If I may without giving offence just give a slightly different viewpoint
"Initially when other providers were allowed to compete with BT they made them put in their own equipment at the exchange and rent the space which restricted the availability"
Not true Bt were forced to provide space in their own premises for equipment that the other service provider choose to install.
"To improve competition regulations were changed and now the other providers can rent a block of BT equipment" Other service providers were and have always been able to wholesale from BT and retail on ADSL and VDSL especially in smaller exchanges where it did/does not make economic sense for them to install their own equipment.
"Some of the equipment is now miniaturised and distributed in to the roadside cabinets and the connection to the cabinet from the exchange is fibre optic."
Not quite correct. Whilst there is some condensing of space depending on the type of line card fitted 24 or 32 port it would hardly be referred to as miniturised it is still a DSLAM shelf.
"This used to be deceptively advertised as a fibre service" I agree in part but I don't think it was deceptive more misguided. "Still uses the same wires though which are managed by Openreach. You don't see them stringing a new bit of wire each time someone changes provider." That's what made it economically viable in the short term to supply faster speeds.
"The equipment is the same" No it isn't, The original iteration of ADSL was up to 8mB and went through upgrades to ADSL 2+ to give up to 24mB the emphasis with all ADSL is UP TO but never quite achieving. The new VDSL dslam will give about 110mB at the dslam so the closest people will get 80mB which is the top cap.
"probably less than 3 years old" No the original DSLAMs installed were ECI and some have been in place for at least 6 years" and "probably still BT owned" No Mostly but not exclusively all DSLAMS are owned by Openreach All that happens is some software settings are changed so max rate and contention ratio applied to your line is changed and the billing software changes.
"If you move from wired to fibre to the home the equipment and the 'wire' has to change so that is the big opportunity to really improve. Be aware that FTTP stands for Fibre to the Premises from some suppliers but used to be Fibre to the Pole from BT so you might still get wire for the last stretch."
There seems to be confusion here. It is quite simple an FTTP product is a fibre in to the premises. Now on a new building site if the developer buys into it FTTP is all you will get. But regardless of that the final fibre connection will be into the home and connected internally to a fibre router. Where there is a copper network then aa hybrid arrangement may occour but if the fibre block is at the top of the pole then a fibre or fibre/copper dropwire will be run into the primises and the fibre will once again go into a fibre router but the telephony could be on the copper totally seperately.
