How to combine 2 adsl connections

| Hi,
Currently i am trying to combine 2 adsl lines for more bandwidth. The 2 adsl
modems (non-cisco but seem very configurable..) are in different locations
in the building so from where the routers are installed i have patched them
into 1900 series switches which are connected by fibre. From one of the
switches i have an ethernet connection to my pix which goes back to my 5509.
The problem is that only one of the adsl lines is being used. How could i
combine these connections given my circumstances?
Thanks for your time
Stephen Hughes

| I think you're going to find that this is not possible. Even if they are from the same ISP, providers are usually not open to configuring the proper routing for their non "dedicated" services. This usually requires the leasing of a DS1 or DS3 line.
If they are from different ISPs, you would have to run BGP on a router behind these connections in order to leverage them, but again, your provider is probably not going to support it. And running BGP isn't actually going to "bond" these connections in the first place.
If having the aggregate bandwidth is a business requirement, I would suggest a dedicated service from a reputable ISP. | |

| DSL uses PPPoE which allows for multilinking to combine multiple physical lines but your ISP probably doesn't support multilink PPP. | |
