Chris,
I know well in respect of ADSL that one line can indeed be markedly different from one door to the next using the same cable bundle. It comes down to just how good a particular d-side pair is; getting a good one can be a lottery and sometimes it can be a matter of accepting the best of a very band bunch. A poor pair can be still be "within specification" but that is solely down to BTOR specs being so wide that in places you could dive a bendy bus through them sideways on.
I do not imagine that matters are any different in respect of the d-side for fibre, however unlike ADSL BTOR have made sure that users cannot get at the raw line stats, so that they have no means of measuring service quality. How can one be sure that the d-side is the best it can be, as opposed to defective but within specification? Cross talk, arising from poor quality d-side circuits, is a well recognised issue impacting fibre speed performance.
What is the VOICE noise level like on this user's copper pair? How much better is (in fact) the next door neighbour's line and just why will BTOR not provide a d-side pair of similar quality, if there is indeed a quality difference?
I think we are seeing far too much variation arising from poor quality BTOR d-side pair infrastructure which they are unwilling to put right. Unfortunately, subscribers see this as a provider - that is a PN - issue and believe (wrongly) that changing providers will deliver a better service. Sadly unless that provider is Virgin, with their own non-BTOR infrastructure, this is not likely to be the case. The same defective BTOR cables used by a different provider will deliver the same sub-standard performance IRRESPECTIVE of who the user pays their bill to.
When will the 'new' CEO of PN take BTw / BTOR by the scruff of the neck and get a better service provision for PN users?
Superusers are not staff, but they do have a direct line of communication into the business in order to raise issues, concerns and feedback from the community.
