Backhaul: A verb. Often connoting: "Getting there over a much longer, yet more economically efficient, route." One would think that this could only be made possible through a number of artificially contrived constructs, such as disparate and skewed tariffs, meaning the lumpiness that exists between inter- and intra- state models.
But other situations exist that make backhauling necessary, or at least more attractive than going the way of the crow, such as those situations where it's cheaper to lease from someone else, even though they are out of the way, as opposed to rolling your own.
In an earlier message of mine on the LMT this afternoon ...

... I made a reference to the use of fiber systems for backhauling traffic on cellular/pcs networks.
I've come across this term "backhaul" in a growing number of contexts, recently, so I thought I'd check out a few glossaries and see if there was any a common theme between them. What follows demonstrates a fairly consistent theme, although you can easily tell that each author's definition, by their use of the term, is directly related to their respective market niche. Even in some of these glossaries where, presumably, they give the appearance of being "generic" in nature, the biases of the authors come shining through, just the same. Bigotry has a hard time hiding, it seems ;)

Backhaul - Backhaul is a high capacity inland circuit. It represents the connection between a cable landing station and an operators existing domestic infrastructure. (fac: brought to you by the same OFTEL as in the preceding entry.)

Backhaul - In a Wide Area Network (WAN), communications between a WAN port on a LAN and either a subscriber port on a service provider's network or another WAN port on a second LAN. Often, the backhaul links the user facilities to the backbone. (fac: ??)

Backhaul – the practice of bringing demand to a service rather than bringing service to the location where it is required. A term used to describe the charges resulting from a circuit required to connect a location without requested service to a site where the service is offered. Backhauling adds considerable expense to network connections because it commonly uses circuits that are priced by distance.

backhauling: Ref: 24 - carrying traffic beyond its destination to another location before switching it back. Carriers typically backhaul when it is less expensive than going directly. (fac: this is often the case when it is far less expensive to go a thousand miles out of the way on Interstate tariffs, as opposed to travelling three hundred miles on an intrastate one. Some “switchless” voice resellers use this tactic to support in-state discounted voice, even though their lines go out of state. This approach is also demonstrated in the entry following this one)

Backhaul -Back haul is a verb. A communications channel is back hauling when it takes traffic beyond its destination and back. There are many reasons it might do this. The first is that it may be cheaper to go that route instead of going directly because you might have a private line working. You might, for example, have a full-time private line from New York to Dallas. You might find it cheaper to reach Nashville by going to Dallas first, then dialing back to Nashville.
