It's been awhile since I set up talk back paging. As I remember, the output on the Valcom talkback unit has to be connected to a line port on the KSU. Anyone have a guide or more info on this?
Anyone have a diagram of the connections to make this work? This was already installed where I did a BCM install and there was no documentation for it. The Valcom unit has a 25-pair cable connected to a 66 block but all the wires were disconnected.
