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.

are field installed. The AEPU is secured to the 
and either 10 or 20 feature keys. Because of the 
MMAU with two screws and is connected to it via

02.11 Four diierent Electronic Key Telephones 
(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 
keys are utilized for central office/PBX lines, one 
for intercom access, and the remaining keys for 
feature operation.

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 1 O-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 1 O-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.

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.
