							500.7 SPD 1428 & SPD 2856 TERMINALS 
A. Digital Terminal Installation: 
The Digital Terminals are interfaced with the SPD 
1428 KSU motherboard and have eight (8) circuits. 
Each of the eight (8) circuits are interfaced from the 
Ji 1 connector on the KSU motherboard to the MDF. 
The Digital Terminals are interfaced with the SPD 
2856 CKB boards which each have eight (8) circuits 
per board. Each CKB board interface is extended 
from the KSU to the MDF through the front edge 
connector on the CKB board. 
At the MDF are the terminated distribution cables 
that are run from each Key Telephone location. 
Each Key Telephone requires two-pair twisted cable 
wiring to connect the Digital Terminals to the System 
on a “home run” basis. The telephone end of 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 Figures 500-l 
and 500-5. 
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 
frame to the station wall jack should not exceed 1000 
feet. It is recommended that the station cable con- 
tain 4 pairs of wires. Refer to Figure 500-15. 
Station cable is connected to the MDF at one end, 
and a modular connecting blockat the other end. The 
modular line cord of the telephone is then plugged 
into the connecting 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 and control signals) from the sys- 
tem to the telephone, and two wires are used by the 
telephone to send digital information to the system. 
All 4 wires are necessary for the telephone to func- 
tion. Each telephone connected to a station port has 
two digital channels. The primary channel is used 
for voice communications only. The secondary 
channel is used to provide a secondary path for data 
switching applications (future). 
The installer should exercise caution when connect- 
ing a Key Telephone while System power is on. Each 
key station circuit is overload protected by internal 
circuitry on the CKB card, however the proper polar- 
ity of the wired connections must be maintained for 
proper operation. 
The Single Line Telephone Adapter (OPXI), and 
Digital DSS/DLS Console are all considered to be 
telephones by the system. These interfaces are all 
wired to digital key station ports the same as a digital 
telephone. B. Digital DSS/DLS Installation: 
The Digital DSS/DLS is assigned to operate with a 
Digital Terminal. Up to 3 units can be assigned to a 
station. There is no limit to the number of units that 
can be installed in a system, but each unit uses a 
Digital Terminal interface circuit and this reduces 
station capacity on a one-per-one basis. 
A two-pair twisted cable is required for connecting 
the DSS/DLS unit to the MDF. The cable should be 
placed from the DSS/DLS to the MDF in a “home 
run” manner. The DSS/DLS end of the cable is 
terminated on a three-pair modular jack and the MDF 
is “punched down” on a terminal block for cross 
connection to the appropriate station cable. Refer to 
Figure 500-l 5. 
Since the system supplies power to the DSSIDLS, 
no transformer or external power device is required.

C. Wall Mounting the Telephone 
All connections to the Digital Terminal are fully 
modular. To wall mount the Digital Terminal, it is 
necessary to use the Wall Mount bracket that comes 
with each Digital Terminal and one standard-type 
jack assembly designed for normal wall hanging 
applications. 
a. 
b. 
c. 
d. 
e. Unplug the line cord from the phone. This line 
cord will be re-used and should be retained. 
Using a screw driver, remove the plastic num- 
ber retainer by inserting the screw driver under- 
neath the middle of the retainer and prying 
upwards. Remove the screw and the handset 
tab. Be careful to position 
the tab so that the 
protrusion faces the hookswitch. This will allow 
the handset to remain secure when the tele- 
phone is on the wall. Replace the screw and 
snap the number retainer 
back into place. 
Reverse the back plate on the telephone for 
wall mounting. 
Line up the hooks at the bottom of the bracket 
so that they engage with the slots cut in the 
bottom of the telephone base. Tilt the telephone 
back and lock the telephone into the hooks at 
the top of the bracket. The bracket will snap in 
place. 
Route the line cord from the wall jack and plug 
into the connector on the back of the telephone. 
Now match the two 
key hole slots on the base- 
plate with the lugs on the 630-A type jack. Align 
the modular connector and slide telephone into 
place. Refer to Figure 500-l 6.

