Ot GENERAL-
01 .OO Summary Description
01.01
Strata
S is an electronic key tele-
phone system with many standard features utiliz-
ing stored program control, custom LSI circuitry,
solid-state space division switching, and reduced
station cabling. Served by a key service unit
(MKSU) housed in a single cabinet, the system has
a capacity of three central office/PBX lines, one
intercom line, and eight station lines.
01.02 Strata S utilizes specially designed
electronic key telephones (EKTs). Each EKT is con-
nected to the system via industry-standard 2-pair
cabling, and is equipped with a push-button dial
pad. Solid-state electronics within the MKSU
translate signals from the station dial pad into
either DTMF or rotary dial signals, as required by
the central off ice.
01.03 Strata S is electrically compatible
with the public telephone network and is also
designed to function in a “behind PBX” envi-
ronment.
01.04 Maintenance procedures are based on
quickly locating and replacing defective sub-assem-
blies, keeping service disruption to a minimum.
02 PHYSICAL DESCRIPTIONS
02.00 Key Service Unit
02.01 Designed for wall mounting, the
Strata S MKSU is housed in a single plastic
cabinet (Figure 1) with the following dimensions:

ACOU: 9.4 x 6.3 inches (239 x 160 mm)
02.04 The MMAU PCB is secured to the cabinet
base (Figure 3). The ACOU is attached to the
MMAU with four screws. and is connected to it via
four 1O-pin connectors.

(EKTs) may be used in the
Strata
system. The
standard EKT (Figure 4), known as a lo-key “S”
EKT, is equipped with three permanently dedi-
cated keys and ten line/feature keys. All three
optional EKTs are full speakerphones and are
and is equipped with 13 line and feature keys in
addition to its push-button dial pad. Three of the

02.13 All three optional EKTs have the same
external dimensions: answerback and full speakerphone capability.
Height: 4.0 inches (102 mm)
Width: 8.8 inches (224 mm)
Depth: 9.1 inches (230 mm)
02.16 The optional 1O-key BLF EKT provides the
same features as those listed in Paragraph 02.15,
plus an LED indication of which stations are in
use.
Each is equipped with either 14 or 24 line/feature
keys in addition to a push-button dial pad. Again,
three of the keysare utilized for CO/PBX lines, one
for intercom access, and the remaining keys are
used for feature operation.
02.14 System software assignments permit some
variation to the feature keys on all four EKTs.
02.17 The optional 20-key EKT provides the
same features as those listed in Paragraph 02.15,
and has ten additional feature keys. That is, three
CO/PBX keys, one intercom key, and 16 feature
keys that may be used as automatic dialing keys,
direct station selection (DSS) keys, etc. Three dif-
ferent combinations of feature keys may be
selected via programming.
02.15. The optional 1O-key EKT provides the 02.18 All EKTs feature modular handset cords
same programmable feature keys as the standard and are connected to the system via four-con-
EKT, plus a microphone control key, handsfree ductor modular line cords.

03.01 The electrical characteristics of the sys-
tern are detailed in Table A.
03.02 The MKSU operates from an external 24
VDC power supply.
03.03 Loss of AC power will cause operational
failure of the system. System memory, however, is
protected from loss due to power failure with a
memory back-up battery. Full system reserve
power is available as an option.

M.. 05 SYSTEii OPERATIO’N
05.01 The system (Figure 8) consists of an
MKSU, power supply and up to eight EKTs. All
connections between the MKSU and the EKTs are
made via a customer-provided main distribution
frame (MDF). Using modular line cords, the CO
lines are then connected between the ACOU and
locally-supplied RJ-25C jacks. An external tuner
or an AMOU PCB is required if the music-on-hold
feature is to be utilized.
