Talk:BT 21CN

message: I've just done a quick re-write of this.  I used to work on this, so I do have some background.  I've tried to include the publically known information whilst being neutral in the phraseology.  I think the nodal concept is one of the key aspects of 21CN, and shouldn't be lost.  --Phil Holmes 22:13, 31 January 2006 (UTC)

message: I'm opposed to this as it stands. Most of the "facts" on the other article are wrong.  It would be better to merge the 2, but only after heavy editing of that page. --Phil Holmes 18:00, 19 July 2006 (UTC)

message: Is there a reference available for "In July 2007, Sir Christopher Bland..."? Hikari 08:54, 8 August 2007 (UTC)
replies: text: Sure.  I've just added one.  It was top of the list when typing "bland fibre" into Google, so you could have added that into the article. --Phil Holmes 11:27, 8 August 2007 (UTC)
thread_title:  Reference 

message: Under iNode, the article states:
" BYB501 AXE10 TSS (Telephony Softswitch Server)"
However, TSS does not stand for Telephony Softswitch Server, and the AXE-10 is not only not a softswitch, or an IP switch, or even an NGN device. It's also interesting that the BT 12CN project is essentially BT's implementation of an NGN network, but NGN and its underlying concepts aren't mentioned.
TSS stands for "Trunk and Signalling Subsystem". The AXE-10 is a circuit switch. It doesn't do IP. This is the switch that will be replaced by a softswitch.  —Preceding unsigned comment added by Narcogen (talk • contribs) 06:47, 30 July 2008 (UTC)
replies: text: I'm not an expert on the 21CN switching technology.  However, I note that the article says "The iNode is built upon the BYB501 AXE10 TSS" not that it is a BYB501.  My assumption is that this means that the BYB501 is the basis for the softswitch, not the actual switch itself.  If you have a better understanding of the technology used in the iNode, then go ahead and edit the article.  Ditto on references to NGN. --Phil Holmes (talk) 08:29, 31 July 2008 (UTC)

text: Not really.  The speed of data from the server to your house is determined by the slowest section of the route.  So - if the slowest section is the last mile (or few miles, in all liklihood), then that is the speed you will see.  All other things being equal, it is highly likely this will be the slowest section.  --Phil Holmes (talk) 16:34, 21 September 2009 (UTC)
thread_title:  Factchecking 

message: What is the history of this project? Specifically, when did BT make the decision to move to an IP-based NGN and what did the regulators and politicians have to say about it? MarkMLl (talk) 13:11, 25 September 2008 (UTC)
