low. In addition; this measurement was made on an open loop. Open loop is more exposed to
crosstalk/noise than a closed loop.
Source may be found this way:
1. Select a loop which has crosstalk and/or has problem with loop raise
2. Disable suspected source loops
3. Do #PL_Clear to set counters to zero
4. Wait 5 minutes
5. Check #PL_stat to see any increase in frame errors (if increase is high source might be a
loop not disabled)
6. Enable a loop
7. Wait 5 minutes
8. Check #PL_stat to see any increase in frame errors
Repeat for all loops.
5.5 Serial numbers for verification (Recommended)