D. Single Line Telephone Installation: (future) 
Single Line Telephones (SLT’s) can be exchanged 
for Digital Terminals on an one-for-one basis. The 
following items are required for a system installing 
SLTs: E. SLT Adapter / Off-Premise Extension Mod- 
ule 
l 4x8 CO/SLT Interface Board (CSB) 
l DTMF Receiver Module (RM) 
The CSB plugged into any designated CKB card slot. 
Each CSB board supports eight telephones (stand- 
ard DTMF Single Line Telephones and message 
waiting DTMF SLT’s). A 48V Power Supply Unit 
must be installed in the system to provide power for 
ringing and message waiting for SLT’s. Refer to 
Figure 500-17. The DTMF Receiver Module should 
be installed for each CSB installed. The DTMF 
Receiver Module (RM) installs onto either a 4x8 
CO/Station Interface cards or 4x8 CO/SLT Interface 
cards and provides 1 DTMF receiver. DTMF receiv- 
ers can be added to the system to support Single 
Line Telephones. If SLT traffic is heavy or a Voice 
Mail system is being installed, it is recommended 
that additional DTMF Receiver Modules be installed 
in the system. This external module provides the interface for one 
long loop (OPX) single line telephone (2500 type) 
extension. This module requires a separately pro- 
vided -48 VDC power supply to provide the neces- 
sary current for long loop applications and to support 
ring generation. This module is wired to and uses a 
key station port from any digital key terminal station 
port on any card plugged into the system. The OPX 
card meets the requirements of the FCC for connec- 
tion to the telephone (Telco) network. Telephones 
must be DTMF only (2500 type). 
This module also provides for one Power Fail circuit 
in the event of an AC power failure. 
Buttons and LED’s: 
An LED located on the back of the unit indicates 
correct connection and will light when the SLT station 
is taken off-hook. 
Connections: 
Each SLT requires one-pair cable. The cable should 
be placed from the telephone location to the MDF in 
a “home run” manner. The telephone end of the 
cable run should be terminated in a modular jack. 
Refer to Figures 500-l and/or 500-5. The MDF end 
should be “punched down” on a terminal block for 
cross connection to the appropriate station cable. 
Refer to Table 500-5 for SLT wiring 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 
connection to the KSU and power supply. The two 
wire cable connects to a 48V dc power supply / ring 
generator. The Modular jack marked KSU is con- 
nected to a KSU Digital terminal station port. This 
connection requires all fourwires 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 SLT modular connecter for 
Power fail operation. 
Cable Loop Limits: 
The maximum loop limit from the KSU to the SLA 
(OPX) adapter is 1000 feet. 
The maximum loop limit from the SLA (OPX) adapter 
to the connected SLT or device is 1400 ohms not 
including the telephone or device.

500.8 POWER FAILURE TRANSFER 
A. Relay / Sensor Interface Module 
The Relay Sensor Interface Module connects to the 
system using one digital station port and provides 
three relay activated contacts and three sensing 
circuits. The relays provide for applications such as 
Loud Bell Control contacts, CO Line control contacts, 
RAN Start contacts, Page Relays, Power Fail con- 
tact and additional applications as software will per- 
mit. The sensing circuits will provide for such 
applications as Alarm signaling input, RAN Stop (end 
of message) and other applications as developed 
and allowed by software. power fail transfer. Refer to Tables 500-6 and 500-7 
for pin-outs of each of the connectors. _ 
The PFTU is connected to the KSU via the modular 
connector on the side of the unit. This is connected 
in series to a customer provided 12 dc supply. and 
to a multi use relay programmed as a power failure 
relay. 
4 
Connections: 
All connections to the Relay Sensor Module are 
made on the back of the unit. Two terminal strips 
with screw terminals each provide connection to the 
ancillary devices for relay control or sensing moni- 
toring. The Modular jack marked KSU is connected 
to a KSU Digital terminal station port. This connec- 
tion requires all four wires and wires the same as a 
key station. Refer to Figure 500-18 for wiring infor- 
mation. 
An external power source may be required to drive 
equipment connected to the relay contacts. The 
contacts are rated at 24Vdc max at 1 amp. 
Cable Loop Limits: 
The maximum loop limit from the KSU to the relay 
Sensor Module is 1000 feet. 
6. Starplus Power Failure Transfer Unit 
(Pm0 
This unit provides the relay transfer circuits for up to 
12 CO lines in the event of a power or processor 
failure. The unit is housed in its own enclosure and 
mounts external to the KSU. Activation of the PFT 
relays is controlled by a multi-use relay on any one 
of the CO / Station Interface boards that is pro- 
grammed for PFT. A customer provided 12 volt DC 
power supply is required to operate the unit. There 
is a manual switch that activates the PFTM for testing 
purposes. 
With loss of power to the system or a failure of 
system processing, the PFRJ will automatically con- 
nect up to twelve CO lines to prewired 500/2500 type 
telephones. When power is restored, the PFTU will 
automatically restore the CO trunks and stations to 
normal operation. These SLT stations do not have 
to be used for intercom. but can be if so desired. 
Wirina I Pinouts I Connections 
The PFTU has two 50-pin male amphenol connec- 
tors labeled CONNl and CONN2 located on the front 
of the unit. Each connector wires 8 CO lines for
