Jeff.....so you believe this is likely to be an ISP equipment issue ? I've had TT conduct 3x line tests in the last 3 months, 2 have passed, one has failed with an "earth" fault. TT have confimed this test/fail result as it's recorded on my "notes". I have advised the fault as intermittant - to me that seems conversant with the 2x pass 1x fail results logged. The drop-out at 16:40 was when I switched from G.DMT to ADSL2+. I don't seem to have the option to log date on the graphs (Routersta LITE limitation I guess)
If the visit finds no internal fault, then it's escalated to BT to check line/exchange....but where does TT's own equioment come under scrutiny as a possible cause ? If it is incorectly set-up provision, at what point will this possibility be investigated ? I think I now understand that my previous Orange provision used BT Exchange equipment, whereas the TT ADSL2+ LLU now uses TT equipment - is this correct ? If so, is this equipment loactaed in a TT switchroom somewhere, or is it located in my local BT exchange ? I'm surpised that the possible cause has only ever been discussed as a BTline/exchange issue or a residential wiring/equipment issue......where does TT's own equioment come in the chain of provision ?
Just found this on Wikipedia - could this mean that I'm actually connected to out of date/troublesome/unfamiliar AOL or Tiscali equipment ?
As of 14 January 2006, 210,000 local loop connections had been unbundled from BT operation under local loop unbundling. Ofcom had hoped that 1 million local loop connections would be unbundled by June 2006. However, as reported by The Register, on 15 June 2006, the figure had reached only 500,000, but was growing by 20,000 a week. Ofcom announced in November 2006 that 1,000,000 connections had been unbundled.[4] By April 2007, the figure was 2,000,000.[5]
By June 2006, AOL UK had unbundled 100,000 lines through its £120 million investment[citation needed], making it the largest single LLU operator in the UK market[citation needed].
On 10 October 2006, Carphone Warehouse announced the purchase of AOL UK, the leading LLU operator, for £370m.[6] This makes Carphone Warehouse the 3rd largest broadband provider and the largest LLU Operator with more than 150,000 LLU customers.[7]
On 8 May 2009, TalkTalk, who are owned by The Carphone Warehouse, announced that they would purchase ailing Tiscali UK's assets for £235 million. On 30 June 2009, Tiscali sold its UK subsidiary to The Carphone Warehouse following regulatory approval from the European Union. This purchase made TalkTalk the biggest Home Broadband supplier in the UK, with 4.25 million home broadband subscribers, compared with BT's 3.9 million. The service was rebranded as TalkTalk in January 2010.
Most LLU operators only unbundle the broadband service leaving the traditional telephone service using BT's core equipment (with or without the provision of Carrier preselect). Where the traditional telephone service is also unbundled (full LLU), operators usually prohibit the facility where selected calls can be made using the networks of other telephone providers (i.e. accessed using a 3 to 5 digit prefix beginning with '1'). These calls can usually still be made by using an 0800 or other non-geographic (NGN) access code.
