Integrate DSL via a Cisco router and a WSC card?

My company would like to test DSL as a temporary BACKUP for our WAN partial T1 connection to branches and as added bandwidth. We presently use ISDN. Our Network people are busy working on an emergency recovery plan and don't have time to help me. I am a training person, and want the extra bandwidth to deliver on-line training. Since I need this to happen sooner than later, I am looking into the details of pricing. But, I am really clueless in understanding what we need. Sadly, the DSL providers may be even more clueless <grin>.

Basically, we want to install DSL in our branches. Then, connect the DSL service to the network via a Cisco router (6160, I believe). As I understand it, the analog to digital conversion is done by a DSL modem. We then have to connect the modem to the router. Unlike home service, this just isn’t a plug in to a hub since we are integrating more than one service. One solution mentioned is using a WSC (?) card in the router but no one has had the time to think this one out. I think the plan is to direct specific activities via the T1 or DSL depending on the link. For example, links to the training Intranet site would be directed to DSL. More critical business traffic would go via the partial T1.

My question:
Are there several ways to accomplish this goal? The network people will understand the solution so I need just enough detail to clearly define each approach and which is the preferred method. The critical part of this answer is the equipment list for each so I can get pricing. I think all I would need is a WSC card and the DSL service (and modem). But, there may be an approach that would require additional equipment. Once I can present methodologies and associated prices, I can probably get us moving on a decision. I’ll try to provide clarification if you need it. Thanks.
