Last month we ordered a 2Mbit SHDSL Internet connection. However we have just been informed that we are too far from the telephone exchange to use SHDSL so now we are looking at other solutions.
I am thinking about the possibility of bonding together a few 512k up/down ADSL connections to achieve 1Mbit+ Internet Connection. We are also wanting to include QoS on the router so that any H.323 (video conferencing) traffic will be given priority on one of the ADSL connections since we have just upgraded our GENESIS equipment to include support for IP, but we are too slow at the moment to use it.
We are also hosting an Internet for a few bases around Australia, so they would definitely appreciate an increase in bandwidth.
Any advise that anyone here can offer would be greatly appreciated.
Thanks.
Bonded ADSL
Hi Bill, Nice to see all the work you guys have done!
I did a little research on bonded DSL here and found that it was very hard to get anyone from the telco that even knows what you are talking about. They just want to sell standard packages.
As I understand you need a setup both at your location and at the telco exchange to aggregate the bonding.
I have the luxury of a theoretical 24 Mb/s down and 1Mb/s upstream. Reality seems I get 15 down and 1 up. Not bad eh!
Another issue for GENESIS is having your bandwidth either dedicated or on a lightly used 'pool'. Most DSL providers pool up to 50 domestic customers on the same bandwidth. Corporate is a bit better - about 5 users here.
There are other issues for GENESIS and maybe I should open a GENESIS folder here.
We just received the Sony PCS-G70 here in Dalarna - a fantastic buy on EBay!! Praise God!

Another Option for Faster ADSL
Thanks for the feedback Mike.
I was actually wrong in my description of what I wanted. It wasn't actually bonded ADSL, I was more just looking for a router that would allow multiple 512k ADSL connections to service the network. I want good QoS so that when we do GENESIS I can dedicate one of the 512k connections just to the H.323 signal. I reckon that would probably work pretty well for us.
I found this product that looks like it might do what I want. You need your own modems for it, but that's a good thing since then we can actually run multiple ADSL2+ connections if we get really keen.
Here is the link to the product:
DrayTek Vigor 3300V.
I reckon it would work pretty well from what I can read...
One of the obvious downsides with this instead of proper bonded ADSL is that we would be limited to 512k (or maximum single connection speed) per GENESIS connection (or any protocal for that matter). But if we get 512k that would probably still work pretty well for GENESIS.

Bill, what it sounds like you're after is a load balancing firewall. These can combine two adsl channels, doubling your adsl bandwidth. If you don't yet have a solution, I suggest you take a look at a Zyxel 35 firewall. http://www.zyxel.com/product/model.php?indexcate=1082973192&indexFlagvalue=1085450410
Balancing is NOT aggregation
Hi Philip
A small correction to your comment. The Zywall type option is great to balance the load between two DSL connections. It is not quite the same as doubling your bandwidth - in as much as no application can get more than the speed of one of the ADSL links.
see
http://kb.linuxvirtualserver.org/wiki/DSL_Load_Balancing
for an explanation.
You will get more to play with, but no application will get more than the upload of one of the links, and that is a challange for things like GENESIS in Latvia who are limited to 128k upstream for each link.
