F. 
G. 
H. and Random Access Memory (RAM) for cus- 
tomer data base programming. A lithium bat- 
tery is included for protection of the RAM 
memory. An RS232C connector for data base 
printout and SMDR is included. Feature Pack- 
age software is installed on this board at the 
factory. One (1) CCU is required per system. 
Central Office Interface Board (COI) 
Provides the interface for eight central offi 
(DTMF or Dial Pulse) loop start lines. The 
board can be removed or inserted with KSU 
power ON, however, the ‘Normal/Service” 
switch should be in the ‘Service” mode before 
removing or inserting the board into the system. 
An in-use LED for each circuit and a switch to 
take the board out of service are provided. 
The CO circuits are equipped with programma- 
ble current sensing circuitry that identifies dis- 
tant end disconnect loop supervision, if 
provided by the Central Office. 
Key Station Interface Board (KSB) 
Provides interface circuitry for eight Key Tele- 
phones. The KSB will support any Starplus 
Basic, Enhanced or Executive Key Telephone 
set. The KSB board can be inserted or re- 
moved with the KSU power ON, however, the 
“Normal/Service” switch should be in the “Serv- 
ice” mode before removing or inserting the 
board into the system. An in-use LED and a 
switch to take the card out of service are pro- 
vided. A DSS/DLS or Phone Box can also be 
assigned to any one of the circuits. The KSB 
circuits are protected from mis-wiring and over- 
current. 
Single Line Telephone Interface Board 
WT) 
The Single LineTelephone Interface Board pro- 
vides interface for eight (8) -24 vdc single line 
(2500 type) telephones. Single Line Telephone 
Interface Boards (SLT) and Key Station Inter- 
face Boards (KSB’s) are inter-changeable with- 
in the system. Both standard DTMF and 
message waiting (9OV) DTMF single line tele- 
phones may be used. A Single Line Board is 
required when connecting to a Voice Mail Sys- 
tem and In-Band integration is desired. An Ap- 
plication Board (APB) and a Ring Generator 
(RG) are required when installing Single Line 
Boards. 
480.3 OPTIONAL COMPONENTS 
-l 
A. Application Board (APB) 
The Application Board provides the matrix and 
controlling circuitry for DISA, unsupervised B. 
C. 
D. 
E. 
F. conference and one external page zone as well 
as the circuitry for two DTMF receivers and two 
DTMF senders to support a small number of 
single line telephones. The APB has provisions 
for the addition of a Single Line DTMFRS Unit 
(SLU), used to support larger quantities of sin- 
gle-line telephones, and an RS232C Module 
(RSM) to add an additional RS232C port for 
outputing SMDR information only. This port 
cannot be used for programming iocally or rt3 
motely via a terminal. The APB also has a 
connection for Recorded Announcement 
(RAN) input and its control contacts. 
RS232C Module (RSM) 
This RS232C Module (RSM) mounts on the 
Application Board (APB) and provides a second 
RS232C connector. This connector may be 
used to output SMDR data while the standard 
RS232C (located on the CCU) is used for sys- 
tem printout or Remote Administration. 
Single Line DTMF Receiver/Sender Unit 
(SW 
Used to expand the DTMF receivers and send- 
ers in the System to support single line telepho- 
nes. The module is added to the APB board 
and contains four DTMF receivers and one 
DTM F sender. 
Power Failure Transfer Unit (Pt7) 
There can be two Power Failure Transfer Units 
installed in the Basic KSU, each providing auto- 
matic direct cut-through connection of six 
CO/PBX lines to six single line telephones in 
case of commercial power failure or system 
processor failure. The single line telephones 
may or may not be intercom stations. For each 
PFT installed, there is one set of Loud Bell 
Control contacts provided. This unit can be 
removed or inserted with power on the KSU. 
There is a manual switch that activates the PFT 
for testing purposes. 
Battery Charging Unit (BC) 
The Battery Charging Unit (BC) installs into the 
External Power Supply Housing (EPH) and pro- 
vides the charging circuitry for a 24V dc battery 
package. The charging rate is 28V & at 0.5 
ampere for the Basic KSU. 
Single Line Ring Generator and lWIV 
Power Supply Unit (RG) 
Provides the 9OV ac, 20 Hz, ringing supply for 
supporting single line telephones and OPx’s. 
Also provides the voltage to light single line 
telephone M/W lights when Single tine Board 
cards are installed in the system. This unit 
plugs into the External Power Supply Housing.

							Hybrid Key Telephone System STARPLUS 2446EX 
One (1) unit is required when the system will be 
equipped with single line telephones. 
400.4 STATIONS 
A. Basic Key Telephone 
The Starplus Basic Electronic Telephone will 
operate on both Starplus Hybrid Key Telephone 
Systems. The Starplus Basic keyset is a fully 
modular instrument that features On-Hook dial- 
ing and Call Announce, Intercom, two (2) Vol- 
ume Controls, a Personal Directory, and a 12 
key “DTMF dial pad. 
Note: Full speakerphone operation or Call An- 
nounce with handsfree reply on intercom are not 
provided with the Basic Key Telephone. 
On the 2448EX Hybrid Key Telephone the Ba- 
sic keyset offers compatibility by providing a 
loop button as one of the fixed 14 feature func- 
tion buttons. This allows the Basic keyset to 
both place and receive transferred CO line 
calls. 
Note: Direct Incoming calls cannot be directed to the 
Basic keyset on the 2448EX. 
8. Enhanced Key Telephone 
The Starplus Enhanced Electronic Telephone 
(Fig 400-2) is a fully modular instrument with 14 
fixed feature/function buttons and 16 flexibly 
assigned buttons or 8 fixed feature/function 
buttons. This telephone also features an inte 
grated speakerphone, call announce with 
handsfree intercom, two (2) Volume Controls, 
Intercom select switch, and long life LED’s. 
C. Executive Electronic Telephone 
The Starplus Executive Key Telephone is a fully 
modular instrument with 14 fixed feature/func- 
tion and 16 flexible buttons that can be flexibly 
assigned as either CO/PBX/Centrex lines, Sta- 
tion DSS, or feature/function buttons for the 
2448EX. This set also features an integrated 
48 character LCD display, and integrated 
speakerphone, call announce with handsfree 
intercom, two (2) volume controls, an intercom 
mode select switch, and long life LED%. 
D. DSSIDLS Consoles 
The station port used for a DSS/ DLS Console 
can be assigned as a Direct Station Select or 
Direct Line Select depending on customer 
need. The bottom two rows of buttons on the 
DS!S/DLS Console (Refer to Figure 400-2) con- 
tain 6-8 flexible buttons (depending on MAP 
chosen) which can be assigned by the station 
user in the same manner and functions as the 
flexible buttons on the keyset. E. Phone Box 
The Phone Box (Refer to Figure 400-2) allows 
Handsfree conversations for locations that do 
not need dialing privileges. Phone Boxes may 
be substituted for Key Telephones on a one-for- 
one basis. 
400.5 SYSTEM CAPACITY 
The Basic KSU is housed in a wall-mountable cabi- 
net that contains the backplane, two prewired con- 
nectors for Power Failure Transfer units, station and 
CO line boards, DC/DC Converter and an Applica- 
tions board. This Basic KSU has a capacity of 24 
CO lines and 48 Key Telephones and/ or Phone 
Boxes. DSS/DLS’s can be installed in place of any 
Key Telephone. Standard single line telephones 
(2500 type) can be installed by exchanging key 
station interface boards. Eight single line tele- 
phones can replace eight Key Telephones for each 
board exchanged. An ON/OFF switch is located on 
the left side of the Basic KSU.
