Enabling ADSL2+ for the Harbury exchange (CMHARBU)

[link to this post]

I have noticed that my local exchange is due to get upgraded to 21CN WBC this year, but different sites provide different dates. Can anyone help me work out which is the correct date?

The BTwholesale availability checker states 31/05/2012.
Your exchange is planned to have ADSL2+ by 31st May 2012. Our test also indicates that your line currently supports an estimated ADSL2+ broadband line speed of 3Mbps; typically the line speed would range between 1.5Mbps and 5.5Mbps.

But and give 30/03/2012. Any suggestions as to which is correct?

Finally, given the following lines stats, what impact would you expect that I would see of the upgrade to ADSL2+? I have heard that I can not expect much on the downstream, but it would be great to get some improvement on the upstream.

I am currently synced at 4544/448Kbps.

ADSL Settings

VPI/VCI 0/38
Type PPPoA
Modulation G.992.1 Annex A
Latency type Interleaved
Noise margin (Down/Up) 5.6 dB / 20.0 dB
Line attenuation (Down/Up) 51.0 dB / 28.5 dB
Output power (Down/Up) 7.5 dBm / 1.6 dBm

Thanks, Matt

You will not benefit from ADSL2+ on Down but your Up should increase to over 1 Meg. However you may find you are better off on ADSL2.

BT must know most about dates, but they are only plans.

1999: Freeserve 48K Dial-Up => 2005: Wanadoo 1 Meg BB => 2007: Orange 2 Meg BB => 2008: Orange 8 Meg LLU => 2010: Orange 16 Meg LLU => 2011: Orange 19 Meg WBC
