Two ADSL lines into a single PC?

Could someone kindly point me to where I can understand the ins and out
of having two network cards in a PC and feeding them with two ADSL
lines.

Could somehow a PC on the network access both lines? Would each PC need
a second card?

Just curious, but why on earth would you want to do this..?

I think it's doable, but lots of fun with trying to balance the load
between the 2 connections would ensue.

You can connect a PC to two networks, but it will only access the net via
one at the time, you need to tell Windows software which one to use.

If you seeking a faster / dual connection, aka 'bonding' this requires
special equipment at the BT exchange and on your PC.

I've got it here, although it's between a cable line and an ADSL line. Just
put an old PC (mine's a 200MHz Pentium) with three ethernet cards running
Linux in the setup. It connects to both external lines and can provide
load-balancing and firewall protection. I wouldn't try it with a Windows
machine though.

you would need a load balancing router/modem, ADSLGuide has an example
on their review page. It combines two lines into service for a single PC
or network.

Doing it any other way would be extremely difficult

done correctly you get double the upload and download speeds, the
former in particular being of interest with the current BT speed
portfolio. For this you need MLPPP to bond two or more lines in the
same way that 128k ISDN works.

Griffin and Nildram also do MLPPP. You need either a fancy router of
build one yourself using Linux and two PCI ADSL modems with a free
bootable CD from http://www.freestuffjunction.co.uk/bondedcd.shtml

Two lines from two ISPs can also be used separately into one LAN or
potentially into one PC if you get to grips with routing tables etc to
utilise both lines fully.

new maxDSL products should have a better upstream, released in 2006.
Which would make the exercise a bit pointless, when waiting a while
would bring the same result. At most a bonded service would give 512Kbps
upstream.

It depends on what BT do with the new product but upstream of up to
768Kbps has been mentioned depending on exchange distance.

Good question - I should really have given you what I want rather than a
partial solution.

I currently have a 1 Mb ADSL line (hopefully being upgraded by Demon to
2 shortly) and download about 2 GB a night (clients backups)

I would like both increase capacity and provide redundancy.

I presume the FTP server in the server would support both incoming
lines.

As cream on the cake it would be nice if other PCs on the network could
access both/either lines, but not really necessary.

Load balancing is also not necessary.

I've done this with two routers (for a while there was a third on ISDN
too... line rental for the HH when they forced BT Together Option 1 on
everyone was he time when I cancelled that, to save 300 a year).

Who mentioned balancing the load ? That might not be needed. Yes, it
is certainly quite easy to do, depends a lot on what one wants though!

Unsuitable for heavy downloaders, but fine for video/audio streaming.
