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
G3V3.3 or later switch)
If there is an attached adjunct equipment, such as an S201A
Speakerphone
