Also known as customer rearrangement. A PBX administrative feature that allows the end user to accomplish set relocations without technical assistance. The user simply takes the phone from one location to another, plugs the set into the wall jack and dials a relocation code. The set identifies itself to the PBX, which changes the station port assignment and reassociates the station number and all assigned features to the new port. The feature considerably simplifies Move, Add, and Change (MAC) activity and lowers the associated costs.
