I have a external RAD at a location, I am trying to figure out what line to set the RAD to answer because we have a POTS line installed just for remotes. A site survey done a while ago says this number is line 11 on the demark, does that translate in to line 63 or 67 on my MICS? Also, when I go in to RAD programing remotely through Norstar Manager the KSU line numbers only go up to 8? Why? Any help would be appreciated, thank.
