Re: The BT FTTC line stats thread


[re: MrSaffron] [link to this post]
 
In reply to a post by MrSaffron:
"This will be native PPPoE rather than a mass of encapsulation on encapsulation and supply a 1500 byte MTU to end users. "

Was thinking of the fun when you start getting LLU providers involved who seem to randomly alter the MTU on their networks, and people confused over what to set on their PC.

Will have to drag myself to some BT demo centre to have a play one day I guess.


Shouldn't be an issue, MTU is part of PPPoE negotiation and networks should be happily able to carry jumbo frames right up to the BRAS where the encapsulation is stripped or will adjust MTU with client to 1492 to allow for the 8 byte PPP header.

Certainly it doesn't seem to be an issue for the Far Eastern networks though it's noteworthy that there have been a few issues here and there with Verizon FiOS before it was converted to DHCP.

It should also be noted though that all of the current connections are through BT Wholesale, so the requirement for PPPoE will be from BTW in order to separate connections between wholesale customers on their BRAS and customers' LTS. The BTO product supports DHCP and no reason why LLUOs can't use DHCP as indeed Be/O2 already do.

Sorry to hijack the thread back to it's original purpose wink

I've had my line regraded from Total BB Fibre (2Mbps max up) to Fibre Plus (10Mbps max up) and now I'm getting [from best speed test results];;

37.6Mbps Down
8.4Mbps Up

Again, distance from cab. ~200-300 metres.

Just had FTTC installed this morning.

Looking good smile

http://www.speedtest.bbmax.co.uk/results.php?t=12718...

Date of Speed Test: 2010-04-21 09:49:47
Download Speed: 37453 kbps (4681.6 KB/sec transfer rate)
Upload Speed: 8242 kbps (1030.3 KB/sec transfer rate)

I don't have a router to hand so i'm just using PPPoE via the PC direct to the modem.

Finally got FTTC installed this morning.
BT Engineer was great by the way... really nice guy... (they had some problem in the PCP - where they had mixed up the D & E side cables from the FTTC Cab but he spotted it and now I am connected)

Speed from test equipment ..
40Mbps Down i.e pretty much no loss from PCP which is great.. I am about 400-500M from it.
I forgot to ask the UP speed but I am guessing it would be around the 15 as other have reported.

Attenuation was 16.2db and 10.9 SNR..
I am getting between 30 & 32 Mbps throughput and about 8Mbps up. It may improve if the SNR Margin drops down. (Thats if I assume it works like ADSL and has a training period).

ADSL Checker said 19 and 7 for me..

So far its great especially the up speed when sending work emails with large attachments.
