SECTION 500 
INSTALLATION 
Digital Key Telephone Systems 
500.1 SITE PLANNING 
Selection of a suitable location is the most basic, yet 
most critical consideration in the installation of a 
telephone system. The following should be consid- 
ered when choosing an appropriate location for 
equipment installation: 
Ample space must be allowed to remove the 
KSU cover, to access assemblies and cards 
within the cabinet and allow space for the MDF 
(Main Distribution Frame). 
Location of CO/PBX line terminations must be 
considered when selecting a location for the 
KSU. In the case of telephone company line, 
FCC approved connectors supplied by the tele- 
phone company, should be within 5 feet (1.5 
meters) of the cabinet/main distribution frame. 
To minimize the length of cable runs between 
the stations and the system KSU, the location 
of the majority of the telephone sets (stations) 
should be taken into consideration when select- 
ing a location for the cabinet. 
A well ventilated, and well lighted area having 
an optimum temperature range of 60 degrees 
to 80 degrees F and a relative humidity range 
of 5 to 90% (non-condensing) must be pro- 
vided. 
Area lighting should be adequate for installation 
and maintenance of the system. Hazardous or 
flammable materials should be removed from 
the vicinity. The immediate area must not be 
subject to flooding or excess moisture. The 
KSU should be isolated from areas of moving 
machinery or equipment. It is also recom- 
mended that static electricity-producing carpets 
not be installed in this area. 
A separately fused, dedicated 117 volts AC, + 
lo%, 15 Amp., 60 Hz, single phase, 3-wire 
(parallel blade with ground) power outlet should 
be located within 5 feet (1.5 meters) of the 
system power supply. 
The KSU and main distribution frame should be 
placed in an electrically noise free environment, 
isolated and shielded from equipment that 
causes electromagnetic interference (EMI) or 
radio frequency interference (RFI). Examples 
of electrical noise are rotating electrical machin- 
ery and arc welding equipment, refrigerators, 
copy machines, etc. Floor coverings that gen- 
erate static electricity should also be avoided. 
. The system KSU should not be installed close 
to any equipment which may produce RFI (Ra- 
dio Frequency Interference) such as a radio 
frequency transmitter. 
. 
If the system is to be installed in a location prone 
to lightning strikes, provide lightning protection 
on the power line, any station cable runs outside 
the building, and CO lines. 
A. System Grounding 
To ensure that the system will operate properly, a 
good earth ground is required. Use of the Telco 
ground (source not demark) or a metallic COLD 
water pipe usually provides a reliable ground path. 
Carefully check that the pipe does not contain insul- 
ated joints that could isolate the ground. In the 
absence of the COLD water pipe, a ground rod or 
other source may be used. A no.12 AWG copper 
wire should be used between the ground source and 
the KSU (25 feet maximum). The farther from the 
ground source, the larger the ground wire used 
should be. The wire should be kept as short as 
possible and can be connected to the ground lug 
provided on the lower left side of the backplane on 
the KSU with the cover off. 
B. Lightning Protection 
The Starplus Digital (SPD) Key Telephone System 
should have Central Office lines and OPX stations 
protected with proper lightning surge arresters. This 
will provide protection from damaging surges on 
sensitive cabling by non-direct lightning strikes. 
The protection should contain a compliment of three- 
element gas-discharged tubes to ground high poten- 
tial surges, and associated circuits to absorb and 
filter lower level surges. This type of lightning pro- 
tection is available through telephone equipment 
supply houses. Care should be taken to ensure that 
such protection devices are installed in accordance 
with the manufacturers instructions and to ensure 
that no more than one set of protectors be installed 
on central office lines at the installation premises. 
Improper installation can be a serious safety hazard. 
Failure to provide the proper lightning protection will 
increase maintenance expense and require more 
available spare parts. 
500.2 
SPD 1428 INSTALLATION PLANNING 
Prior planning of the installation will aid in a smooth 
cut-over and a satisfied customer. Select a suitable 
location for the system. Determine -the number of 
Issue 1, November 1991 500-l  
						

							telephones of each type, and the number of CO/Sta- 
tion ports from the sales contract and discussions 
with the customer. 
