automatic configuration is possible. Notice for IPv4 standalone home routers, most routers still need a manual configuration to choose if the home has a DSL or cable broadband access.
Here, both types of access is usually through a modem, not a router. The modem provides the customer with ethernet. If the customer chooses to install a standalone router chained off of the modem, there's really no additional choice to be made. The only choice is whether to go with a cable or DSL access provider. Once that choice is made, the modem type is already determined.
Also, in your DSL deployment, do you have an embedded router in a DSL modem or is the router a standalone router? An embedded router has lot more automatic configuration because the L2 of the device can communicate internally to the embedded CPE Router.
That depends on the customer. In the embedded case, conceptually it's simplest to think of the device as having a virtual ethernet connection between built-in modem and built-in router (when the customer chooses to use an embedded router device they normally lose the option to hang additional devices off the WAN link). I'm not aware of any consumer embedded-router/modem being used here where the router functionality behaves significantly differently than that of a standalone-router. The communication between the L2 device and the router really boils down to whether the WAN connection is up or down and that's really independent of whether an embedded router or standalone router is being used.
