Bschear,
Generally if you have a Bogen system a TAMB is the way to go. You can use either a Cisco FXO or FXS port to access it. The Bogen manuals are quite good at explaining how to set it up.
I'm not a paging guru but have done some over the years, and used the TAMB with other manufacturers as well.
I don't know of any paging documentation other than what is available from the paging equipment manufacturers (which I normally research by model # on the web when I need to deal with one), perhaps someone else from the list knows more.
HTH,
Art
