DS1 Board Loopback Test (#1209)
User impact may range from noticing nothing to not being able to use the
port.
1. Check the results of the Local Loop Test (#13).
2. If that test fails, suspect the Digital Line circuit pack. Run test
board location on the Digital Line circuit pack. If the tests pass,
replace the terminal.
3. If component replacement does not change the results, then:
a. Run circuit pack tests to check the tone generator circuit and the
Tone Detector circuit using test board location.
b. Resolve any problems that are detected on the TONE-PT (Tone
Generator) or TTR-LEV (TTR Level).
PASS The test passed. All channels are transmitting properly.
1. To verify that this is not an intermittent problem, repeat this test up to
ten times.
2. If problems persist (noisy connections for voice, corrupted data
transfer for data), examine the station, connections, and wiring.

This test is destructive.
The DS1 BLB (Board Loopback) Test causes a loopback at the DS1 board edge and tests DS1
board internal circuitry.
This test is destructive and can only be initiated by entering the command
test ds1-loop location ds1/csu-loopback-test.
All trunks or ports on the DS1 Interface circuit pack must be busied out using busyout board
before running the BLB test.
When the BLB test is initiated, maintenance software sends a message to the DS1 Interface
circuit pack. The board sets up the BLB loopback, transmits a test pattern, and verifies that the
