Uses an amplifier connected to an analog extension port via a 600ohm isolating transformer. Some amplifiers include an integral transformer. Avaya/Lucent branded amplifiers are designed for connection to special paging output ports not provided on systems. They are not suitable for supporting mixed paging.

The transformer and amplifier must be connected when the system is restarted.

If background music is required between pages, the amplifier must support a separate background music connection and VOX switching.

The analog extension port is set as a Paging Speaker in the system configuration (Extn | Analog | Equipment Classification).

Short code/programmable button: Use DialPaging.
