SECTION 400 
GENERAL 
400.1 SYSTEM TECHNOLOGY 
The Starplus Family of Digital Key Telephone sys- 
tems is comprised of two fully digital hybrid key 
telephone systems, the SPD 1428 and SPD 2856. 
These systems are designed to meet the telecom- 
munications needs of a small to medium sized busi- 
ness offices. Both systems incorporate state of the 
art digital technology for command processing and 
voice switching utilizing a Pulse Coded Modula- 
tion/Time Division Multiplexing (PCM/TDM) voice 
control module. The family of Starplus Digital sys- 
tems are also engineered to allow migration of the 
family of Starplus digital terminals and teminal ac- 
cessories throughout the entire product line. In ad- 
dition standard 2500-type telephone devices are 
supported by use of Single line interface PCB’s and 
or SLA (OPX) adapters. 
The SPD 1428 is the smallest member of the Star- 
plus Digital family and fully configured supports a 
maximum of 14 CO/PBX/Centrex lines and 28 digital 
station devices. The SPD 1428 is a “flatpack”, or 
single mother board system with plug on modules 
expanding the system via expansion and expander 
modules configured with either two (2) 
CO/PBX/Centrex lines by four (4) stations or four (4) 
COIPBXICentrex lines by eight (8) stations. A com- 
plete system capacity allows for use of up to 112 time 
slots for Stations, CO Lines, DTMF Receivers, or 
Data switching Modules. This extends non-blocking 
access to all system resources. 
The SPD 1428 Basic KSU comes fully configured 
with power supply, Common control processor, 
PCM/TDM Voice switching matrix and interface cir- 
cuits for four (4) CO/PBWCentrex lines and interface 
circuits for eight (8) Digital terminal stations. The 
basic system is also equipped with one (1) RS-232C 
I/O port, one (1) DTMF receiver, a connector for one 
(1) Music On Hold channel that also provides for 
Background Music, and an on-board modem (300 
baud) that provides access to the system for data 
base programming or remote maintenance and or 
diagnostics. Modules to provide additional I/O ports, 
and an optional 1200 baud modem module can also 
be added to the system. 
The SPD 2856 system is the middle system in a 
family of Digital Hybrid Key Telephone systems and 
supports a maximum configuration of 28 
CO/PBX/Centrex lines and 56 digital station devices. 
The SPD 2856 is a typical KSU system with plug in 
PCB’s. The system capacity is expanded by install- 
ing four (4) circuit CO/PBX/Centrex lines by eight (8) 
DESCRIPTION 
circuit station expansion PCB’s. The complete sys- 
tem capacity allows for use of up to 112 time slots 
for Stations, CO Lines, DTMF Receivers, or Data 
switching Modules. This extends virtual non-block- 
ing access to all system resources. 
A basic SPD 2856 KSU ships complete with an 
on-board power supply. The CPB which is the only 
common equipment required for operation provides 
the microprocessor for command processing and 
Voice PCM/TDM switching. The CPB is also 
equipped with one (1) modular RS-232C l/O port, a 
connector for one (1) Music On Hold channel that 
also provides for Background Music, and an on- 
board modem (300 baud) that provides access to the 
system for data base programming or remote main- 
tenance and or diagnostics. Modules to provide 
additional I/O ports, and an optional 1200 baud 
modem module can also be added to the CPB. 
Both systems are installed using industry standard 
blocks, jacks and skinny wire cabling. This com- 
bined with the ability to program the system using a 
key terminal (digital display terminal) reduces instal- 
lation cost and maintenance requirements. 
All CO interfaces are equipped with transformer 
barriers, for system classification as an FCC fully 
protected system. Each CO circuit supports rotary 
(out-pulse) dialing and loop supervision (disconnect 
detection) under software control. The DTMF tone 
signals and system supervisory tones can be gener- 
ated in each keyset or on the main PCB. Both 
Starplus Digital systems use a proprietary tone plan 
for providing internal progress tones with the excep- 
tion of OPX stations which are provided with a “pre- 
cise” tone plan. 
The Stat-plus family of digital terminals include a 
display and non-display 34 button stations. Optional 
station terminals include a Digital DSWDLS Con- 
sole, and a Single Line adapter (Off-Premise Exten- 
sion (OPX) adapter) which are all upward and 
downward compatible to the entire Star-plus digital 
product line. 
The system architecture allows system program- 
ming changes to be made without interrupting state 
event software control of normal communications. 
Call processing continues while the customer data 
base is updated. All programming changes to the 
customer data base programming are made either 
from a digital terminal (digital display terminal) con- 
nected to Port 01 or from a data terminal or PC 
connected to either a I/O port or remotely via the 
on-board modem.

, 
The Starplus product line is tailored to meet imme- 
diate and long term customer needs. Most com- 
monly used features are activated by direct button 
selection. However, many functions may be alter- 
nately accessed by dialing specific codes or as 
another option by assigning these dial codes to a 
FLEX button on a digital terminal. This permits flex- 
ible use of the Starplus Digital systems. 
Future software enhancements and upgrades are 
easily retrofitted and installed in the system. This will 
in most cases provide backward compatibility with 
existing Starplus Digital hardware further reducing 
the cost to upgrade or add features to an installed 
system.

Power Sup&~ 
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 +12 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. 
The SPD 1428 system is controlled by a 16-bit 
(68000) main micro-processor which controls all sys- 
tem functions including the PCMnDM 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.
