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

OPX circuits
(extensions

RS-232C
Module (RSM]
This RS-232C
Module
(RSM) mounts
on
the Application

This con-
nector
may be used to output

unit (SLUI
Used to expand
the MMF
receivers
and

in the System
to support

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.
