I need to run a telephone extension, am I correct in assuming I can use CAT 6 cable for this?
I need to run a telephone extension, am I correct in assuming I can use CAT 6 cable for this?
The customers take on it is that they don’t actually use a landline phone anymore, they have unused phone extensions in the flat that are disconnected and a cordless phone that was turned off at the electric socket, they also always take their mobile phone when they go out so as well as using them at home, so will have them when they are in the lift.
I do wonder if I have run a fifty metre long phone line which may not actually be used or particularly fit for purpose.
It is probably also why it’s the first full landline phone extension I have installed in seven years, hence the moment when I had to stop and think about what I needed to do.
I did actually try connecting directly to the BT socket, but it only has an internet connection.
The final solution using bits out of my stock of cables and connectors was a secondary phone socket on both ends of the CAT 6 cable then a BT plug to BT Plug patch lead into the back of the Sky WiFi router, so the lift has an emergency landline phone connection that won't work during a power outage.
These lifts are built within the UK, the Chinese simply build a mobile phone into the control panel of their lifts, which is a simple solution so long as someone puts a SIM card into the phone and arranges payment for it, as well as changing the language on the phone to English.
One lady got stuck in her lift after her tea trolley wedged under it and the mobile phone display was in Chinese.
Of course that assumes the power cut does not affect the base station the mobile connects to. - given the short range of mobile phones, after all the average transmitter power is only a fraction of a watt, you are likely to lose the mobile connection and mains and fibre pretty much all at the same time, certainly for an HV side fault or a rota power cut.

Battery backed up VOIP boxes are supposed to be available for people who rely on the land line phone. But customers may have to specifically ask for one.
Most people have a mobile phone these days and would use that if the land line goes down.
No 'even' about Hull - it has always been quite progressive, and was a keen independent actor, being as far as I know the only City in the UK to be connected to but not part of the GPO network from the early days, then later as Kingston Telecom, not part of BT.
Apart from having different coloured phone boxes, they were very early adopters of the dial telephones - no more 'number please' in Hull at a time when when the rest of the UK was still on switchboards. Not too surprised to see full fibre, even if the city is no longer riding the wave of fish money.
But in any case the plan has all the copper de-enegised in a couple of years. Not sure how that works for places with a phone but no mains power.
When fibre to the home was first mooted, the idea was there would be an internal battery able to make emergency calls for a few hours, but this has fallen by the wayside as the full bandwidth internet solution is just too current hungry.
And of course the mobile base stations have the same problem, and generally fall over ni a power cut, it not immediately then after an hour or so - legally they do hot have to be backed up.
Also I suspect that there will be a lot more moaning in future when builders cut the fibre than there is now when they slice a bit of twisted copper, as the effort to do a splice in the field is rather more involved.

The old telephone network still works when there is no mains power, and I am not sure this IP everything is a good idea. During a power cut to an largish area, there will be NO telephone communication as most of the infrastructure is not battery backed up if everything is electronic. Accident or fire will happen but no communications from the public? Sounds like a disaster waiting to happen. Now does everyone see why "proper" electricity supplies are vital?
Why not go the whole hog, and fit a Cat6 RJ45 outlet instead of a phone socket, so the phone can be connected with an adaptor like this
If connected downstream of the linebox/master socket you're probably better off with the (cheaper) vanilla 'extension' version - https://www.tlc-direct.co.uk/Products/GPBT4503.html - the 'master' (and PBX master) versions re-generate the bell signal and can result in 'bell tinkle' when dialling especially if someone still has an old rotary dial phone or push-button phone set to LD dialling. UK phone deliberately short out the bell wire during LD dialling to prevent this - and master adaptors defeat that.

Therefore the phone line I am intending install tomorrow will need to be reinstalled within three years , so I might as well use a cable that can be reused.

... and so it can be more easily repurposed in a couple of years' time
