I read that as "no authentication used" ie if you're wired to a TalkTalk DSLAM you just connect regardless.
All people on TalkTalk wholesale would have unrestricted access to TalkTalk retail's network then?
I don't know and can't test, all I know is that any and no credentials gives a talk talk retail line a working broadband service - I first found this out by using a BT Home Hub to fault find on a TT retail line.
If you have a TT retail line you have a retail broadband service on tap it appears.
Can't say what happens for TT Wholesale customers, whether circuits are setup differently and allocated to different authentication regimes. The authentication might be used to allocate an ISP address from the Retail ISP I suppose.
Last week I took an AOL router home to test and it synced up and logged into AOL via a 21CN BT connection so they don't appear to be limiting the user logins you can apply.
