Re: Noise on the line

My problem started after an engineer was interfering with the line as they had supposedly found battery voltage, but the engineer said he had modified the tie pair, which has caused all of these problems!

Without seeing a full set of stats hard to say anything, and even then probably an inconclusive answer.

ADSL Link Downstream Upstream
Connection Speed 2144 Kbps 448 Kbps
Line Attenuation 60.1 dB 31.5 dB
Noise Margin 9.2 dB 21.0 dB
This was before the engineer supposedly modified the tie pair, below are the current stats? As you can see both the noise margins are lower and the attenuation has increased.

ADSL Link Downstream Upstream
Connection Speed 1280 Kbps 448 Kbps
Line Attenuation 65.3 dB 31.5 dB
Noise Margin 9.1 dB 15.0 dB

Perhaps your modulation is now ADSL2+ ?

Oh well, I'll have to call a n other Openreach engineer in I suppose smile

Plusnet has offered me FTTC at a once only - never to be repeated price, but that still leaves 1 mile of copper/aluminium, and I really don't want another 18 month contract, all I want, what I really really want, is 3-4 Mbps down wink

Putting the better set of figures into MrSaffron's calculator indicates that much more than 2.7Mbit/s is unlikely.

What is your predicted FTTC speed?

No g.dmt adsl, I changed nothing my end it was after he did something with the tie pair has brought on some other fault I've tried different filters, routers, it's all the same,I personally think the fault is from the cab to the exchange somewhere maybe even in the exchange.

Up to 14Mbps, but I really don't want to go down the fibre route

Something has added around 0.5km of metal wire some where to the line.

The lower noise margin on upstream, probably reflecting the increased attenuation which you cannot see as the router only displays the usual maximum 31.5dB.
