Central Oface Interface Board (COB) 
Provides the interface for eight central of- 
fke DTMF or Dial Pulse) loop start lines. 
The board can be removed or inserted with 
KSU power ON, however, the ‘Nor- 
mal/Service’ switch should be in the 
‘Sexvice’ mode before removing 
or insea- 
ing the board into the system. An in-use 
LED for each circuit and a switch to take 
the board out of setice are provided. 
The CO circuiti are equipped with pro- 
grammable current sensing circuitry that 
identifies distant end disconnect loop su- 
pervIsion, if provided by the Central Of&e. 
AmpliI3ed Central Office Ynterface 
Board (cm 
The Amplified Central Office Interface 
Board (COAI is an 
opUonai card that in- 
stalls in place of any standard COB board. 
The COA enhances audio levels and con- 
tains all other attributes of the COB. The 
COA is recommended for DISA and 
multi- 
line conference applications and should 
not be used in the System behind a PBX 
because of possible feedback When Ani- 
plified CO operation is desired, it is recom- 
mended that &CO ctrcuits in the system 
be equipped on COA Boards. 
Key Station Interface 
Board (XIB) 
Provides interface circuit.~~ for eight Key 
Telephones. The KIB will support any In- 
jnfte Enhanced or Executive Key Tele- 
phone set. ‘Ihe KXB board can be inserted 
or removed with the KSU power ON, how- 
ever, the ‘Nom&/Service” switch should 
be in the ‘SeIvice” mode before removing 
or insexting the board into the system. An 
in-use LED and a switch to take the card 
out of service are provided. A DSS/DIS or 
Phone Box can also be assigned to any one 
of the cfrcuits. The KIB circuits are pro- 
tected from mis-wiring and overcurrent. 
Key Station Interface Board with Off- 
Hook Voice AMounce (glB/OHVl 
The Key Statton Interface Board with Off- 
Hook Voice Announce (KIB/OHVJ provides 
interface circuitry for eight Electronic Key 
Telephones (Enhanced or Executive). in- 
cluding the capability for 081 Hook Voice 
Announce (requires an OHVA equipped

moved with the KSU power ON. A DSS or 
Phone BQX can be assigned to any one of 
the circuits. Used in placed of KIB board. 
E. Shqle Line Telephone Inter&e Board 
(SIB) 
The Single Line Telephone Interface Board 
provides interface for eight (8) -24 vdc 
single line (2500 type) telephones. Single 
Line Telephone Interfarx Boards (SIB’s) 
and Key Station Interface Boards 0UB’s) 
are interchangeable wlthin the system. 
Both standard MMF andmessage waiting 
(9OV’) DTMF single line telephones may be 
used. An SIB or an OPX Board is required 
when connecting to a Voice Mail System 
and In-Band Integration is desired. An 
Application Board (APL) and a Ring Gen- 
erator (RG) are required when fnsblung 
SIB’S. 
F. OfWrcmise Ertcnsions Board (OPXI 
The Single Line OPX Board provides four 
(4) 48 vdc FCC registered 2500-type sin- 
gle line interface ports. When an OPX is 
installed. the maximum number of sta- 
tions in the system is reduced by four. 
OPX station features are the same as SLT 
station features. The only exception is 
‘Receiving Message Waiting Indication’, 
which is not allowed. Thus. OPX stations 
cannot answer a message waiting indica- 
tion since they are incapable of receiving 
such an indication. All other feature op- 
eration is identical to that of on-premise 
SLT stations. 
Each OPX port requires an OL13C net- 
work circuit An FCC registered interface, 
such as RJ21X is required to connect to 
the public network. Only SLT devices ca- 
pable of sending true DTMF can be used 
on an OPX circuit provided by the system. 
When an OPX board is installed. four sta- 
tion ports are rendered unusable, reduc- 
ing the maximum number of stations in 
the system by four. For example, with an 
OPX board inserted into the second KIB 
card slot extensions 108 through 111 sup- 
port four OPX circuits (extensions 112 
through 115 are not usable)& Applica- 
tion Board (APL) and a Ring Generator 
(RG) are required when installing an 
OPX 
Board. 200.4

unsupervised conference and one external 
page zone as well as the drcuttxy for two 
MMF recehers and two MMF senders to 
support a small number of single line tele- 
phones. The APL has provisions for the 
addition of a Single Ltne DTMFRS Unit 
(SLU). used to support larger quantities of 
single-be telephones, and an RS232C 
Module (RsMj to add an 
additional F2S 
23242 port for outputting SMDR informa- 
tion only. This port cannot be used for 
pro- locally or remotely via a ter- 
minal. The APL also has a connection for 
Recorded Announcement (RAN) input and 
its control contacts. 
RS-232C 
Module (RSM] 
This RS-232C Module (RSM) mounts on 
the Application Board (APL) and provides 
a second RS-232C connector. This con- 
nector may be used to output SMDR data 
while the standard RS-232C (located on 
the CPB) is used for system printout or 
Remote AdministraUon. 
Single 
Line DTMF Receiver/Sender 
unit (SLUI 
Used to expand the MMF receivers and 
senders in the System to support single 
line telephones. The module is added to 
the APL board and contains four IYlMF 
receivers and one DTMF sender.

D. Power Failure Transfer Unit (PPT) 
There can be two Power Failure Ransfer 
Units installed in the Basic KSU, each 
providing automatic direct cut-through 
connection of six CO/PBX lines to six sln- 
gle 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 PFI’ in- 
stalled there is one set of Loud Bell Control 
wntacts provided. This unit can be re- 
moved or inserted with power on the KSU. 
There 
is a manua.l switch that activates the 
PFT for testing purposes.
