Digital Key Telephone System
F.Single Line Board (SL12)The Single Line Telephone board (SL12)
provides the interface for 12 2500-type sin-gle line telephones. This board can be
plugged into any designated station slot. It
is recommended that the Tri-Output PowerSupply be used with this card to provide
the 
9OV ac and -48V dc voltages.
Only one Ring Generator is required per
system. One Tri-Output Power Supply willaccommodate two SL12 boards. When an
SL12 board is installed, it is recommended
that the LWM4 DTMF Receiver Module beinstalled at the same time. If 3 or more SL12
boards are installed in the system. at least
1 DTM4 should be installed. However, rwmore than 3 SL12 boards with DTM4receiuers on them can be installed in thesgstem.Message Waiting capability comes in-
stalled on the Single Line Telephone Board(SL12). This circuitry provides message
waiting lamps to single line telephones
equipped with message waiting lamps andsupports up to 12 Single Line Telephone
Message Waiting lamps at 9OV dc typically
across tip and ring.
LEDs h Indicators
The board contains three LEDs to indicatethe presence of 
+5V dc, - 5V dc and -48V
dc. The LEDs are located on the top portionof the board.
Line/Station Interfaces:
The board has one female 50-pin amphenol
connector on the front edge. This interfacesthe circuits on the board to the MDF. The
board has one two- conductor molex con-
nector to provide an input for 9OV ac ring.A second two-conductor molex connector
interfaces -48V dc to the card. Each SL12
installed in the system must have both 9OVac and -48V dc applied to it via these
connectors. The card also provides proper
fusing or protection to comply with the
requirements of UL 1459 Second Edition
and CSA C22.2 No. 225 standards.
These single line telephones can be
equipped with a standard Message WaitingLamp 
(90VT & R) that operate on the “tip”
and “ring” leads. Additionally each circuit
provides a loop interrupt of 
7OOms dura-
tion. This is the duration of loop interruptprovided to a single line port if loop inter-
rupt is detected on a CO line that the single
line port was connected to. Also provided ifa station calls an SLT and hangs up.The
card will support single line telephones upto 2000 feet from the Basic KSU cabinet.
Refer to Table 200-4 Loop Limits for addi-
tional wiring information. On-premise sin-gle line telephones should present a load
to the port totaling a maximum ringer
equivalence of 2.5.Figure 500-10 Single Line Telephone Board

Digital Key Telephone System
500.7DIGITAL TERMINALS
A. Digital Terminal Installation:
The Digital 
Termina$s
are interfaced withthe infinite DVX
Key Station Board
(KT12) which has 12 circuits per board.
Each 12-circuit Key Station Board inter-
face is extended from the Basic KSU to theMDF through the front edge connector on
the key Station Board.
At the MDF are the terminated distributioncables that are run from each key tele-
phone location. Each Key Telephone re-
quires two-pair twisted cable wiring to
connect the digital terminals to the system
on a “home run” basis. The telephone endof the cable is terminated on a modular
jack and the MDF end of the cable should
terminate on a punchdown block making
up the MDF. Refer to Figure 500-2 Basic
KSU Equipment Cabinet.Telephones are connected to the station
interfaces via industry-standard twisted,
2-pair, 22 or 24 gauge wire. The station
cable run from the main distribution frameto the station wall jack should not exceed
1000 feet. Refer to Figure 
500- 13 Digital
Terminal Modular Block Wiring.Station cable is connected to the MDF at
one end, and a modular connecting block
at the other end. The modular line cord of
the telephone is then plugged into the con-
necting block.
Only one station may be connected to a port.It is NOT possible to bridge station ports.
The system communicates with each
phone using 4 wires. Two of the wires are
used to send digital information (voice andcontrol signals) from the system to the
telephone, and two wires are used by the
stelephone to send digital information to thesystem. All 4 wires are necessary for the
telephone to function. Each telephone con-nected to a station port has two digital
channels. The primary channel is used for
voice communications only. The secondarychannel is used to provide a secondary
path for data switching applications (fu-
ture) .
The installer should exercise caution when
connecting a digital terminal while systempower is on. Each digital terminal station
circuit is overload protected by internal
circuitry on the 12-circuit Key Station
Board (KT12) or 12-circuit Single Line Tele-phone Board 
(SL12), however the properpolarity of the wired connections must be
maintained for proper operation.
The standard Single Line Telephone, Sin-gle Line Telephone Adapter 
(OPX), and
Digital DSS Console are all considered to
be telephones by the system. These inter-faces are all wired to digital key station
ports the same as a digital telephone.
B.Digital DSS Console Installation:
The Digital DSS/DLS Console is assignedto operate with a digital terminal. Up to
three 
DSS/DLS Console units can be as-
signed to any one station. There are a maxi-
mum of 72 
DSS/DLS Consoles $at can beinstalled in the infinite DVX
System.
Each unit uses a digital terminal interfacecircuit and reduces station capacity on a
one-per-one basis.A two-pair twisted cable is required for
connecting the 
DSS/DLS Console unit to
the MDF. The cable should be run from the
DSS/DLS Console to the MDF in a “home
run” manner. The 
DSS/DLS Console end
of the cable is terminated on a three-pair
modular jack and the MDF is “punched
down” on a terminal block for cross con-
nection to the appropriate station cable.
Refer to Figure 500-13 Digital Terminal
Modular Block Wiring.
Since the system supplies power to the
DSS/DLS Console, no transformer or ex-
ternal power device is required.
C.Wall Mounting the 33-Button Digital
Terminal
To wall mount the infinite Digital Terminal,it is necessary to use the 33-Button Wall
Mount bracket and one standard-type jackassembly designed for normal wall hang-
ing 
applications.Refer to Figure 500-14
Digital Terminal Wall Mounting.1. Unplug the line cord from the phone. A
4-foot line cord is provided with the wall
bracket.2. Line up the hooks at the bottom of the
bracket so that they engage with the slotscut in the bottom of the telephone base.
Tilt the telephone back and lock the tele-phone into the hooks at the top of the
bracket. The bracket will snap in place.
3.Route the line cord from the wall jack and
plug into the connector on the back of thetelephone. Now match the two key hole
slots on the base plate with the lugs on the630-A type jack. Align the modular con-
nector and slide telephone into place.

