Like many FTTC lines back in august 2013 i started off with full speed no FEC, IMP or interleaving and it gentilly slowed over time overing around 72-76 mbps and for interleaving and the dreaded FEC/INP. Not helped by a impulse noise coming from next door on the same telephone pole creating noise that disappears at night and when they are all out in the day. It's to be expected I guess.
Well Neighbour and good friends second door away on the same telephone pole got FTTC today.
I know many people around here talk about their lines getting smashed but... Result is my downstream down by 17ish Mbps upstream down by 500Kbps
And my modem struggled to hold on to my old speed 728000 kbps for dear life at times with an overall 0.4db SNR margin, errors and all.
Unfortunately later on today I was putting in my nice new unlocked ECI /r modem to help with the interleaving and maybe help get that reduced. It's in now so no more graphing for now.
, The graphs capturing the SNR drop and speed drop are below, pretty dramatic for a final day capturing stats with DSLstats!!!
Surely is a case where vectoring could help big time, it's here, considering the cause of the speed drop to the very 10 minutes my neighbours modem came to life mine would struggle to hold on and settle about 17mbps slower. It's not like i was nasty or anything. I helped him get all his stuff connected up to his HH5 wireless, fitted a nice openreach VDSL filter to his master socket because BT don't supply them on self installs.
Such is life
