Trunking ASDL2+ WAN Links

So, I'm making a project for myself. I want to see how many ADSL2+ links I could trunk together in aggregate. My question is, what's the best way to do this?

First idea was, get loops installed, get stack of DSL modems, plug the LAN cables into ports on a Cisco switch and trunk them.

Second idea was get a used Cisco 3508G XL switch and a bunch of ADSL2+ GBICs and go to town.

Thoughts?
 
ADSL2 GBICs? There's no such thing.

Aggregating ADSL2 links is typically done via MLPPP (though it could be done with inverse multiplexing if the links are ATM-based) which requires support with both the provider and the modems (or whatever is handling PPP).

What you are thinking of doing won't work and doesn't even make sense. Ethernet link aggregation requires ethernet services, not ADSL services.

Also, 3500XL switches are garbage.

To answer your main question, most platforms have a limit of 8 members in an MLPPP bundle.
