FCC REGISTRATION TOSHIBA PUBLICATIONS 
SECTION 300-020-000 
JULY 1986 
The Strata XII, & XX,electronic key tel- 
ephone systems are registered in accordance with 
the provisions of Part 68 of the Federal Communi- 
cations Commission’s Rules and Regulations. 
FCC REQUIREMENTS 
Means of Connection 
The Federal Communications Commission (FCC) 
has established rules which permit the Strata 
X/I,&XX,electronic key telephone systems to 
be connected directly to the telephone network. A 
jack is provided locally-connectors for this type of 
customer-provided equipment will not be provided 
_ on party lines or coin lines. 
Incidence of Harm 
If Strata is malfunctioning, it may also be 
disrupting the telephone network. The system 
should be disconnected until the problem can be 
determined and repaired. If this is not done, the 
telephone company may temporarily disconnect 
service. 
Telephone Network Compatibility 
The telephone company may make changes in 
its technical operations and procedures. If such 
changes affect the compatibility or use of changes 
affect the compatibility or use of a 
Strata sys- 
tem, the telephone company is required to give 
adequate notice of changes. 
Notification of Telephone Company 
Before connecting a Strata system to the 
telephone network, the telephone company must 
be provided with the following: 
A. Your telephone number 
B. The FCC registration number (BF 287N-71954- 
KF-E) 
C. The ringer equivalence number (0.5 B) 
D. The USOC jack required (RJ-25C or RJ-11 C) 
Items B, C, and D are also indicated on the equip- 
ment label. 
You must notify the telephone company upon 
final disconnection of your equipment. 
RADIO FREQUENCY INTERFERENCE 
Warning:-This equipment generates, uses, and 
can radiate radio frequency energy and if not 
installed and used in accordance with the instruc- 
tions manual, may cause interference to radio 
communications. It has been type tested and 
found to comply with the limits for a Class A com- 
puting device pursuant to Subpart J of Part 15 of 
FCC Rules, which are designed to provide reason- 
able protection against such interference when 
operated in a commercial environment. Operation 
of this equipment in a residential area is likely to 
cause interference; in which case, the user at his 
own expense will be required to take whatever 
measures may be required to correct the inter 
ference.

							01 GENERAL 
01 .OO Summary Description 
01.01 Strata Xl/f= & XX& 
are elec- 
tronic key telephone systems that provide a 
wide range of sophisticated, user-friendly fea- 
tures. These systems offer stored-program 
control, custom LSI circuitry, solid-state space 
division switching and reduced station cabling. 
Both systems are very similar and use the 
same printed circuit boards for station lines, 
CO lines and control. The difference is in the 
capacity of the two key service units (HKSUsj 
and their power supplies. 
Strata Xi!.. has 
a maximum of 12 CO lines and 32 stations, 
while 
Strata XX& will accommodate up to 
21 CO fines with a maximum of 56 stations. 
Both systems are housed in single cabinets. 
4 ICM paths on XII up to 6 paths on XX 
01.02 The Strata systems utilize spe- 
cially designed Electronic Key Telephones 
(EKTs). Each EKT is connected to the system 
via industry-standard 2-pair cabling, and is 
equipped with a push-button dial pad. Solid- 
state electronics within the HKSU translate 
signals from the station dial pad into either 
DTMF or rotary dial signals, as required by the 
central office. 
01.03 80th systems are electrically compati- 
ble with the public telephone network and are 
also designed to function in a “behind PBX” or 
Centrex environment. 
01.04 Maintenance procedures are based on 
9 uickly locating and replacing defective 
plug-in

mum. 
02 PHYSICAL DESCRIPTIONS 
02.00 Key Service Units 
02.01 Each Strata HKSU consists of a 
single metal cabinet (Figures 1 and 2) with the 
following dimensions: 
Strata XII= 
Height: 18.8” (478 mm) 
Width: 14.4” (366 mm) 
Depth: 12.5” (318 mm) 
Weight: 44 Ibs. (20 kg) 
Strata XX& 
Height: 26.5” (673 mm) 
Width: 14.5” (368 mm) 
Depth: 12.3” (312 mm) 
Weight: 61 Ibs. (28 kg) 
FIGURE 2 - Strata XX~ HKSU 
Both cabinets are designed for table-top or 
wall mounting. 
02.02 The Strata X& HKSU (Figure 3) 
contains two shelves with spaces to accommo- 
date up to 11 printed circuit boards (PCBs) and 
one power supply (HPSU 8120). Two additional 
PCB slots are reserved for future use.

