3 REFERENCE DOCUMENTATION
3.00 The STRATA DK systems are supported by
the following complement of reference documen-
tation, in addition to the installation section:
3.10 General Description: An overview of the
three STRATA DK systems and their features.
3.20 Programming: Provides detailed step-by-
step instructions on how to program each system.
Also provides tables, called System Record Sheets,
on which all programming and configuration infor-
mation can be recorded.
3.30 User Guides: Provide step-by-step instruc-
tions on how to operate stations connected to the
STRATA DK system. There are separate user
guides for the digital telephone, electronic tele-
phone, standard telephone, digital telephone Liq-
uid Crystal Display (LCD), electronic telephone
LCD, direct station selection console, and data
interface unit.

bleshooting and diagnostic information presented
in flowchart form.
3.50 Remote Maintenance and Administration:
Programming and maintenance procedures spe-
cially adapted for remote maintenance and ad-
ministration terminal use. Detailed, step-by-step
instructions are provided, complete with the termi-
nal responses.
NOTE:
These procedures also apply when using a
local ASCII terminal connected directly to the
DK system.
4 SYSTEM MNEMONICS/TERMS
4.01 Mnemonics are used to identify the system’s
hardware, operation, and features. The following
alphabetical listing describes the mnemonics used
in this manual.
BPS: Bits Per Second—Unit of measure that re-
fers to the transmission speed (baud rate) of
electronic signals. It is used when describing
data interface unit and modem operation.
CO: Central Office—The facility which houses
switching equipment that provides telephone
service (CO lines, E & M TIE lines, Centrex
lines, etc.) for the immediate geographical area.
CO Line: A term used to define the STRATA DK
hardware circuit that connects to the central
office network line pair. Each CO line and TIE
line circuit is assigned a CO line number in
system software.
CODECs: Coder/Decoder—Semiconductors that
allow the system to process analog-to-digital
and digital-to-analog conversions.
CRCU-4: An optional upgrade to the system’s
controller printed circuit board (PCTU or PCTUS)
that provides a 4-circuit Dual-tone Multi-fre-
quency (DTMF) receiver for system Direct In-
