if Ń…DSL operates in transparent L2 bridge mode and ISP have decent termination equipment, you can have 802.3ad link aggregation on top of two links. some xDSL modems have a feature, when Ethernet link state follows DSL link state. I remember having setup like this to trunk two ProCurve switches over two DSL lines.
