INSTALLING YOUR VOICE TERMINAL
IMPORTANT: For a fuller description of installing the 8400-Series voice terminals
and procedures on administering these sets and programming such options as
enabling/disabling the speakerphone or one-way speaker, enabling/disabling the Mute
function, selecting ringing preference, or selecting handset and speaker volume
control, see the 8400-Series Voice Terminals Instructions for Installation, Switch
Administration, and Programming the Options, 555-015-725. (This document can be
ordered from the Lucent Technologies BCS Publications Center at 1 800 457-1235.)
Distance Limitations
In 4-wire operation, the voice terminal must be within 5,000 feet of the PBX using
22-gauge or 24-gauge wire, and within 4,000 feet of the PBX using
26-gauge wire.
In 2-wire operation, the voice terminal must be within 5,500 feet of the PBX using
22-gauge wire, within 3,500 feet of the PBX using 24-gauge wire, and within 2,200
feet of the PBX using 26-gauge wire.
Auxiliary Power
In both a 4-wire or 2-wire configuration, most 8400-Series voice terminals are
phantom powered from the PBX. However, you will need auxiliary power in the
following instances:
• If you are using an 8411 or 8434DX voice terminal (These sets require auxiliary
power.)
• If you have an 801A Expansion Module (used ONLY with the 8434DX voice
terminal connected to a DEFINITY
®
Communications System G3V3.3 or later
switch)
• If there is an attached adjunct equipment, such as an S201A Speakerphone
