I have (5) CS1000M MG, (2) Release 7.5, (2) Release 5.0 and (1) Release 5.5. They are all network together via Fiber. I continue to get TRK165 at all (5) sites only on the spans to each of the (5) sites. This also creating REPT overflow thresholds in Load 60 for each and every Loop/Channel. Does anybody know what is creating these TRK165 codes and how to get rid of them?
