rain last night, sync dropped, but it got me thinking. I’ve looked over all the previous sync losses or SNRM drops due to rain and it struck me that shorting to a capacitor (with different discharge rates) would look like that, and explain why the effect stops later even if the rain continues. I don’t suppose there is a capacitor or similar in the circuit?
The QLN also showed a significant positive jump during the resync. It would look good if the previous hadn't been seen
.
Edit: semi rhetorical question, what would it look like if rain allowed another conductor to become part of the circuit temporarily? An open or a bridged tap... or the above. Further edit: I'm at a loss, the only things I learned was that the QLN was about 5-10 db higher than normal at that point in the negotiation process and that the SNRM was at 5.9 at the point of Synch although this had increased to 7.9 within a minute. I was hoping the HLog would show something like a tap, but it doesn't
. Given the whole thing lasted 3-4 minutes (and the rain kept going) I not sure how the fault can be tracked back - quite often the SNRM drops by 2 or so and stays that way for a few hours, but it still seems a small window to fault find. I'm thinking of following Ixel's lead and provisioning a new line.
