High Line Attenuation?


[link to this post]
 
According to Kitz's website I'm 900m away from our local exchange, but when I enter the line attenuation into the speed checker it estimates me to be around 3km from the exchange. Does this mean my line has unusually high line attenuation, or am I just reading too much into it?

Connection Speed: 8888 kbps / 1274 kbps
Line Attenuation: 42.0 db (Down) / 22.6 db (Up)
Noise Margin: 6.1 db / 6.1 db

Only you can answer it by looking at where the BT infrastructure is located locally, and working out whether it is possible the phone line travels 3km to reach you.

If a phone works, and you are getting reasonable speeds for the attenuation, then unless you have aluminium cables the routing is probably having to do things like go around railway lines, rivers, historical routing etc

I'm 3.5 km from our Exchange and with ADSL2+ my attenuation was reported as 49dB. Was getting D/L speed of 1.5Mb/s with 6dB Margin.

Now on FTTC- goes like dried dog's s**t off a shovel!

The Line doesn't go in a straight line it might loop around the whole estate before it gets to you

It may follow the railway line for 0.5 miles, then cross the line and go back 0.5 miles

Your neighbour can have a line 1/2 the distance of yours.

It's nothing to worry about unless your having issues

or am I just reading too much into it?

Yes smile

Your house maybe 900m from the exchange as a crow flies but phone lines don't have wings.

As others have said lines can be like the long and winding road whether they are strung on poles or layed underground.

There's an area of parkland between me and the exchange which is prone to flooding/gets very boggy. I'm guessing it must go around it?

Pain in the ass that I can see the exchange from my window but have such a long route to it!

When BT laid the lines distance wasn't a concern. There was no concept of broadband so lines could be very long and sustain a phone service nicely. They generally did whatever was easiest, cheapest or most convenient at the time. In many regards this still occurs eg a new housing estates.

The wonders of BT.

Anyway your line looks fine.
