2 TELEPHONE/SYSTEM CONNECTION

2.00 General
2.01 This section describes the wiring required to
connect telephones to the system. Before install-
ing any telephone wiring, read the following warn-
ing and caution notes:
WARNING!
1. Never install the telephone wiring dur-
ing a lightning storm.
2. Never install the telephone jacks in
wet locations, unless the jack is spe-
cifically designed for wet locations.
3. Never touch uninsulated telephone
wires or terminals unless the telephone
line has been disconnected at the net-
work interface.
4. Use caution when installing or modify-
ing telephone lines.
5. If telephone wiring exits the building,
external secondary protection is re-
quired. See Section 400-096-209.
CAUTION!
When installing the station cable, do not
run parallel to and within three feet of an
AC power line. AC power lines should be
crossed at right (90
ticular, avoid running station wire pairs
near devices that generate electrical noise,
such as neon or fluorescent light fixtures.
2.10 Connecting Digital Telephones to the
System
2.11 The following provides information on how to
connect digital telephones to the system.
NOTE:
Before proceeding, see warning and caution
notes in Paragraph 2.00.
2.12 Digital telephones connect to the Digital Tele-
phone Interface Unit (PDKU) via the main distribu-
tion frame (MDF) with standard twisted-pair jack-
eted telephone cable. Single-pair wiring is suffi-
cient in most cases for digital telephones to oper-
ate effectively at up to 1000 feet from the key
service unit, if using 24 AWG cable. But digital
telephones that are equipped with Integrated Data
Interface Units should have two-pair (or external
power) to function effectively at this distance. This
also applies to digital telephones that are sup-
ported by systems that must operate with battery
reserve power—see Wiring Diagrams, Section
400-096-209, for loop limits.
