>>> There seems to be no charge if the user "migrates" like move house/phone and stays with bt yet the......There is a BTw charge for both new connections and migration. Some ISPs do pass on this charge to the customer, but a lot of ISPs pick up the tab in order to encourage you to go with them.
I cant comment on the VAT element, but it would appear most ISPs seem to pass on the fee as £30 - aside from Plusnet who pass on £25
>>> where I lose it is how does this apply to doing something to telephone/internet equipment somewhere.It may help if you have a look
inside the BT exchange.
When you get adsl broadband, a BToR Frames engineer will wire up your line from the MDF on to an ADSL panel block (patch panel). Which panel your line is wired up to depends on which type of adsl you have ie LLU such as TT, Sky etc often tend to all be grouped on their own same patch panel. It doesnt matter so much with BTw based ISPs such as BT, Plusnet, Zen etc as they will use the same BTw MSAN.
>>>> Are these ties very expensive?In the context of what Im about to explain below:-
~ The tie pair is the BT name for 'your' pair of wires at the exchange from the MDF and on to the adsl equipment, such as the DSLAM/MSAN or handover frame.
~ Jumpers is the wiring into the patch panel.
------
AFAIK the PSTN (telephone voice) can be ceased automatically, as can in '
theory' the ADSL... but......
..... and here comes the but... (I stand here to be corrected by BlackSheep as hes our resident BT expert).....
At about the time that BTw introduced the cessation charges there were a lot of problems with LLU ISPs having 'Tags' on the line and this was causing huge problems during migration. A TAG on the line is when an ISP hasnt released ownership of the adsl aspect of the line and that ISP is said to own the line.
If a line wasn't ceased correctly, then it was still possible to attain a sync because your tie pair is still connected to the patch panel.. and on to the relevant DSLAM/MSAN.
You would not have full internet access though because either/and/or the ISP hasnt authorised you on to their network or in the case of BTw you are not authorised at the
RAS (which is where most of the automatic stuff happens).
So what could happen is that when you cancelled your adsl, your line could still be wired up to the patch panel - this is known as Jumper in Place (JIP)... your line could be hooked up to say a TT patch panel for ever more, even if you may have cancelled your adsl with TT.
If you were migrating, then this wouldnt matter because on that day the BToR Frames guy takes your pair from the TT panel and moves it over to say the BTw group of panels.
Even today there is the odd occasion where a delay in connecting up a new adsl connection could be subject to problems or delays because the Jumper is in Place on say an LLU ISP's panel. Obviously this wouldnt cause you a problem as you have moved away and dont care.. but the new house owner may not be so happy if they are trying to get DSL but another ISPs tag is on the line for that phone number.
There were also a few occasions where some exchanges had problems if Jumpers were left in place and not enough patch panels - or spaces on the patch panel - for new DSL subscribers. Insufficient Patch Panels still can on occasion cause problems and delay.
I believe that even newer technology has fairly recently been introduced to help overcome such problems... but rolling back the clock to the period when the cessation charges was introduced, LLU was in its infancy and many of us on here will remember just how hard it was to move between certain ISPs and how often it all got mucked up... and how hard it could be to get tags removed.
Hope this helps make things a bit clearer, and no doubt BS will be able to correct if I got anything wrong.
