Re: POS Issues

Investigating a little further... in one side I have only PSE:, the other
side only NSEs:

A)
PATH
  AIS = 0 RDI = 0 FEBE = 0 BIP(B3) = 0
  PLM = 0 UNEQ = 0 TIM = 0 TIU = 0
  LOP = 0 NEWPTR = 0 PSE = 84069 NSE = 0

B)
PATH
  AIS = 0 RDI = 0 FEBE = 0 BIP(B3) = 0
  PLM = 0 UNEQ = 0 TIM = 0 TIU = 0
  LOP = 0 NEWPTR = 0 PSE = 0 NSE = 52239

Does this give any indication on what side might be causing the problem?
