Re: Any hope for long fttc lines ?

You could have a second phone line installed and a second FTTC connection installed,
- ho ho ho! Many cabinets are already maxed out on connection capability with 1 per house.

Re ADSL2+/VDSL the graphs I have seen (for good local loop) put the meeting point at around 2400m so, yes, I go for a rubbish local loop.

What do you base that info on ? THE busiest cab round here, PCP40 off of Reading South, has been in use for over two years, and still isn't full.

Regarding cable distances, has anyone any idea of how accurate the BE site is?

http://windows.mouselike.org/be/?DoAction=BrasChecker

It gives my distance as 1,286 metres, which ties in very well with the likely road distance and local cabinet distance.

Typically 24 db Downstream Attenuation, comparing well with 23 db measured around 1988.

The cabinet is literally "just across the road", say 25 metres directly north-west; but I know that my connection goes north-eastwards to a small, pavement jointing box, about 60 metres away, before heading westwards for about 65 metres (although there may be further wandering!) to the cabinet.

The pavement jointing box came to light when I had my line checked for noise around 1990, dial-up use then, when the source of the noise was traced to the joints in that little box.

It gives me 1263 metres. I am 664 metres straight line distance from the exchange, and the cabinet is 170 metres away (measured by pacing the cable route, not straight line distance)... so either it takes the scenic route between the exchange and the cabinet, or the distance is a bit overestimated.

Is that "as the crow flies" or is it (likely) road distance?

I am fortunate in that over about 500 metres, there is no choice, the other half having only two likely choices, with little difference between them.

The 664 metres is as the crow flies. The distance to the cabinet is measured along the (mostly visible) cable route. From there, the road distance is not very different from the straight line distance: essentially, head due west for 200 metres, then north-west to the exchange. Both roads are straight, so I'd estimate road distance at about 700-800 metres from cabinet to exchange and 850-1000 metres for total phone line length if it goes that way. But BT may have used different roads so the 1263 metres could reflect that. There are a few choices where a pointless detour can be taken.

My parent's place is about 30m as the crow flies from the exchange and it gives a length of 1276m which it probabaly in the ball park. Being all overhead lines you quite easily work out where the line runs.

In their case it runs from the exchange to the PCP which is about 500m then doubles back on itself for about 400m, then up the road for about 300m or so to a pole on the opposite side of the road just beyond their house.

In reply to a post by MHC:
Even when/if profile 30 is rolled out it will not offer very much extra (if any) to those far away from the cabinet.
I doubt if profle 30 will be around for a very long time.

The specification by Openreach for ISP-supplied modems says they must be 17a and vectoring capable. No mention of 30.
