    No, your ISP is irrelevant if you use BT for your telephone service.
    True. Mea culpa, but you're nitpicking :bigsmile:

    It's not nitpicking, it's fundamental to understanding how this stuff works. What you wrote was quite misleading and would likely cause a repeat of some other misunderstandings further up this thread.

    This, presumably quite old, Openreach “ONT Factsheet” linked from https://www.premierenergy.co.uk/library/telecomms/openreach-ont-factsheet/ says “Connect a phone or fax machine to the TEL1 port of the ONT”.

    Found as bycatch in a search for what codec the Openreach ONTs use for the telephone port. I'm guessing G.711Mu [¹], probably with G.711.0 lossless compression but on very flimsy grounds.

    All internet connections now are fibre right to the house.

    That is utter tosh. They might want to, but If I wanted a new line, it would be copper not fibre. They are suggesting 90% of properties will have the ability to be connected directly to Fibre by 2025 (2020 figure). Any that do not have fibre 'passing' will not be connected by fibre. >



    I'm only reporting what the Openreach engineer said when he called a week ago to install a new line at our house, and my own observations.
    It is an isolated house, about 1/4 mile from a recently-installed passing fibre line. We previously had a copper landline for phone only, and local wi-fi for internet from a small relay mast about 2 miles away across the valley. This is vulnerable to poor weather, wind, rain, and branches getting in the way of the beam, and to the batteries at the mast seemingly endlessly needing replacement or recharging. Hence our recent switch to Openreach.

    He ignored the landline, as it was down a buried armoured cable, not in a duct.
    Instead he ran a new fibre-optic cable down a new series of wooden poles down our lane, entering the house as described in my first post.
    It was most definitely not a copper cable. He demonstrated the special machine he used for joining the cable, and then went and shone a light down it from the other end to confirm that it showed the right colour at our end.
    He said all new internet connections were like this now - they did not install copper any more. If necessary they put in new poles in order to run new fibre optic cables. Obviously he was only speaking for this area, which is west Wales, so obviously not as remote as say the Scottish Highlands, where perhaps different practice is used.
    There was no connection charge.

    This would actually be a sensible policy for new connections by OpenReach - cheaper to temporarily put some kit in the box on the street to convert the non-fibre connection to the cabinet to a FTTP connection from cabinet to house than to replace a copper cable with fibre to the property when the cabinet gets a fibre connection.

    And that is they key - "passing fibre". Yes where there is fibre, they will fit it in preference to copper. Where there isn't, they can't/won't. However, perhaps they do at that point put in the fibre. Perhaps I should ask for a new line and see what happens :).

    Interesting that they are now stringing fibre from a pole. AIUI, that was one of the issues initially. I hate overhead connections, just something else to break.

    Posted By: Cliff PopeThere was no connection charge.
    No, it is called the Universal Service Obligation - the fee is fixed if a completely new connection but often waived.

    As a matter of interest, is this a private lane or a public/adopted road? Did they enquire about wayleave?

    I have a BT pole in my garden that they do not have a wayleave for - it was there when I bought the land. I'm waiting for them to try and replace it so I can tell them to just remove it!

    At some point in time, it was decided all new title deeds had to have a clause allowing the placement of telecoms equipment on your land without wayleave. My deeds are that old, they do not have that clause in them. When I asked about it, openreach agreed they did not have a wayleave and offered Ă‚ÂŁ100 for one. I declined as I wanted the pole removed and they wanted several K to do so. They can stick it in the pavement across the road.

    Ordinary public road.

    They seem to be very free with their poles and where they put them - we have 3 on our land, no wayleaves for any of them.

    In the past 37 years we have had 3 different routes for entirely separate landlines. The original route went cross-country - once from pole to pole, but by 1985 most of the stretches of wire had been broken by falling trees, and joined by lengths of cable that were just strung along the hedgerows, with junction boxes at the foot of the poles. When the line went bad I used to set out down the line armed with a screwdriver and a can of WD40 to remake the connections and evict all the insects.
    When we got dial-up internet they re-routed the line along a set of new poles from a different direction, but that blew down after a few years.
    The next connection had new poles from yet another direction, including a long length buried in a trench dug by the local farmer. I pointed out to the BT man that his proposed route took the line straight through one of our trees, but he said that didn't matter, and I had no power to object to the route - they could put poles wherever they liked.

    The recent engineer said they never ran wires deliberately through trees - the friction caused them to break , as he said was already happening to this one. So the new fibre optic cable goes down yet another route, with more new poles.

    One day perhaps they will come to recover all their old poles, wires, sockets, junction boxes etc. :)

    When we built I was offered a choice of phone circuit off of a pole, like my next door neighbour, or of me digging a ditch (which I had to do anyway for water, drains and electric :) and putting a duct in it with an armoured cable in it that they also supplied. Of course, I went for the ditch and am glad I did, although we sometimes lose services (mostly electric) because of all the other properties served by poles. I believe the theory is they can blow fibre along the duct if we ever require it.

    We don't have a pole in the garden, but we do have a supporting wire of one. I keep getting letters from some solicitors offering to buy a wayleave from me for Ă‚ÂŁ100. My understanding is that if I keep throwing the letters away, as I do, then eventually me or my heirs will be able to refuse them access at which point they'll either have to move it or take whatever action they have to to enforce their right to keep it on my land. I hope that the pain of that action will be sufficient to motivate them to move it elsewhere.

    I have a feeling that there is a time limit after which their right to site the pole, or indeed any unauthorised feature, building, right of way etc, becomes enshrined. Don't you have to object to whatever it is, not simply throw away the letters?
