Avaya Media Gateway G700 用户手册

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 
test while the 3-in-24 pattern is active.

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 

 to troubleshoot.

The value of the 
Test: cpe-loopback-jack field is 
Pattern 3-in-24

The loopback jack test is active.

The value of the Synchronized field is N

Retry the test 5 times. 

The value of the Synchronized field 
remains N after 5 tries.

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.

The value of the Bit-error count field is 
non-zero

Repeat Step 1 several times. 

The value of the Synchronized field is Y

The DS1 circuit pack has synchronized to 
the looped 3-in-24 pattern and is counting 
bit errors in the pattern.
