●Dialing out or in. When a voice terminal goes off- hook, it signals the control unit to make a connection through a network switch to an available or requested outside line. When the path is established, the voice terminal receives a dial tone. The control unit will select a path in its multiplexing scheme to make the connection. A call coming into the will

activate the ring indicator in the control unit and generate control signals to alert the voice terminal.

●Intercom call. Intercom calls can be made from one voice terminal to-any other voice terminal connected to the control unit. Dialing the intercom number of another voice terminal will cause the control unit to establish a voice path between both voice terminals.

Loudspeaker paging. The system interfaces with auxiliary equipment such as a power amplifier and loudspeaker for single or multiple zone external paging.

Programming. In programming mode, instructions keyed into a voice terminal are stored in the control unit’s memory; the voice terminal itself has no memory. When a particular feature is requested by a voice terminal, the control unit examines its memory to determine the features for that station.

For an analog voice terminal, you enter and exit

programming mode by using the T/P switch. For a digital voice terminal, which doesn’t have a T/P switch, you must use a dial code to enter and exit programming mode. For a basic voice terminal, the administrator must program any feature changes.

●Telephone paging. The MERLIN II system allows paging over voice terminal speakers. The Group Page feature allows paging to a maximum of 10 voice terminals. The Page All feature allows paging to all voice terminals in the system.
