Testing The Integrity Of Data Sent Over The Loop - Avaya G700 Installation Manual

Testing the integrity of data sent over the loop

Now perform the second part of the test, checking for data errors.
Note:
The loss of signal (LOS) alarm (demand test #138) is not processed during this
Note:
test while the 3-in-24 pattern is active.
To test the integrity of data sent over the loop
1. At the SAT, type clear meas ds1 loop XXXVS to zero out the bit-error counter.
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).
2. Type clear meas ds1 log XXXVS to zero out the performance measurement counter.
3. Type clear meas ds1 esf XXXVS to zero out the ESF error count.
4. Type list meas ds1 sum XXXVS to display the bit error count.
5. Step through

Condition
The value of the
Test: cpe-loopback-jack field is
Pattern 3-in-24
The value of the Synchronized field is N
The value of the Synchronized field
remains N after 5 tries.
The value of the Bit-error count field is
non-zero
The value of the Synchronized field is Y
Table 26: DS1 Troubleshooting to troubleshoot.
Solution
The loopback jack test is active.
Retry the test 5 times.
Excessive bit errors are likely. Check for
intermittent connections or broken wires
in an SPE receive or transmit pair, and
repair as necessary. Then repeat Step 1.
Repeat Step 1 several times.
The DS1 circuit pack has synchronized to
the looped 3-in-24 pattern and is counting
bit errors in the pattern.
