How to set up Private nodes Radioless nodes

Is there any info on how to setup a private node and Hub? I want to do this on AREDN mesh node. First I guess I need to set up a Hub. How do you do that? Second, How do you set up the nodes that are connected to it. My private nodes are Radioless… I just can’t find any step by step from beginning to end anywhere. Any help would be greatly appreciated.

Radio-less node is the same as mentioned in the wiki, only your channel driver would be dahdi and not radio/simpleUSB

I should have added that it is also possible to use USRP as a channel driver for a radio-less node.
DAHDI is the universal standard that allows full iax interoperability.
