Table 26: DS1 Troubleshooting (continued)
Condition
The value of the Bit-error count field
pegs at 75535 or increments by 100s or
1000s each time you repeat Step 1.
The value of the Bit-error count field
is 0
Once you are fairly certain that the test is reporting no errors (after at least 1 error-free
minute), confirm that the 3-in-24 pattern error detector is operating.
6. Type test ds1-loop XXXVS inject-single-bit-error
where XXX is the administered number of the G700 or G350 (for example, 002), and VS is
the slot number on the G700 or G350 of the Media Module (for example, V3).
7. Type list meas ds1 sum XXXVS to display the bit error count again.
8. Step through Table 27: DS1 Bit-error count troubleshooting
Table 27: DS1 Bit-error count troubleshooting
Condition
The value of the Bit-error count field is
greater than 1
The value of the Bit-error count field is
still greater than 1 after you replace the
ICSU.
The value of the Bit-error count field is 1
Solution
Suspect loose or corroded connections,
severe crosstalk, or impedance
imbalances between the two conductors
of the receive or transmit pair. Wiring may
need replacement.
There are no obvious wiring problems.
Verify this by repeating Step 1 at 1-minute
to
10-minute intervals until you are certain.
If the test reports no errors for 1 minute,
the error rate is less than 1 in 10
test reports no errors for 10 minutes, the
error rate is less than 1 in 10
on page 381 to troubleshoot.
Solution
Replace the ICSU, and retest.
Replace the DS1 circuit pack, and
retest.
The test passed.
