I'm looking for direction on how to install a ADD ON MODULE for a DSC(AOM). I have a Office Serv 7200. This add on module will give an employee the ability such as a receptionist to see all the extensions that are in use. I know the receptionist will need two RJ11 keystone jacks in the wall (one for the phone and one for the add on module). I know where there extension punches down on the 66 block. Where can I cross connect there extension to for the add on module? Is there a port on the 7200 that I connect to on the 66 block then cross connect the extension to where that terminates? Also, what MMC modules should I be looking at to configure this in the the Samsung management software?
