also appear in this chapter.
1 .I 0 Types of Telephones
1.11 The STRATA DK8 and DK16 systems can
support the following telephones.
Digital Telephones: Installation instructions for
digital telephones in this chapter and elsewhere
in this manual apply only to the Toshiba 2000-
and 1 OOO-series Digital Telephones. The 2000-
series Digital Telephones consist of four mod-
els: the DKT201 O-H, the DKT2010-SD, the
DKT2020-S, and the DKT2020-SD. There are
two 1 OOO-series Digital Telephone models, the
DKT1020-H and the DKT1020SD.
Electronic Telephones: (DK16 only) The elec-
tronic telephone instructions here apply to the
Toshiba 6500-series Electronic Telephones,
although there are other electronic telephones
(the 2000-, 3000-, 6000-, and 6500-series) that
are compatible with the STRATA DK16. The
6500~series electronic telephones consist of
four models: the EKT6510-H, the EKT6510-S,
the EKT6520-H, and the EKT6520SD.
Standard Telephones: 500- and 2500-type
standard telephones apply whenever standard
telephones are mentioned in this manual.

INSTALLATION-STATION APPARATUS
SECTION 100-816-206
MARCH 1993
WARNING!
Never install the telephone wiring dur-
ing a lightning storm.
Never install the telephone jacks in
wet locations, unless the jack is spe-
cifically designed for wet locations.
Never touch uninsulated telephone
wires or terminals unless the telephone
line has been disconnected at the net-
work interface.
Use caution when installing or modify-
ing telephone lines.
If telephone, DSS console, Door phone
control box, or Door phone wiring ex-
its the building, external secondary
protection is required. See Section 1 OO-
816-208.
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”) angles only. In par-
ticular, avoid running station wire pairs
near devices thatgenerate electricalnoise,
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 DK8 or DK16
system.
NOTE:
Before proceeding, see warning and caution
notes in Paragraph 2.01.
2.12 Digital telephones connect to the digital tele-
phone ports via the main distribution frame (MDF)
with standard twisted-pairjacketed telephone cable.
Single-pair wiring is sufficient in most cases for
digital telephones to operate 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 Inter-face Units or
ADMs should have two-pair (or external power) to
function effectively at this distance. This also ap-
plies to digital telephones that are supported by
systems that must operate with battery reserve
power-see Wiring Diagrams, Section l OO-816-
208, for loop limits (see Table 8-D).
