1 GENERAL 2 SYSTEM TECHNOLOGY 
1.00 
This chapter provides a discussion of the 
technology employed in the STRATA DK system 
design, and a detailed description of the system 
hardware, including the basic equipment cabinet 
(key service unit), PCB options, and system pe- 
ripheral equipment. A description of system con- 
trols and indicators is also provided. 
1 .I 0 System Description 
1 .I 1 
A STRATA DK system consists essentially 
of a key service unit (KSU) cabinet (Figure 2-l) 
which houses the power supply and a number of 
PCBs. The quantity and type of PCBs, telephones, 
and peripherals installed depends on the user’s 
requirements. The primary differences between 
models are KSU sizes, PCB capacities, and power 
supplies. 
1.12 Hardware for all three system types is iden- 
tical, with the exception of the KSUs and power 
supplies. Differences between models are identi- 
fied, as applicable. 
2.00 Custom Electronic Circuitry 
2.01 STRATA DK system circuitry employs Large 
Scale Integration technology to increase system 
efficiency while allowing a reduction in physical 
size. Use of CMOS circuits, when applicable, 
minimizes the system’s power requirements. 
2.10 Microprocessors 
2.11 Main Microprocessor. 
The systems em- 
ploy a 16-bit, 68000-type microprocessor, operat- 
ing at a speed of 8 MHz, for stored program control. 
The main microprocessor is located on the Com- 
mon Control Unit (PCTU or PCTUSI PCB). 
2.12 Local Microprocessors. Local micropro- 
cessors are located on most PCBs and in elec- 
tronic telephones. The local microprocessors in 
the KSU are 8-bit, TMP90C840-type microproces- 
sors, which operate at a clock speed 
of 10 MHz.

SECTION 200-096-202 
FEBRUARY 1991 
2.20 Stored Programming 
2.21 System Operating Software. 
System op- 
erating software is stored in ROM, and is revised 
only by Toshiba software engineers. 
2.22 Configuration and Custom Programming. 
Each system’s individual configuration and cus- 
tom programming is stored in RAM. The contents 
of system RAM is user-developed and -pro- 
grammed based on the system’s configuration 
and the user’s requirements. System RAM is pro- 
tected by a lithium battery with a shelf life of 
approximately six years. 
2.30 Pulse Code Modulation (PCM) 
2.31 
PCM technology allows fully non-blocking 
intercom and outside line talk paths. Talk paths 
operate through digital switching, as opposed to 
analog crosspoints. Analog-to-digital and digital- 
to-analog conversion is accomplished by CODEC 
integrated circuits. 
3 KEY SERVICE UNITS (KSU) 
3.01 The STRATA DK KSUs consist of single, 
free-standing cabinets that can be configured for 
either wall or table-top mounting. One-inch rubber 
feet on the base of the cabinet ensure that proper 
clearance is maintained when the KSU is table-top 
mounted. The KSU interior houses the PCBshelves 
and the power supply. 
3.02 External dimensions and approximate 
weights for the DK24, DK56, and DK96 models are 
listed below. Weights are based on cabinets con- 
taining a full complement of PCBs. 
DK24 Height: 10.6 in. (269 mm) 
Width: 16.0 in. (406 mm) 
Depth: 9.0 in. (229 mm) 
Weight: 19.4 Ibs (9 kg) 
DK56 Height: 15.0 in. (381 mm) 
Width: 16.0 in. (406 mm) 
Depth: 9.0 in. (229 mm) 
Weight: 37.5 Ibs (17 kg) 
DK96 Height: 18.6 in. (475 mm) 
Width: 19.6 in. (500 mm) 
Depth: 9.0 in. (229 mm) 
Weight: 55.1 Ibs (25 kg) 
3.10 DK24 KSU Interior 
3.11 
The DK24 KSU interior has one shelf (Figure 
2-2) with seven available PCB slots, labeled PCTU 
and SO1 w S06. Only the PCTU slot serves a 
dedicated function. 
FIGURE 2-2-DK24 KSU INTERIOR 
3.12 Each PCB slot (SO1 N S06) incorporates a 
standard 40-pin female connector located in the 
same vertical position on the KSU’s backplane. 
This standardization enables any of the optional 
PCBs to be installed in any slot. The PCTU slot 
incorporates the same 40-pin female connector, 
but it is set 0.25-inch higher, so that only a PCTU 
or PCTUSl PCB may be installed in the slot. 
3.13 The power supply is factory-installed, 
mounted vertically into the right side of the PCB 
shelf, and is secured with two combination slotted/ 
Phillips mounting screws at the right side of the 
cabinet. 
3.20 DK56 KSU interior 
3.21 The DK56 KSU interior also has just one 
shelf (Figure 2-3), but with nine available PCB

slots. These slots are labeled PCTU and SO1 w 
S08; only the PCTU slot serves a dedicated func- 
tion. 
3.22 Each PCB slot (SO1 N S08) incorporates a 
standard 40-pin female connector located in the 
same vertical position on the KSU’s backplane. 
This standardization enables any of the optional 
PCBs to be installed in any slot. The PCTU slot 
incorporates the same 40-pin female connector, 
but it is set 0.25-inch higher, so that only a PCTU 
PCB may be installed in the slot. 
3.23 The power supply is factory-installed, 
mounted horizontally above the PCB shelf, and is 
secured with four combination slotted/Phillips 
mounting screws. 
3.30 DK96 KSU Interior 
3.31 The cabinet interior has two shelves (Figure 
2-4). The top shelf has eight available PCB slots 
labeled SO1 N S08. The bottom shelf has seven 
available PCB slots labeled PCTU and SO9 N S14. 
Only the PCTU slot serves a dedicated function. 
3.32 Each PCB slot (SO1 w S14) incorporates a 
standard 40-pin female connector located in the 
same vertical position on the KSU’s backplane.

3.33 The power supply is factory-installed, 
mounted vertically (to the right of the two PCB 
shelves), and is secured with four combination 
slotted/Phillips mounting screws. 
4 POWER SUPPLIES 
4.00 STRATA DK systems incorporate single- 
chassis, switching-type power supplies. The power 
supplies for the three models are functionally iden- 
tical (except for power capacity), although they 
differ in appearance due to cabinet sizes and 
mounting considerations. The DK24 model uses a 
PPSU24 power supply (Figure 2-5), DK56 uses a 
PPSU56 (Figure 2-6), and DK96 uses a PPSU96 
(Figure 2-7). 
4.01 The power supplies generate *5VDC and 
-24VDC output voltages (that are protected by 
mechanical circuit breakers located on the power 
supply front panel). Input voltage is provided by a 
standard 117VAC, 15 amp circuit. Electrical char- 
acteristics include: 
l Primary Power 
l Input AC: 85VAC w 135VAC

Reserve Power 
4.11 
Twocustomer-supplied, 12-volt batteries (80 
ampere hours maximum) can be connected in 
series to the system as a power failure backup. In 
the event of a power failure, the system automati- 
cally switches over to battery power without any 
interruption to existing calls or other normal sys- 
tem functions. The length of time reserve power 
operates depends on the system, size and number 
of batteries provided, and the system load. Typical 
reserve power duration estimates are provided in 
Table 2-A.
