Hey slowcoach, I bet your landlord makes a nice profit of you everytime there is a post you probably run to the pub for a quick pint to get the latest news on NTL and then run back again

Dont we all

I just spoke to NTL through customer services, and they say i should be on 10Mbit by October so whoever lives near North Manchester, which is the Bolton/Bury way you should have around that time aswell.

I thought customer services were shut on sundays?

Anyway....do u think they will start rolling it out at the same time as telewest?

Ok taking in what ignition said about the 4 users maxing the ubr, and a few other thoughts, I have serious concerns about quality of the connection.

On the current tier levels the contention at ubr level seems to work out at under 20:1 which is quite acceptable. But with everyone on 10mbit that could mean contention of around 50:1 (based on around 200users on a ubr) ubr specs here I think ntl use eurodocsis http://www.cable-modems.org/standard...comparison.pdf .

Now if any ntl bod can confirm, on the new speeds will effective contention ratio be around the same or am I right there is a marked increase, and if so will there be traffic shaping to protect gamers and people using live apps from latency problems.

they use both, depends which platform there on, langley or bromley, i think it was bromley, that use eurodocsis, sure ignition will confirm, or deny!!

Original ntl areas - DOCSIS
Ex C&W areas - EuroDOCSIS

Chrysalis · 23-08-2005, 00:28

Ok if anyone knows what area LE3 leics falls under would appreciate it. Normal docsis would be higher contention then 74:1. Requiring 3 users to max it out unless they got the 256-QAM 42mbit. I am looking forward to the speeds but its quite scary how fragile this is for capacity problems.

(above based on 200users on ubr someone correct me if I am way off)

Most BB users will only be doing one thing at a time with their connection so will never use anything like the 10 Mbps. Even if they connect to a server which can give them the full 10 Mbps they will probably get whatever it is that they are downloading in just a few seconds so won't put undue pressure on the network. Even if their connection slowed down quite a lot they would probably never realise that it had. It's the experienced heavy downloaders that will put pressure on the system who may move on to pastures new if they find themselves restricted or may find that their upload restricts them.

leicester comes under the Langley platform / headend, so you will be docsis.

if you get a choice of BB through STB or CM, then you are Bromley ( euroDocsis )

Just through a CM then you are Langley ( Docsis)

per channel maybe, not per ubr,

Plus you also have to have STB's connected to UBR's as they all require ip addresses & connections for the limited I/A services.

im in bromley and have a cable modem. What is the difference between euroDocsis and docsis and which is better?

Also the good thing about 10mbit is if someone asks you what speed is your internet you can casually say "10mbit", what about you?

Sorry if this has already been asked but I have looked and could not find a similar question anywhere here.

I have the ntl250 cable modem will this run at speeds of 10mb?

You'd be surprised how well this actually works, just to remind services will be capped, which helps, could easily enough be traffic shaped to protect real time services, and I've seen services working quite well with over 200 modems on a 256QAM downstream, as high as 1000 infact, these modems mostly being 5.5Mbps/640kbps and 10Mbps/1Mbps.

Usage patterns do vary though, some cards have 200 modems on them and average less than 4Mbps downstream throughput, others get nearly maxed on the same number of modems now.

The joys of capacity planning, capping the 10Mbps will help a lot though, TW will get slaughtered in student areas especially, such as for example Leicester with De Montford, etc in that area

If it's any comfort to you a load of new kit has gone into Leicester, it's now one of the best provisioned areas for bandwidth per modem on the network if not the best, and more to come, so relax!

DOCSIS uses 6MHz wide channels yielding potential throughput of 27Mbps or 38Mbps depending on how dense the modulation used is.

EuroDOCSIS uses 8MHz wide channels yielding 38Mbps or 51Mbps depending on the modulation density.

So EuroDOCSIS is the better of the two from the downstream point of view, however with increasing upstream demands its' inate higher asymettry can be 'an issue'.

EuroDOCSIS is the daddy though, especially EuroDOCSIS 2, which is happily powering the UPC 24Mbps/8Mbps service in Sweden