NOTE: On/y 
one sfafion set is allowed per digital 
extension number. If is not possible to bridge digifal 
station ports so that an extension number may ap- 
pear in more than one location. 
. 
0 
4 . 
. 
* Programming information should also be gath- 
ered from the customer at this time so that the 
system may be programmed either before, or 
while the system is being installed. 
Determine the location and type of each tele- 
phone, and mark floor plans accordingly. 
Determine the location for the operator stations, 
and mark the floor plans. 
Arrange for power cabling (if necessary) and 
station cabling of the site. 
If the system is to be installed in an area subject 
to frequent lightning storms, consideration 
should be given to providing additional lightning 
protection on the CO lines beyond what is 
provided by the local telephone operating com- 
pany. 
NOTE: Installers should be trained and thoroughly 
familiar with the basic components of the SPD 1428 
before attempting installation of this product. 
500.3 SPD 1428 COMMON EQUIPMENT 
A. Basic Key Service Unit with Power Supply 
(BKSU) 
The SPD 1428 Basic Key Service Unit is a system 
which comes fully configured for four (4) 
CO/PBX/Centrex lines and eight (8) Stations. The 
basic KSU also contains one (1) RS-232C l/O port, 
one (1) DTMF Receiver, one (1) connector for Back- 
ground Music and Music on Hold, an on-board 300 
baud modem port, and one external page port. The 
basic KSU also contains two connectors for adding 
a 2X4 CO/Station Expander module (J9 and JlO), 
an optional I/O module that adds one additional 
RS-232C port and one RS-422 port, and an optional 
1200 baud modem module can be added to increase 
the speed of transmission of the on-board modem 
port. A reset (halt) switch and a BGM volume control 
are also mounted on the PCB. In addition two con- 
nectors are provided for adding an Expansion KSU 
which will allow the system to expand to a total of 14 
COIPBWCentrex lines and 28 digital station ports. 
Refer to Figure 500-l for a PCB layout and location 
of connectors. 
Power Sut3pl~ 
The power supply, installed in the KSU at the time of 
manufacture, has an input voltage of 117 VAC +lO%. The power supply provides power, a fil- 
tered/unregulated 512 VDC, to the main key service 
board. A slo-blow 1.5 amp fuse on the AC side of 
the transformer provides the necessary fire and 
overload protection. Power is regulated and distrib- 
uted to stations / circuitry in the system on the main 
key service board. The power supply and cabinet 
meet all safety requirements to comply with UL 1459 
Second Edition and CSA 0.3 standards. 
. 
S&In- . 
Four green LED’s are located on the main key station 
board along the top of the PCB. Two of the LED’s 
(DS2 & DS3) indicate the presence of +5 & -5 volts. 
LED’s DSl and DS5 indicate the presence of +12 
VDC used to supply power to the key stations (one 
LED per four stations). An extinguished LED indi- 
cates the absences of the associated voltage. 
A red LED (DS4) located in the lower right portion of 
the PCB provides a system “heart beat” indication. 
SPD 1428 BKSU Mountina: 
The SPD 1428 Basic Key Service Unit (BKSU) is 
housed in a wall mountable cabinet which contains 
the Key Service board (KSB), Power Supply and 
pre-wired connectors for stations and CO Line inter- 
face. Once the area for the telephone equipment has 
been selected, mount a plywood back board to the 
wall. The back board size will vary depending upon 
the size of the MDF. The entire system and frame 
can be mounted on a 4’ x 6’ x 3/4” plywood. If 
mounting the KSU alone, the minimum back board 
size is 25” x 17” x 3/4”. A fully loaded KSU can weigh 
approximately 15 Ibs. Make certain proper mounting 
procedures are followed. 
NOTE: Check local building and electrical codes 
before mounting the system. For example, certain 
areas may require a flame retardant plywood back 
board. 
Mount the cabinet to the plywood using 3/4” #12 
pan-head sheet metal screws such that the top of the 
KSU is approximately three feet (1 meter) from the 
ceiling, and bottom is four feet (1.2 meters) from the 
floor. 
