> MT is a router, why bridge! :) Ease of central management. We don't have a good way to track all the IPs and confgiurations that get assigned to the MT. Most of our MT CPEs terminate in Tenant buildings with Multiple subs. Traffic is easy to seperate, when VLANs can get past through end to end. In our central cell site management system, we built a system to record, test, provision, and de-provision IP configurations. To do it with MT routing on the middle devices, it means writing/finding text docs archived somewhere, that documented the more complex less consistent configurations. These are reasons that I prefer simple bridge backhaul radios, for my network. I don't want them to be overly intelligent.
>From a technical perspective, yeah, it would be better to route. But I don't care about the technical details as that is not tied directly to profitabilty, but my time saving to manage it definately translates to my profitabilty. However, there are many places that a NStreme MT w/ routing can be inserted into a network, where it does NOT create additional management headaches. Sometimes, even easier to manage. And many WISPs dont own a central management router system at their cell sites. The MT itself becomes their way to manage their configurations. Those are all great places to use MT w/ routing. I will also be the first to admit that WDS is a dog, performance wise. But MT solved that, by making faster processor boards, and inexpensive.
