BT Plans Move To IP Telephony, Starting Next Year
pure_equanimity writes "The BBC have published an article saying that BT are planning to migrate from a PSTN to an IP network, a move to cost 3bn. They say that broadband will become ubiquitous, with customers having the ability to plug any device in to get access. They also say that current cheap broadband products will more than likely not be viable in five years time. They plan to start rolling out in 2006, and cover the vast majority of customers by 2009."
This was the last thing I expected from BT after their faffing about with getting DSL sorted out a few years back. This should be interesting...
Too bad I'm not a BT customer. I wonder what will become of all of the mini-telcos which currently hang off BT's network.
"They also say that current cheap broadband products will more than likely not be viable in five years time. They plan to start rolling out in 2006, and cover the vast majority of customers by 2009."
So they are gonna hook customers up right before the prices go up? I thought prices would go down as time marches on? What about all that "dark fiber"?
I'll admit I had to look this one up, if ya woulda said POTS, I would of known right off the bat.
Public Switched Telephone Network btw.

Good Luck with that BT. There are tons of people out there with old rotary phones still, utilizing pulse dialing. They're not going to get some old lady to change her pots phone for some fancy IP phone.
do people in britain (and other countries) suffer from the RIM syndrome? ie being on a remote integrated multiplexor? or even being pairgained? If its common over there, does that mean BT will be ugprading all their exchanges?

You can bet their charging scheme will change to p/minute to p/MB of data. That way they can cash in on all the "free" telephony.
"cheap broadband products will more than likely not be viable in five years time"
:-)
BT don't do any cheap broadband products, only expensive overpriced ones
Well, everyone will just register a .phone domain for themselves, so you can just call them by name.
God help you if you're John Smith!

Most likely they'll continue to use phone numbers. It's too much of an investment to try to change the number system, and on top of that, it'd be much harder for a traditional telephone to call an IP number.
Basically, they're turning the voice data into packets and then sending the packets across their network, improving the effeciency of their lines. There's been a lot of discussion about this lately actually. Either way, I wish the american phone companies would get on the ball...

Uncompressed telephone-qualtiy audio as PCM takes up 64 kbps (8 KB/s), just like an ISDN channel.
It will certainly not be as bad, load-wise, as installing high-speed Internet access.
Phone service to the UK is temporatily unavailable due to the Sasser.Q virus. Please try again later.

When Skype come out with their telephone kit that plugs straight into the new BT network will BT cut off people trying to use another handset? They might, but they wont get away with it.
This is going to be the biggest revolution in telephony the UK has ever seen. Whilst a Skype handset might not connect you to phones that are not on their network, if enough people use it, it could supplant the BT network and destroy their business.
I wonder how they are going to charge for the service, obviously line rental, which will be the minimum they will be able to collect from each user, but taking into consideration the ease with which people will be able to switch providers, their churn rate will be very high indeed.
Basically, they are going to spend 3 billion to put themselvs out of business. Great!