Use the mounting template supplied with the cabinet 
to locate the mounting holes. Refer to Figure 500-2. 
Drill the holes and mount the KSU. 
Groundinq 
A No. 12 AGW copper wire should be used to 
connect a ground between the ground source and 
the KSU (25 feet maximum). A two position terminal 
strip P3 is located along the bottom edge of the main 
key service unit and is accessible through the bottom 
of the KSU. One terminal position can be used to 
connect the ground wire from a ground source and

CPU and Me- 
The SPD 1428 system is controlled by a 16-bit 
(68000) main micro-processor which controls all sys- 
tem functions including the PCMflDM voice switch- 
ing under the direction of ROM and RAM software 
coding. The main key service board is responsible 
for all control functions, execution of all logic opera- 
tions and control of system modules including control 
over the circuitry necessary for voice switching and 
conference connections. The main key service 
board is also responsible for all system tones, sys- 
tem timing, and station status control. In addition the 
main key service board provides software and hard- 
ware support of the following: 
Real Time clock. 
Watch dog timer and recovery. 
PCB status as to presence/absence of mod- 
ules for automatic software configuration 
setup. 
State/event software design. 
Backup of customer database RAM memory 
via a “supper Cap” (supper capacitor). 
System software is provided in EPROM memory and 
is installed on the main key service board. The 
system contains (512) kilobytes of EPROM storage 
and is equipped with 128K of “battery’-backed static 
RAM. Provisions have been made on the card to 
address up to (2) megabytes of EPROM memory 
and up to (2) megabytes of static RAM. 
An option “dip” switch (SWl) located on the main key 
service board allows the system EPROM memory to 
be configured utilizing different size EPROM chips. 
1 Megabit, 2 Megabit, 4 Megabit and 8 Megabit chips 
may be used to provide the generic software. Refer 
to Sec. 800 Maintenance &Troubleshooting for “dip” 
switch (SWl) settings for various allowable configu- 
rations. 
A separate option strap (J26) allows the use of either 
256Kbit, 1 Megabit, or 4 megabit static RAM chips 
to be used for RAM memory.Refer to Sec. 800 
Maintenance & Troubleshooting for the option strap 
choices. 
CO Line/Station Interfaces: 
The BKSU contains the necessary circuitry to con- 
nect four (4) CO/Centrex/PBX loop start lines and 
eight (8) Digital Key Telephones to the system. This 
card also contains one additional voice (transmit) 
path for external paging. 
The main key station board contains four (4) Central 
Office, Centrex or PBX loop start, line interfaces. The protection circuitry to allow the system to be 
classified as a fully protected system are located on 
the card for each CO circuit. The CO circuits are 
equipped with current sensing circuitry that identifies 
distant end disconnect (loop supervision). Each CO 
line interface design also provides proper fusing or 
protection to comply with the requirements of UL 
1459 Second Edition and CSA 0.3 standards. CO 
lines are connected to the system via RJ-11 modular 
jacks mounted on the bottom of the main key service 
board. 
The main key station board also provides the inter- 
face for eight (8) Digital Key Telephones using two 
(2) 64 kilobyte channel arrangements. Stations con- 
nect to the board via the MDF through a 50 pin 
connector located inside the KSU. Each station 
connection requires four (4) wires to connect to the 
board. 
A Digital DSS/DLS Console, and Single Line Tele- 
phone Adapter (OPX) or other specifically designed 
adapter with a digital interface can be assigned to 
any one of the interface circuits. The Key Station 
interface circuits are protected from mis-wiring and 
over-current. 
The main key service also contains an on-board 
modem that is capable of transmitting data at a rate 
of 300 baud. The modem supports and is compat- 
ible with the Hayes command protocol. The Bell 
System (Western Electric) standards 103 and 212A 
for modem design is incorporated into the design of 
this modem. The modem operates on-line in both 
Full and Half duplex modes. An optional 1200 baud 
module may be added to the main key service unit 
to allow transmission at the rate of 1200 baud.
