Test
Result
3 FAIL The CPE Loopback Jack 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 CPE loopback jack, could not be detected
properly by the DS1 circuit pack.
1. Enter test ds1-loop location
cpe-loopback-jack-test-begin
2. If the CPE Loopback test continues to fail, the problem could be with
the DS1 board, the CPE loopback jack equipment, or somewhere in
between. Run test ds1-loop location ds1/
csu-loopback-tests to see if the loopback tests closer to the
DS1 board are successful. If any of those loopback tests fail, follow
the maintenance strategy associated with those.
PASS The CPE Loopback Jack 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 or ports.

Far CSU Loopback Test (#1213)
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.
The Far CSU Loopback (R-LLB) test causes a loopback at the far-end CSU, and tests all
circuitry and facilities from the local DS1 board to the far-end CSU.
The test is destructive and can only be initiated by entering the command
test ds1-loop location far-csu-loopback-test-begin.
