FTTC DLM

[Steve]

Sensitive beast!  I changed the LAN1 ethernet cable -thats all but it does seem to coincide exactly with the rise in ping, I don't see why I need to power the modem down prior to changing this but I guess would it be better next time to power down the router at least. It's partially recovered to the previous level this morning which is encouraging. Anyone seen similar on changing cables? I know it's not a dramatic change i.e.  at most an initial 4 msec rise in ping and now down to a 2 msec rise from previous.

My assumption is that this is a change in interleave depth but they are quite small changes.

I had one doubling (latency from 8-16) after about 2-3 weeks due I'm sure to the (totally expected on my line) introduction of interleaving.

No changes when I've messed about with the router (even "hot" changes of cabling) and even not when foolish me caused 35 resyncs last month whilst I was messing about. Not-caused-by-me-resyncs over my four months on FTTC, I can number on the total of my thumbs.

That's not interleaving Steve. It's just "one of those things" that I see on my connection from time to time. Either a temporary change in routing or a router/switch somewhere on the network is struggling a little.

I thought it was a very subtle change certainly nothing like what I've seen before, as you say interleave is usually fairly dramatic in it's effect on ping. It's early days I may have to delve deeper sometime.
