Starplus@ DHSTM Introduction 5  
						

							1.2 SYSTEM TECHNOLOGY 
The Starplus Digital Hybrid System (DHS) is 
a lily digital key telephone system comprised of an -. 
application configurable, expandable Key Service Unit (KSU) platform. The common system architecture 
supports three digital telephone models and an expandable D/A, A/D analog device interface. nie DHS is 
designed to meet the telecommunications needs of small to medium sized business offices. The DHS 
incorporates state of the art digital technology for voice switching and call processing utilizing Pulse Code 
Modulation and Time Division Multiplexing (PCMTDM). The Starplus DHS family is engineered to 
allow migration of the Stat-plus DHS digital terminals and. terminal accessories throughout the entire 
product line. ISDN-like, 2B+D technology complements the system architecture and capabilities. On one 
industry standard twisted pair, key telephones perform all system functions and voice communications. 
The DHS is a non-blocking switch, with no loss or degradation of voice signals. The system is stored- 
pro,- control and utilizes a 16-bit, 8 MHz microprocessor. Memory consists of 5 12K bytes of ROM 
(Read Only memory) and 128K bytes of RAM (Random Access Memory). 
When analog device interface is required, a 2-port Single Line Telephone (SLT) Adapter may be 
connected to any one digital station port. The 2B+D technology allows the Starplus DHS to split one 
digital key telephone port voice channel (Bl) and the second voice channel (B2) to provide two 
independent SLT-type device interfaces. The 2-port SLT Adapter may be expanded with the 2-port SLT 
Expansion (housed in the 2-port SLT Adapter housing). 
The 2-Port SLT Adapter and 2-Port SLT Expansion each require one dedicated digital station port. 
The application of analog devices in the Starplus DHS has the effect of two-to-one 
port gain. For every single digital port used to interface a 2-port SLT 
adapter/expansion two analog ports are available. 
The Starplus DHS Basic KSU is shipped equipped to interface three (3) loop start CO lines and eight (8) 
digital key telephonesn-Port SLT Adapters. The standard 3X8 CO/Station interface module is available 
separately and called the “3X8 Expansion Module.” 
Two (2) 3X8 Expansion Modules may be added to the 
Standard 3X8 Module in the Basic KSU for a maximum conf@ration of 9X24 (CO lines/stations). 
Alternately, a “6-Port CO Module” may be substituted for one 3X8 Expansion Module allowing for greater 
flexibility. 
The maximum capacity of this configuration is 12/l 6 (COSta). Regardless of the 
configuration, the system has sufficient resources to allow completely non-blocked access to all facilities 
(intercom and CO lines). 
A Standard Background Music/Music-On-Hold (BGMMOH) Module is also equipped in the Basic KSU. . 
A external music source may be connected to this interface via a one-eighth inch phono plug for 
BGMMOH listening. All system features are supported by the equipment provided in the Basic KSU ’ 
except External Call Forward (ECF), Direct Inward System Access (DISA), Automatic Busy Redial, 
Unsupervised CO Line Conference, Dial Tone Detection, Loud Bell Control, External Paging, the second 
BGM channel, and RS232 serial ports for SMDR and Remote Pro_gramrning. 
When equipped, the Option Module replaces the Standard BGMMOH Module and provides the resources 
for the features above. The Option LModule provides two (2) DTMF receivers and two (2) Tone Detectors 
specifically for ECF, DISA. Unsupervised CO Line Conference, and Dial Tone Detection. Note: SLT 
operations do 
NOT use Option Module resources. i. 1

2.4 Power Supply 
The power supply circuitry of the Starplus@ DHSTM incorporates a linear design transformer with a choice 
of input voltage taps. The transformer primary windings are shipped wired for 117vac applications. A 
factory insulated tap wire may alternately be connected for 230vac applications. Since the power supply is 
linear in design the output voltage varies between 2 1.6vdc and 32vdc depending on load and stability of the 
input voltage. The output voltage is delivered to the CPU board for distribution and rectified there for logic 
and control voltages. 
Two fuses are equipped on the power supply board, one for ac input over-voltage protection and one for dc 
output over-voltage protection. A DPDT (Double Pole Double Throw) switch is accessible Ii-om outside of 
the KSU when the KSU cover is in place. The DPDT switch will simultaneously switch AC input and DC 
output circuits on and off. In the event battery backup operation is desired and equipped via the optional 
Stat-plus@ BBU (Battery Backup Unit), the KSU switch may be used to switch of5’on power from both 
sources. 
The power supply wiring harness is equipped with a Mate-n-lock connector on the DC output for 
connection of the Stat-plus@ BBU. When equipped the BBU will maintain complete system operation 
during commercial power outages. A current draw/configuration chart is included in this document for
