Information in PRI diagnostics report
• Slips (controlled slips)
— Caused by timing problems
— Links with multiple telcos are highly susceptible to slips
• BPV (bi-polar violations)
— Equipment is set to AMI instead of B8ZS (or vice versa)
— Noise
— With slips could be caused by NEXT (near-end crosstalk)
