04.30 Printed Circuit Board Functions 
04.31 Complete with all available options, 
both 
Strata systems utilize eight different 
PCBs, with a maximum of 12 for 
Strata 
XI/e and 19 for Strata XXe. They are: 
NOTE: 
Several optional features are now per- 
formed by external modules, see Para- 
graph 05 for information on peripheral 
equipment. 
HCOU: An interface between the HKSU and 
the central office or P5X lines. Ring detec- 
tion, hold and dial outpulsing are performed 
by this PC5. Depending upon local CO 
requirements, each CO/PBX line can be 
programmed for DTMF or rotary dial out- 
pulsing. Each HCOU PC5 serves up to three 
CO/PBX lines. 
HPLU: An optional PC5 that is required 
when using the optional HOL5 or HTIB mod- 
ules Each HPLU PC5 interfaces one HOLB 
or HTl5 module. The HPLU serves up to 
three CO/PBX lines and replaces the HCOU 
that would usually serve these lines. 
HSTU/STAU: An interface between the 
HKSU and EKTs, which includes the sys- 
tem’s solid-state space division matrix. Each 
HSTU/STAU serves up to eight EKTs . Two- 
pair wiring is required for each EKT; one 
pair carrying voice and the other pair carry- 
ing control data to and from the EKT. 
l STAU: Contains the additional solid- 
state crosspoints required in a 
5trata 
XXe 
system. Each STAU mounts 
directly on the HSTU, providing access to 
CO lines 13 - 21, plus two additional 
intercom paths for those eight stations. 
HCAUICAAU: The CAAU is required and 
mounts directly on the HCAU to form a sin- 
gle unit. All system control functions are 
performed by the single-chip microprocessor 
located on the HCAU. The system program 
stored in ROM, the RAM for system opera- 
tions and the battery-protected RAM for sys- 
tem data storage are located on the CAAU. 
HCBU: Contains a microprocessor that 
serves to off-load the main CPU by handling INSTALLATION INSTRUCTIONS 
SECTION 300-020-200 
JULY 1986 
the routine and repetitive data transmission 
tasks to and from peripheral equipment. It 
also provides the interface for two DSS con- 
soles. One HCBU is used in 
Strata Xi/e, 
while two are required in any Strata 
XXe system that is equipped with more 
than 32 stations or that requires one or two 
BLF consoles. BLF consoles are not avail- 
able for the 
Strata X//e. 
HINU: Generates system tones and provides 
the switching matrix for the delivery of 
tones for both paging and intercom connec- 
tions (one per system). Houses circuitry and 
connection points for the relay services, 
music-on-hold and external page amplifier. 
Also is a host PC5 for the SMOU. 
l SMOU: The SMOU is an optional 
music-on-hold source that provides elec- 
tronic synthesized music. One of two 
musical tunes are available, selected via 
a switch on this PCB. 
04.40 Power Supply 
04.41 The system requires 24 VDC, which is 
provided by the internal power supply: 
Xl/e = HPSU 8120 XX= = HPSU 9120 
HPSU requires 117 VAC, 60 Hz, with a permis- 
sible AC input voltage range of 90 - 130 VAC. 
CAUTION! 
in accordance with all appiicable eiectri- 
cal codes and Article 480, National 
Electrical Code, the HPSU, HP5U, bat- 
tery, battery rack and interconnecting 
wiring must be instal/ed and serviced by 
on/y qualified installers. Carefully read 
the Vnstailation Instructions” enclosed 
with each item. 
04.42 An optional battery back-up unit 
(HPBU-8) is available. It is a PC5 that mounts 
inside the power supply housing (Figure 3) and 
is connected to the female 3-prong connector 
inside the power supply’s case. Secure the 
HPBU with the two provided screws. 
04.43 The HPBU is then connected via the 
terminal block to the recommended battery 
pack (which is customer-supplied, consisting 
of two 12 VDC, maintenance-free, automobile- 
type batteries - 80 amp/hour maximum 
rating). With the optional battery back-up 
assembly installed, all functions of the system

will continue to operate for several hours (the 
actual time period is in direct ratio to the type 
and size of batteries selected). 
04.44 A Toshiba 
Strata electronic key 
telephone system requires a solid earth 
ground. Failure to provide such a ground may 
lead to confusing trouble symptoms in the sys- 
tem and, in extreme cases, circuit board fail- 
ure. In most installations, within the continen- 
tal United States, the ground provided by the 
“third wire ground” at the commercial power 
outlet will be satisfactory for all 
Strata 
requirements. However, in a small percentage 
of installations, this ground may be installed 
incorrectly. Therefore, prior to installing a sys- 
tem, the third wire ground must be tested for 
continuity by either measuring the resistance 
between the third prong terminal (earth 
ground) and a metal cold water pipe, or by 
using a commercially available earth ground 
indicator. If neither procedure is possible, then 
the test procedures outlined in Paragraph 
04.45 should be performed. 
WARNING! 
Hazardous voltage is exposed during the 
following test. Use great care when 
working with AC powerfine voltage.

Pack 
reading obtained should be 90 - 130 VAC. 
3) Move one of the meter probes to the third 
prong terminal (GND). Either the same reading 
or a reading of 0 volts should be obtained. 
4) If the reading is OV, leave one probe on the 
GND terminal and move the other probe to the 
second voltage terminal. If a reading of OV is 
obtained on both voltage terminals, the outlet 
is not properly grounded. Omit Steps 5 and 6 
and proceed directly to Step 7. 
5) If a reading of OV on one termi;..;! and a 
reading of 90 - 130 VAC on the other terminal 
is obtained, remove both probes from the out- 
let. 
6) Set the meter on the “OHMS/Rxl” scale, 
place one probe on the GND terminal and the 
other probe on the terminal that produced a 
reading of OV. A reading of less than 1 ohm 
should be obtained. If a reading of more than 1 
ohm is obtained, the outlet is not adequately 
grounded. 
7) If the above tests show the outlet is improp- 
erly grounded, that condition should be cor- 
rected by a qualified electrician (per Article 
250 of the National Electrical Code) before the 
Strata system is connected. 
04.50 Power Supply Installation 
04.51 Before installing the power supply 
(HPSU) in the HKSU, it should be bench tested. 
FIGURE 3 - HPBU INSTALLATION 
04.45 The test procedures are as follows: 
1) Obtain a suitable voltmeter and set it for a 
possible reading of up to 250 VAC. 
2) Connect the meter probes between the two 
main AC voltage points on the wall outlet. The
