My exchange (so far only ADSLMax) now appears to have TalkTalk LLU on it. I would be probably considering a reseller option based on SMPF to safeguard flexibility for the future. What speed might I expect?
For the existing ADSLMax service (Titan/Obit Surfwise) the modem stats are
Down 5120 kbps, Line Att down 24.5 dB, Noise margin down14.5 dB
Up 448 kbps, Line Att up 10.5 dB, Noise margin up 21 dB.
It is overhead copper wire and the actual line distance from the exchange is 1.6km.
Speed testers currently report 4407 kbps Down, 357 kbps Up. It's been consistently like that for a couple of months now although it was achieving (according to the speed testers) 5500-6000 kbps over the summer.
