WATS or FX trunks) without dialing a code. The Pool button is used to make
only outside calls. To make a call, the user dials the area code and telephone
number and does not need to dial the ARS code or dial-out code for the
trunk pool. A Pool button can appear on a maximum of 64 stations.
Loudspeaker Page button— used to make announcements over an optional
loudspeaker paging system. To make a loudspeaker announcement, the
user simply selects the Loudspeaker Page button, then speaks into the
handset. The user does not need to dial the extension number for the
loudspeaker paging system.
The system is factory set to assign certain kinds of line buttons depending on
the type of equipment. For non-operator multiline telephones, the system
assigns a System Access Ring, System Access Voice, and System
Originate Only button. See Figures 3-3 and 3-4.
