DS1 circuit pack.
1. Enter test ds1-loop location
far-csu-loopback-test-begin
2. If the Far CSU Loopback test continues to fail with this error code,
the problem could be with the DS1 board, the far-end CSU
equipment, or somewhere in between. Run test ds1-loop
location cpe-loopback-jack-test-begin to see if the CPE
Loopback Jack test that is closer to the DS1 board is successful.
If a CPE loopback jack device is not being used, run test
ds1-loop location ds1/csu-loopback-tests to see if the
closer loopback tests succeed. If the closer loopback test fails, follow
the maintenance strategy associated with that loopback
PASS The Far CSU Loopback test has successfully began executing. The test
runs until test ds1-loop location end-loopback/span-test is
entered.
1. Enter release board location to release the trunks and ports.
