Hello<br />
What kind of hardware do you have? How is your network topology and routing points?<br />
<br />
If you do not have any routing points you must have equipment that support HSRP or VRRP (two devices use one virtual ip) to accomplish the task you described

To be honest I think you can give a try with Cisco 1800 series with dual DSL to provide redundancy.<br />
By default none of the models have dual DSL, but you can purchase additional DSL module to have dual DSL connectivity on that device.<br />

Network analysis is the process of identifying and remediating the processes and systems within a network, including performance, connectivity and security. The process is performed through the use of tools developed for monitoring and analyzing network activity. Network problems that involve finding an optimal way of doing something are studied under the name combinatorial optimization. Examples include network flow, shortest path problem, transport problem, transshipment problem, location problem, matching problem, assignment problem, packing problem, routing problem, Critical Path Analysis and PERT (Program Evaluation & Review Technique).

Network Analysis

Networking is the process of connecting computing devices, peripherals and terminals together through a system that uses wiring, cabling or radio waves that enable their users to communicate, share information and interact over distances. Often associated are issues regarding operating systems, hardware and equipment, cloud and virtual networking, protocols, architecture, storage and management.
