The topic isn't about Pipex specifically, I only mentioned them in the post as they are who I chose as my DSL provider. |
Re: Want ADSL?-Read on....
Maybe this thread has highlighted a need for a new forum category?
How about Alternatives to ntl ? :D |

Before i switched to the other side i could only check that the local BT exchange was adsl compatable by typing in my postcode This method is only 80-90% accurate (typing a phone number is more accurate) the reply i saw said : "Good news! The checker indicates that ADSL Broadband is available in your area and that the preliminary check on your postcode suggests that you should be able to receive ADSL Broadband services at speeds from 512kilobits per second to 2Megabits per second downstream and 256kilobits per second upstream" i guess when typing in a phone number will bring up something different? I guess Bulldog must have a special arrangement with BT as no other adsl isp offer the same service packages. There are some pitbull falls with bulldog that could be highlighted a deciding factor if Dr. Plummer decides to create a new forum catagory. :) Quote:

Though it is more accurate as they can give you an idea of your own line rather than just a guess based on your postcode. Quote:
In their view they are mainly a "business" ISP - thus they have loads of spare bandwidth and can afford "cheap" off peak tariffs for residentail customers - thats the theory anyway. |

A number of ADSL ISPs offer similar 2Mbit services from a number of enabled exchanges using an alternative form of ADSL provisioning called 'DataStream' or Option 3 in BT speak, have a google :p Quote:
Not all BT exchanges are equipped equally, they have varying backhaul depending on demand and other factors. Typical backhaul is 4 - 8Mbit for 512k 50:1 users and 10Mbit for 20:1 business users, not sure what is provisioned for 1Mbit users, think they go on the same paths as 512k. This only applies to IPStream not DataStream, which uses a dedicated ATM link from each exchange onto Bulldog's ATM network, rather than having the data go to BT's LAC (L2TP Access Concentrator) along with the other IPStream ISPs on an exchange and get seperated there to be fed to the individual ISPs. Bulldog's DataStream links typically vary between 2Mbit and at most 10Mbit, which in some cases works rather poorly, when there are 2 or 3 2Mbit users on an exchange intent on anhialating the 2Mbit VP (Virtual Pipe/Path) and said path only delivers 1.8Mbit of actual usable data speeds get a bit hairy. That is how Bulldog delivers their alternative services on 450 or so exchanges in the UK. In the 70 or so (I think) in Central London they actually use all their own kit. People's copper phone lines come in and go to Bulldog's own DSLAM (Digital Subscriber Line Access Multiplexer) - the bit that combines all the incoming ADSL 'calls' into ATM for backhaul, and from their goes down Bulldog's Metronet. As Bulldog have complete control of this apart from the copper itself and the line card at BT they can offer whatever they want on it, DataStream and IPStream are limited by BT to 2048k/256k maximum. Usually LLU (Local Loop Unbundled or BT speak DSL Option 2) exchanges are on 100Mbit LAN Extension lines ;) And that's it in a nutshell, albeit a large one, hope that helps *phew* Without having to google once ;) *flex* |

As problems appear Bulldog increase capacity from that exchange and resolve them though a few people find their problems don't get fixed and then Bulldog seem to release them from their 12 month contracts. Personally, as I said I find it excellent value - if you have any Bulldog specific questions - drop me a line just in case we bore everyone else here :) |

I was keeping things simple and only talking about BT's own kit at the exchanges using IPStream, not the 35 Bulldog have LLU'ed in Central London or the fact that Bulldog sometimes use BT DataStream (though I did mention that Bulldog use a different form of backhaul as a reference) to operate the the Primetime service BT IPStream exchanges have "sufficient" backhaul to BT's core network - the amounts differ according to the number of customers buts its more than sufficient Bulldog uses BT DataStream as you correctly say and that can cause problems sometimes which is why Bulldog increase capicaty etc as I have also stated. BT DataStream can only go up to 10MB per Virtual Circuit but Bulldog sometimes have more than 1 going to an exchange (they must have quite a few customers on those!) or so I have been reliabilty informed. On the 35 exchanges which Bulldog have LLU'ed (central London only) a its all their equipment they are now offering up to 8Mb lines... Hopefully as some of the DataStream exchanges get busier they will LLU them as well. Easynet are the only other people really doing LLU in abig way (more exchanges than Bulldog) but they are not offering residentail services yet - but they will be next year sometime from what I have been told |

Tricky the extra LLU as Bulldog at the mo only have a Metronet AFAIK. Yep heard that too, they are taking orders to guage demand for their services on all exchanges, IPStreamed up or not, and this is I think a precursor to offering residential services. Mmmm 8Mbit/768kbit :romance: |
