							C. 2x4 CO/Station Expander Module 
The SPD 1428 2x4 CO/STA Expander Module is a 
Two (2) CO by four (4) Key Station interface module 
that plugs onto the main key service board of the 
basic KSU or the Expansion Key Service board of 
the Expansion KSU with the use of two ribbon ca- 
bles. This module is a combination board that con- 
tains the necessary circuitry to connect two (2) 
CO/Centrex/PBX loop start lines and four (4) Digital 
Key Telephones to the system. This card also con- 
tains one additional voice (transmit) path for external 
paging, and a connector for adding one application 
module (i.e. DTMF Receiver) to the system. 
NOTE: When the 2x4 Expander module is installed 
, 
in the Expansion KSU two CO ports and four Station 
ports become unusable. This DOES NOT however 
reduce the total system capacity of 14 CO lines and 
28 Stations. 
The 2x4 CO/STA Expander Module provides the 
interface for two (2) Central Office, Centrex or PBX 
loop start, lines. The protection circuitry necessary 
to allow the system to be classified as a fully pro- 
tected system are located on the card for each CO  Digital Key Telephone Systems 
STARPLUS@ SPD 1428 & 2856 
circuit. The CO circuits are equipped with current 
sensing circuitry that identifies distant end discon- 
nect (loop supervision). The module 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 connectors mounted on 
the bottom edge of the board. 
The 2x4 CO/STA Expander module also provides 
the interface for four (4) Digital Key Telephones 
using two (2) 84 kilobyte channel arrangements. 
Stations connect to the board via the MDF through 
a 50 pin connector located on the main key service 
board inside the basic KSU or a similar connector on 
the expansion key service board when installed in 
the EKSU. Each station connection requires four (4) 
wires to connect to the board. 
A Digital DSS/DLS Console, and a 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.

400.5 SPD 1428 & SPD 2856 TERMINALS 
A. 34 Button Digital Terminal (Enhanced) 
The 34 button Digital Terminal is a new line of Digital 
electronic telephone terminals. The line consists of 
an Enhanced (non-display) and an Executive (with 
display). This new line of telephones will be designed 
to operate with the new line of Starplus digital key 
and PBX systems. The 34 button Digital Terminal is 
connected to the KSU via a four wire (two twisted 
pair) connections from an appropriate electronic ter- 
minal interface board. 
The terminal communicates to the KSU through two 
(2) 64K digital channel arrangements. One channel 
is used as the primary voice channel, a second is 
used for terminal to KSU command transmission. 
Power is also provided to the terminal via the four (4) 
wire connection. 
The 34 button Digital terminal key board PCB pro- 
vides long life “super bright” Light Emitting Diodes 
(LED’s) and button assemblies that protrude through 
the top housing. The buttons are small rectangle in 
shape with a clear end for proper LED visibility and 
diffusion. The 34 button Digital Terminal has 34 
buttons all containing LED’s plus a 12 key dial pad. 
The 34 button Digital Terminal scans the key board 
for dial pad and button debounces and depressions 
for command transmission to the KSU. The keyset 
has the following buttons defined as follows: 
Display and Non-Display 
- 12 Dial Key Pad* 
- 28 Flexible Buttons 
- 1 ON/OFF button 
(fixed) 
- 1 MUTE button (fixed) 
- 1 SPEED button (fixed) 
- 1 FLASH button (fixed) 
- 1 TRANSfer button (fixed) 
- 1 HOLD button (fixed) 
l All buttons except the 12 Dial key pad have an LED 
associated with it. Refer to Figure 400-9 for default 
button mapping. 
Each 34 button Digital Terminal is equipped with a 
unit that enables the telephone to be used handsfree 
in two-way conversations. The user activates the 
speakerphone by pressing the ON/OFF button (LED 
lights steady). To terminate a speakerphone call the 
ON/OFF button is toggled OFF (LED extinguished). 
The MUTE feature is used in conjunction with the 
speakerphone option. To mute.the speakerphone 
microphone the MUTE button is pressed (LED lights 
steady), to reactivate the microphone the MUTE 
button is pushed again (LED extinguished). 
Several programmable options control the speaker- 
phone operation. Each digital terminal can be pro- 
grammed for full speakerphone operation, or 
monitor/On-Hook dialing capabilities with no full 
speaker phone operation. 
When Automatic pre-selection is enabled at the sta- 
tion when any button is pressed (i.e. CO, DSS, Page 
etc...) the station and speakerphone is automatically 
activated. 
Separate “slide” switches are provided on the front 
of the Starplus Digital Terminal to adjust the volume 
of the voice and tones presented to the terminal 
speaker. 
- The “SPKR VOL” will control all voice sig- 
nals sent to the speaker i.e. Speaker Phone 
conversations, BGM, and Page an- 
nouncements. 
- The “RING VOL” will control all tone signals 
presented to the speaker i.e. Ringing, 
splash tones, Camp-On etc... Muted ring- 
ing will also be controlled by the “RING 
VOL” slide switch. The Muted ringing vol- 
ume will be proportionately quieter than 
normal tinging based on the current switch 
setting. 
H-T-P Switch: 
A three (3) position slide switch is located on the front 
of the Digital Display Terminal that controls the 
method of receiving intercom calls. 
- The “H” position allows intercom call an- 
nounce with hands free reply. 
- The ‘T’ position provides Tone only inter- 
ringina. 
- 
- The ‘P” position allows Call Announ
