21CN WBC Status question

Hi All

My exchange according to SamKnows says RFS 31/3/2012 but I thought I would see what the BT Boradband Checker has to say about the phone number and got this (copied of the page report)

==================================================================

Your exchange is ADSL enabled, and our initial test on your line indicates that your line should be able to have an ADSL broadband service that provides a fixed line speed up to 2Mbps.


Our test also indicates that your line currently supports an estimated ADSL Max broadband line speed of 2Mbps; typically the line speed would range between 1Mbps and 3.5Mbps.


Our test also indicates that your line currently supports an estimated ADSL2+ broadband line speed of 2.5Mbps; typically the line speed would range between 1Mbps and 4Mbps.

===================================================================

FWIW I am currently on Max ADSL sync'ing at 3648kbps with this test result:-

And the TBB test slightly different speed?




So based on the BT checker is my exchange already ADSL+2 enabled and would I benefit from the switch to it???

If that was really meant to be a question: The estimates are of connection/sync speed but the speedtest is of actual throughput, usually about 83% of sync.

The BT chacker indicates that exchanged is 21CN. At those speeds you will not benefit from ADSL2+, except your upload speed should increase. However, you may gain slightly from ADSL2 only.

Post your router stats so we can see. Your speed indicates an attenuation of about 55 dB.

I don't think that BTW report necessarily means that ADSL2+ is enabled. For exchanges that are scheduled for FTTC but not enabled, users get their FTTC estimates with exactly the same wording.

If you put your phone number into the IDNet checker on this page see which package page it takes you to.

Stats here:-

Uptime: 7 days, 9:06:05

DSL Type: G.992.1 annex A

Bandwidth (Up/Down) [kbps/kbps]: 448 / 3,648

Output Power (Up/Down) [dBm]: 11.5 / 19.0

Line Attenuation (Up/Down) [dB]: 31.5 / 54.0

SN Margin (Up/Down) [dB]: 20.0 / 5.5

So if ADSL+2 has the potential to give me some improvement will PlusNet CSC be able to tell me if my exchange really is enabled as the BT checker seems to suggest? The checker infers in best case scenario I will get another 0.5Mb in download assuming I am reading that right???

Maybe I should PM Orbey and see what he can tell me about it

Hi Roberto

Using the checker on the link you give it 'returns' only ADSL Max packages, so why the variance with the BT's own checker??? Does seem sort of misleading

As I said, the BT Wholesale checker doesn't say it is live. It just says "your line supports", ie when the exchange is live your line is OK to get it.

OK but the same phrase is used about ADSL Max and I already have that service so by inference the ADSL+2 functionality is there, hence why I said the report is misleading???

No! A few months ago before FTTC came to a cabinet near me. BT checker said something like "FTTC estimated to be available on {date} ...".

@ OP: Don't rely on BT Checker being accurate to 0.5 Meg. You already getting above top of its range!

True, but in earlier days it was the same. Even with the current wording I think it still says "supports". Not "will support".

Unfortunately SamKnows is behind on the latest information from BTw (BTw closed the page where SamKnows used to get the latest Datasheet showing what exchanges are due and which are enabled. However, the document can be obtained elsewhere).

I doubt you would get much out of ADSL2+ with your attenuation though.

I might also add that it could be some time before BTw accept orders for 21CN on your exchange if it has been enabled.

For example: My exchange was enabled for 21CN early January and the earliest time BT Retail are letting us renew our contract is next Tuesday (21st February), when they say the line will be switched to the new equipment.