loo-pin connector. All external .- 
HKSU connections are made on 
the front panels of the various 
PCBs via cables with industry- 
standard connectors. 
02.10 Electronic Key Tele- 
phones 
02.11 Six different Electronic 
Key Telephones (EKTs) may be 
used in both systems. The lo-key 
EKT (Figure 5) is available as a 
speakerphone or with handsfree 
answerback (HFU) only. The two 
models, identical in appearance, 
are equipped with four perma- 
nently dedicated keys and 10 
line/feature keys. The HFU model 
may be answered handsfree on 
intercom calls only. The lo-key 
BLF EKT with speakerphone (Fig- 
ure 6) is similar in appearance to 
the lo-key, but with a Busy Lamp 
Field (BLF). 
02.12 Three additional EKTs, 
similar in appearance to the lo- 
key, with 10 additional flexible 
keys, are also available. The 20- 
key EKT (Figure 7) is available as 
a speakerphone or handsfree an- 
swerback only. The two models, 
identical in appearance, are 
equipped with four permanently 
dedicated keys and 20 line/fea- 
ture keys. A 20-key Liquid Crystal 
Display (LCD) EKT with speaker- 
phone (Figure 8), which has a 
32character alphanumeric .dis- 
plav, is also available.  02.03 The Strata XX= HKSU (Figure 4) 
contains three shelves with spaces to accom- ’ . 
modate up to 18 PCBs and one power supply 02.13 All 
(HPSU 9120). Three additional PCB slots are 
reserved for future use. t 
NOTE: 
Several Strata PCBs utilize plug-in 
sub-assemblies that are mounted directly 
on the host PCB. These sub-assemblies 
may or may not be required for a particu- 
lar system - see System Configuration 
for complete details. 
02.04 Each PCB measures 8.7 x 7.1” (220 x 
180 mm) and is equipped with either a 64- or EKTs have the same dimensions: 
ieight: 3.63” (92.2 mm) 
Width: 7.0” (178 mm) 
Depth: 9.0” (229 mm) 
02.14 Housed in an impact-resistant, off- 
white plastic case, each EKT comes with a 
brown faceplate (with wine, black or blue face- 
plates available as options). Each is equipped 
with four permanently dedicated feature keys 
and either 10 or 20 line/feature keys in addi- 
tion to a push-button dial pad. Up to 9 or 19 
(lo- or 20-key, respectively) keys are utilized ’ ”

for CO/PBX lines and one for 
intercom access. All but the 
intercom key may be assigned via 
programming to features or CO/ 
PBX line access. 
02.15 All EKTs feature modular 
handset cords and are connected 
to the system via 4-conductor 
modular line cords. 
02.20 Direct Station Selection 
Console 
02.21 An optional Direct Sta- 
tion Selection (DSS) console (Fig- 
ure 9) is availablie for systems in 
which the volume of incoming 
calls requires a dedicated cali-an- 
swering position. The DSS is 
equipped with up to 56 station 
keys, an intercom key, an All Call 
Page key, Message Waiting/ 
Flash key and a Night Transfer 
key (its dimensions are the same 
as the EKT). Both 
Strata sys- 
tems may be equipped with one 
or two DSS consoles, which may 
operate simultaneously. 
02.22 A 20-key EKT, which var- 
ies from the standard EKT only in 
different dedicated key functions 
and lacks an intercom key (key is 
on the DSS), must accompany 
each DSS. 
02.23 In the Strata XJ& 
only, one or two additional DSS 
consoles may be optionaliy added 
to either system as Busy Lamp 
Field consoles. Their only func- 
tion is to provide station status 
information. 
03 ELECTRICAL 
CHARACTERISTICS 
03.01 The electrical character- 
istics of the system are summa- 
rized in Table A. 
03.02 The HKSU operates from 
an internal 24 VDC power supply, 
which connects to a nominal 117 
VAC, grounded wall outlet.
