Backbone Topology

Routers connect device channels to a common backbone channel. Typically, the

backbone is a high-speed channel, such as high-speed twisted pair, TP/XF-1250, or

LONWORKS/IP. Each device channel can have either a free or bus topology. It is not

necessary that each channel have the same topology. The guidelines for bus and

free topologies (that is, termination requirements and wiring length) must be

applied to each individual channel.
