To play devil's advocate to Chris' post,
TCP/IP is a viable monitoring option, however as he alluded to, which I will clarify, in order to be reliable and bulletproof, you're looking at a network within the realm of business/enterprise level service (restoration within X time) and hardware. The CS's already have the wiring integrity and redundancy as well as contracts for service restoration/re-routing in the event of catastrophic events, all of which is covered within their UL listing, which most people don't start investigating or care about (really dry reading and hard to find for most service providers).
In addition to that, you need to have a CS that is well versed in TCP/IP monitoring and how to set it up as well as respond to it. The fact of the matter is, from what I'm reading, a lot of the CS's that deal with end users don't know how to respond or act with the system's supervisiory settings, let alone act appropriately when the systems fail to perform. This is further compounded when you install this hardware on a residential, end-user grade network and components.
