Analog Extension Features

Up to 30 analog extensions can be programmed based on the number of 303 Cards installed in the system. The ports can be defined as:

Phone

Designed to provide for standard 2500-type phones.

Common ringer

Connected via a tip-and-ring pair; will apply ring voltage whenever a line rings in night mode.

Fax

If the auto attendant detects a fax tone, it will automatically forward the tone to the analog port programmed as "FAX."

Modem

Incoming calls for a modem can be manually transferred to the modem extension; also, the modem can automatically generate outbound calls.

Door phone

A telephone connected to this port will automatically dial the programmed ring-down extension number whenever the set is taken off-hook.
