Hello all - Ive got three lines into my house (no FTTC or cable), from three different ISPs - O2, TalkTalk, Sky.
They all have the same physical run to the exchange, and a line attenuation in the range 30-33dB. I have two DG834Vs and a7800N.
The O2 line sync's fastest (to be expected) (14Mbs stable, 16Mbs tolerable, 17+Mbps unstable), with the TalkTalk line slowest (9Mbps stable, 11Mbps tolerable - just). The Sky line is interesting - it never drops changes from 10.2Mbps.
Ive use various SNR tweaks to get the best I (think) I can get out of the lines.
Two questions -
1. By establishing a stable, faster-than-profiled sync speed, is the DSLAM tricked into thinking a better target SNR can be achieved over time?
2. Why wont the Sky line sync at anything other than 10.2Mbs (despite a tweaked SNR of anywhere between 3-12 dB) ?
TIA
