Are you trying using two WIC-1SHDSL cards? I do think this is only
possible with the newer 4-wire enabled WIC-1SHDSL-V2 card. Btw, I don't
think it isn't possible to bond two of those cards either.

The bonding of G.SHDSL wires is done using IMA, and there is probably no way to
run IMA across different WIC's.

Using the V2 card it's straightforward, just enable the '4-wire mode'
(line-mode [2-wire | 4-wire | auto]).  There will be only one
ATM-interface, so you can reuse the rest of the config from a 2-wire
box.

There is a good config guide on CCO, just search for 'wic-1shdsl-v2' and
look for the documentation road-map -> Software Configuration.