I imagine that the majority of phone call traffic will never leave BT's network, since the uptake of IP telephony in the rest of the world is still quite small.
Even if similar moves are made in other countries, I'm sure BT have some connections that could keep it local until it hits the remote exchange.
The backend is going to be IP based you fool. So we'll still have telephone numbers etc, but BT will route all of the call data via IP. So, basically, they'll reduce the already tiny operating costs even more, whilst attempting to bump up the cost of xDSL even further. They'll probably argue along the lines of "Mr X uses much more bandwidth now so we have to charge more". The excess bandwidth being Mr X's telephone calls, which he is already paying for.
This might help:
The public switched telephone network (PSTN) is the concatenation of the world's public circuit-switched telephone networks, in much the same way that the Internet is the concatenation of the world's public IP-based packet-switched networks. Originally a network of fixed-line analog telephone systems, the PSTN is now almost entirely digital, and now includes mobile as well as fixed telephones.
It fills me with dread to hear this news. I'm living in an area where BT have still not yet managed to install a DSL network. To hear that they've got more plans when they haven't even finished their old broadband roll out after god knows how many years seems plain stupid. It makes me angry.
Yes old chum. Try taking The Times for a few weeks, you'll soon understand what the Empire is about.
If I promise to be a good boy can I have some better karma?
Don't worry. The government will restore your conversation from their backups as soon as power is restored :/
This is a fairy tale dreamt up for investors, and you can expect within 2 years an announcement that it's all much harder than expected.
The UK phone network is not a simple beast, and not like any other phone network in the world. I suspect they're putting down the plan and hoping that they can start angling for some government "investment" to replace the absolute crud we have in place at the moment.
I would advise caution however, when BT announce anything at all. Remember this is the company who announced "universal" broadband 15 years ago and sat on the technology when it became available until they were effectively bullied into it.
BT is BT. Sure, officially they are British Telecommunications plc, but it's not like you'd bother looking up what AT&T stood for, when all you needed to know was "it's a big telco".
That mild voltage is supplied by the central office via huge banks of batteries supplying a 48V DC feed.
Since a lot of COs and switching centers already have this massive infrastructure for supplying DC power most (if not all) internetworking equipment can be obtained in DC power supply versions.
So yes, the equipment at the CO will stay up through a power outage because it'll still be powered by those 48V batteries, equipment at the customer end is a completely different thing... but unless it's a full FTTH solution there are options for getting power to the CPE, like power over ethernet (if they use an ethernet last mile), and iirc there are power distribution solutions for coax if they decide to go that route.
The technology for this just isn't ready. The internet wasn't designed for having all these low-latency desiring services tacked onto it, and not everyone has a 50ms ping. What worries me about this is that the brits don't seem to have a choice in the matter, and are being shepherded into this under the guise of "new technology, newer is better".
The sad truth is the individual pieces work ok, but put the ISP, the routers, the voip boxes together, and you've got one hell of a mess.
Even those who arrange and design shrubberies are under considerable economic stress at this period in history.
the majority of BT users rent their phones for an annual cost that is far greater than buying one.. check out the House of Lords report. So it should be easy for BT to send them a new one, because they already own the rented one.
They also say that current cheap broadband products will more than likely not be viable in five years time
BT have cheap broadband products? Yikes, they've kept that well hidden!
One of these would be extremely good for the UK and very forward thinking, the other would be investing money in a technology already straining to bursting point...
And on another note, how cool will it be to have links like <a href="phonecall:phone.mydomain.com">Phone Me!</a> on websites - how long until we have that I wonder?
Yes, and I *really, really* hope they have made provisions to switch to IPv6 or are doing everything on top of IPv6.
It would be a pain in the a** to update all the people's IP telephones from IPv4 to IPv6 (If it would be possible at all). And that would hamper the spread of IPv6 alot.
They are brave enough to switch to IP, hopefully they're also brave enough to switch to IPv6.
...they changed the trading name from British Telecom to 'BT' in 1991 and the corporate name to BT Group plc in 2000. You will find it hard to actually even find a reference to 'British Telecom' on bt.com.
I think a lot of people including the press are missing the point here. The main thing here is not VoIP or fibre it is that BT are going to be migrating all of their services onto ONE IP network off of there existing PSTN, ATM and IP networks.
Obviously while this will eventually have implications for end users (BT are talking of a broadband dialtone) the main benefits will be a big cost saving for BT and the ability to quickly deploy new services onto the network.
BT seem to be gearing up for something, or reacting to something. Its strange for them to have such a flurry of activity as they have had of late, normally they are quite the epitome of corporate dawdling on products and issues.
Seems that they are wanting to seriously get themselves some press time, and in my opinion are using some clever marketing to do so.
Look at the ammount of new services / announcements / products they are kicking out the door at the moment listed on El Reg.
In my opinion, this is nothing short of marketing genius. Anyone who cries out against the obvious censorship issues risks being labelled. It pushes this kind of activity under ground. so who does this really protect? the only real benefit i see from this is accidental visiting of sites, from bad links, spam or whatever. It certainly wont stop any actual people wishing to view child pornography from getting to it.
BT have made an unprecedented movement to block this content, thereby championing themselves with many different groups of society (churches, parents, police, etc etc) - but the same fanfare that has delighted these groups has warned any of the sickos that actually want to view this content that they cant use BT services to get their kicks. OK then, so they go elsewhere. No one would continue to use a service they know can not suit their needs, as underground or sick as those needs may be, they will simply move to another provider that doesnt block in this way.
Marketing genius - Champion yourselves with lots of the country, by actually bringing little to no benefit to them or anyone else.
Then sharp on the heels of this announcement, tell the people who you have just delighted that you are going to be saving them a lot of money soon by changing the infrastructure of your network etc and routing your calls using VOIP. Thinking of leaving BT? They seem to be keen to impress and promise lots, all within a week. something strange is going on, i just cant figure out what, heh.
Telecom Italia already carries 80% of its national backbone telephone calls on an IP based network infrastructure, and something like 40% of their international calls.
This is the back-end of the service, multiplexing together thousands of calls over high speed (2.5 and 10Gb/second) network links. The network also uses class of service and many other configuration setups to ensure a consistent quality of service for the traffic flow. You can be sure everything will be massively resilient. In addition this traffic won't traverse the public Internet at all, but will be on a private network (though gatewayed to the Internet for connectivity to other services). This will allow BT to guarantee they wont be hit by Internet related issues like congestion, black-hole routing and so on. Dont compare this service to public Internet VoIP, its NOTHING like it.
Personally I think this is a fantastic move, and will really help the UK take advantage of up and coming technologies over the next decade.
PS there is already an Internet standard to map IP addresses to public phone numbers, and there is also work on integrating VoIP into the DNS infrastructure!