E.Single Line Telephone InstallationSingle Line Telephones 
(SLTs) can be ex-
changed for digital terminals on a one-for-one basis with an OPX box.
The Single Line Telephone Board (SL12)
can be plugged into any designated card
slot. Each Single Line Telephone board
supports 12 standard single line tele-
phones (standard DTMF Single Line Tele-
phones and message waiting DTMF 
SLTs).It is recommended that the Tri-Output
Power Supply be used with this card to
provide the 
9OV ac and -48V dc voltages.
Only one Ring Generator is required persystem. One !7W-Output Pourer SuppZg w3.Zsaccommodate two SL12 boards. Whim anSL12 board is insta&x& it 3s recommended
that the DTM4 DTMF Receiver Module be
installed ut the same time. Zf 3 or mane SL12
hoards un? &&a&d irr the system, at least1 -4 shouM be installed. Hourever, no
more than 3 SL12 boards with DTM4receioers on them can be installed in the
system.
The DTMF Receiver Module (DTM4) may beinstalled on each Single Line Telephone
Board installed. The DTMF Receiver Mod-
ule (DTM4) installs onto a Single Line Tele-phone Board 
(SL12) and provides 4 DTMF
receivers. DTMF receivers can be added to
the system to support Single Line Tele-
phones. If SLT traffic is heavy or a Voice
Mail system is being installed, it is recom-mended that additional DTMF Receiver
Modules be installed in the system.
Each SLT requires one-pair cable. The ca-ble should be placed from the telephone
location to the MDF in a “home run” man-ner. The telephone end of the cable run
should be terminated in a modular jack.
Refer to Figure 500-2 Basic KSU
Equipment Cabinet. The MDF end should
be “punched down” on a terminal block for
cross connection to the appropriate stationcable. Refer to Figure 500-13 Digital
Terminal Modular Block Wiring for SLT
wiring connections.
F.SLT Adapter / Off-Premise Extension
Module (OPX)This external 
modu!le provides the inter-
face for one long loop 
(OPX) single line
telephone (2500 type) extension. This mod-
ule requires a separately provided 
-48V dc
power supply to provide the necessary cur-rent for long loop applications and to sup-
port ring generation. This module is wired
to and interfaces with a digital key terminal
port on the 
in.nite DVX I’ system. The OPX
box meets the requirements of the FCC forconnection to the telephone 
(Telco) net-
work. Telephones must be DTMF only
(2500 type). Refer to Figure 500-15 
Off-Premise Extension 
(OPX) Module

Power Fail circuit in the event of an AC
power failure and contains its own DTMF
receiver.Buttons and 
LEDs:An LED located on the back of the unit
indicates correct connection and will light
when the SLT station is taken off-hook.Connections:
All connections to the SLA 
(OPX) adapter
are made on the back of the unit. Two
modular jacks and a two-wire cable are
located on the back of the unit for comrec-
tion to the KSU and power supply. The twowire cable connects to a 
48V dc power
supply. The modular jack marked KSU is
connected to a KSU Digital terminal stationport. This connection requires all four
wires and wires the same as a key station.
The modular jack marked OPX is wired to
the SLT station (2500 type), OPX circuit or
SLT device. Additionally, a CO line may be
wired to the second pair of the 
SLTmodular
connector for Power fail operation.Issue 1, February 1994
