I've been having issues with general stability, frequent re-syncs and a drop in upstream rate over the past month, essentially, since all that rain we had begun. The previous fault I had was a 'contact fault' which the OR engineer appeared to have fixed but the current issue symptons are very similar. E.g. drop in upstream sync, missing upstream tones and frequent re-syncs, what is different is the upstream SNRM has a 0.5dB spike every 4 or 5 samples using DSLstats.
I contacted my ISP, IDNET, on Friday and as per, they didn't respond. I chased them on Saturday and have only just got a response this morning and they're stating that diagnostics report a possible internal wiring/ equipment fault. I don't have any internal wiring, not even a land line phone plugged in. The drop wire comes down the front of the house and straight into an NTE5 with NTE5C SSFP. The gateway (Billion 8800AXL) is then plugged into this via a bespoke 1m length of CW1308.
I have another gateway I can try, which I will do tonight, straight into the diagnostic socket of the master socket.
I'm intrigued to understand how the diagnostics can determine it's an internal wiring fault?!
Any thoughts would be appreciated.
