Modeling Explicit Feeders

To allow the NMT to model explicit feeders, enter the following information about the feeder site into the Site table:

•link connecting the hub and feeder in the Link table

•connection interfaces in the Traffic tables (as if the node were not a feeder). For explicit feeders, connection endpoints are the feeder nodes.

IGX and IPX nodes can be modeled as either hub or feeder nodes. The MGX 8820 can only be modeled as a feeder. Beginning with NMT 9.2, the MGX 8820 can be an explicit feeder as well as an implicit feeder.

The MGX 8850 is also modeled in NMT 9.2. As a feeder node, the MGX connects to the BPX. If modeled as a feeder, The MGX 8850 node must be explicit.
