This is what 21CN is

21CN means 21st Century. It is BT's grand plan to move its network from AXE PSTN to Protocol (IP packet), to be 50% complete by 2008 and secure savings of £1,000 million per year (good dividends for shareholders) at an investment cost of £10,000 million over 5 years. ADSL2+ was intro'd Sept 2005.

Those who are having grief with their now dysfunctional ADSL2+ equipment (as I am) should not anticipate BT replacing it for them so they should buy new routers (as I have today) and look happy about being allowed to underwrite their suppliers costs and assist with BT shareholders dividends.

Actually it's 21st Century Network

It's up to the ISP to replace the router, not BT.

What has dysfunctional ADSL2+ routers got to do with 21C Network particularly? Equally applies to LLU!

The move from PSTN to IP in the core is actually nothing to do with ADSL2+ performance.

My old analogue mobile phone got replaced by a GSM, was there any compensation, no. My TV needed a freeview box, was there compensation no, I needed to adjust car engine timing when unleaded fuel was all that was available the list goes on.

If you want an evaluation of the ADSL modem, then hawk it round to some others who have ADSL2+ (I presume you did upgrade its firmware to the latest version, as this will often remove bugs).

If you wanted to remain on ADSL only you could have requested an ADSL only up to 8Meg profile from Zen.
