A designated group of up to 16 master stations or telephones can be called from any substation, which is
answered from any called master station (telephone).

First, one of master stations (telephones) in a group must be programmed as a representative station, and the
rest as member stations. Then, a calling substation must be programmed to call the representative station.

(telephones) in the designated group.
