Though, surely I am right in saying 21CN WBC is a prerequisite?

No, it isn't a prerequisite.  :)

As an example, N*Star's current situation shows it quite clearly. For the serving telephony exchange, the Magenta Systems CodeLook page shows --

Locality:       Helens Bay, Bangor, County Down   All Post Codes
               
Country:        Northern Ireland           Post Code:        BT19
20CN IPStream:  ADSL                       21CN WBC:         None
Fibre:          From 26th August 2010      Type:             FTTC, FoD

BT Exchange:    Helens Bay                 Exchange Code:    NIHB

Notice my emboldening. The fibre head-end exchange is Bangor, NIBA.

What should I set mtu to?
Also, what should I set these to

I would set the MTU to the maximum that the Billion 8800NL allows.

As for the other parameters on that page, leave them all as they are currently set.

Is that 1492, 1500 or something else?

I mean, for the exchange which is the "fibre-head" exchange it needs 21CN WBC first?

Is that 1492, 1500 or something else?
From the two devices that I own from Billion, I believe 1492 bytes is the max.

Tick G.DMT and ADSL2 in hope, some day. Untick ADSL2+. Tick Bitswap and SRA, in hope, again. Tick 'Trellis' if it is there. Choose PPPoA not PPPoE and choose VC-MUX as opposed to LLC wherever that is.

Ah, I see. My apologies for misunderstanding.  :-[  In truthfulness, the fibre head-end does not need to be an exchange building but it would certainly be simpler if it was! In the case of an exchange based fibre head-end I would be surprised if the telephony side was not based on 21CN WBC.

I wonder if either Black Sheep or I*net could offer a few words on the subject?

I think I am confusing it more than necessary, so perhaps it should be its own thread in reality. I just thought that for FTTx to be provided, appropriate network backhaul (the enablement of 21CN WBC) was required beforehand.

Someone please correct me in 3...2...1...  :)

Definitely go with 1500, that is what I use.

He already uses 1500, 1492 is a PPPoE limit.

Assuming your PC is running Windows, change its MTU to 1500 with TCP Optimizer. Tick "Modify All Network Adapters", tick "Optimal" at the bottom and click "Apply changes" & "OK", but say "No" to restart prompt, and close TCP Optimizer. Then, re-open TCP Optimizer, tick "Custom" at the bottom, in the "MTU" box enter "1500". I've also attached a picture of what the other settings should be, but a note about the "Disable Nagle's algorithm" section in the "Advanced Settings" tab - leave them on "default" (explanation). I've disabled both Nagle algorithms for minimum latency (gaming), but it's not good for data transfer (streaming). The rest are ideal for you. After you're done click "Apply changes" and restart your PC for it to take effect.

To test if 1500 is working on your PC, open a "command prompt" and you should get similar results:
Code: [Select]
ping google.com -l 1472 -f

About SRA, just keep it unticked. give unticked a shot, and see whether you have more de-syncs (dropouts).
It isn't supported on ADSL [just ADSL2], and it's always better to have it off when not supported. People had problems with it enabled in the router because of its router implementation, like not syncing or line problems.
When you get ADSL2 this year :fingers:, if you'll have line drops, you could try ticking it (there's a chance your exchange wouldn't support it though).


I hope you ticked Firewall in the ATM interface. Also if you want you can screenshot any or all the router pages and I'll say which settings to use.

Use a quality faceplate type filter (jargon: an SSFP) instead of the dangly ones. The BT Pressac ones are excellent.

If you have no (traditional, wired) phones and no extensions then you don't need a filter even. (I don't.)
