It is nice when it does happen.
It's been 2 weeks now and being able to watch Iplayer HD and lovefilm streaming without any stutter is fab.
Bit envious of being able to see stats, ECI modems are being problematic I hear.

just out of interest, why does your modem say it's annex b - i thought the standard in the uk was annex a, annex b being used in central and eastern europe.

VDSL2 is Annex B now.

As in legacy ADSL and ADSL2+, VDSL2 includes regional bandplan annexes that specify PSD Mask for numerous regional bandplans and are designed to provide coexistence with other services. Annex A specifies bandplans for the North American region and enables VDSL2 to be deployed with traditional POTS telephony or in an all-digital mode (similar to Annex J in ADSL2). Annex B specifies bandplans for Europe and enables VDSL2 deployment with underlying POTS and ISDN services. Annex C allows VDSL2 to coexist with TCMISDN services, found primarily in Japan

Very nice too ! I seem to recall that you were within spitting distance of the cab.

No chance that your router shows a bits per bin graph ? Also do you have a 'before and after' for that ?

Yes, the cab is just across the road.

I did start the graphing tool that has been released for the Openreach HG612 modem, so I have some images/graphs/data from before and after - what in particular are you looking for?

Just interested, no 80/20 circuits round this way AFAIK, I was presuming that it just occupies more of the higher bins, and wondered if this was right.

I've got two more FTTC lines going in tomorrow/Wednesday, so will also be (MLPPP) bonding the lines to see if we can get over 100Mb

Around 4-5 Mb but they were so unstable it sucked. We've gone from 4Mb to 75Mb in two days laugh

We now have 3 FTTC lines installed.

2 are on 80/20 and 1 is on 40/10.

We're testing the (MLPPP) bonding of the 2 x 80/20 lines and at present are just scraping 100Mb downstream and 30Mb upstream throughput:

http://www.speedtest.net/result/1818623063.png

The attainable rate has dropped since all 3 lines have been installed, evidence of some form of crosstalk etc, but on the 80/20 lines it still shows:

Downstream Upstream
Attainable rate (kbit/s) 129948 41437
SNR margin (dB) 19.9 19.6
Line rate (kbit/s) 79999 20000

Looks like you're losing an awful lot of throughput somewhere along the line?

Yeah, it could be that the box we're using as the router to bond the lines could be struggling (even though its a Linux PC so decent spec, with gigabit cards inside)... as it won't creep above the 100Mb mark.

Either that of or the speedtest isn't coping.

May only allocate 100Mb to a test at max.

speedtest.net should handle near 1gbit/sec - although I guess it depends on which server you're testing against?

Nice roughly half my line attenuation 100 meter line?

I think crosstalk will in time chop some of that max rate down, but hey there is plenty of it laugh


heres my stats with a fullish cab and 300 meter line.

Yeah, I think it may be a limit on the Cisco port or something at the network centre as in reality the MLPPP bonding has never ever reached 100Mb before (bonding ADSL links) so it could be that the port is limited to 100Mb. We'll find out either way smile

Is this what you are using?

CCS Power Router will bond to speeds of 100Mb/s

[re: madnutter56] [link to this post]
 
On our side we're using a Linux PC 9acting as a router) with 4 Gigabit LAN cards.

So its no limitation on our side but could be on our suppliers side where the lines terminate at the LNS on the Cisco routers they use to enable the MLPPP bonding service.

I'll speak with their NOC tomorrow.

Indeed - I find that the "Trance FM" server in London, which is the one it wants to use for me by default, can't handle more than about 40-50Mbps, so I have to use a different one.

[re: Adsl24] [link to this post]
 
James,

I have posted a ticket with ADSL 24, please could reply/explain what process of bonding you are using.

I am currently looking into buying a router of some form - Am I correct in saying that the Routerboard would not be sufficient if I were looking at 80/20 x2?

Is there a simpler solution than utilising a PC with Linux as you are, in order to get the desired throughput? Would a router like the cisco dual WANs be appropriate, or are these just for resillience/load balancing.

Cheers

Do ADSL24 support per packet bonding? And what are the pros of utilising MLPPP on your linux based PC/router over a dedicated device such as the firebrick 2700?
