4.30 DSS/DDSS Console Hardware Configura- 
tion Notes 
A maximum of four DDSS consoles or four DSS 
consoles (or any combination up to four) is 
allowed per system with PCTU(1, 2, or 3) and 
three with PCTUS. 
DDSS consoles operate with PCTU3 only, while 
DSS consoles operate with PCTUI, 2, or 3 or 
PCTUS. 
DDSS consoles normally operate in conjunction 
with digital telephones. Each DDSS console is 
assigned to an associated digital telephone (on 
circuit 1 of the same PDKU), which in turn are 
referred to as a DDSS/attendant telephone. 
DSS consoles normally operate in conjunction 
with electronic telephones. Each DSS console is 
assigned to an associated electronic telephone 
(on circuit 1 of the same PEKU), which in turn are 
referred to as a DSS/attendant telephone. 
DDSS consoles will operate with electronic tele- 
phones and DSS consoles will operate with 
digital telephones. 
One PDKU PCB is required for each DDSS/ attendant telephone. 
One PEKU PCB is required for each DSS/atten- 
dant telephone. 
DDSS consoles are always connected to PDKU 
circuit 8, and the associated digital telephone is 
always connected to PDKU circuit 1 (for a total of 
two PDKU ports per DDSS console/attendant 
telephone). 
I 
DSS consoles are always connected to PEKU 
circuits 7 and 8, and the associated attendant 
telephone is always connected to PEKU circuit 1 
(for a total of three PEKU ports per DSS console/ 
attendant telephone). 
PDKWDDSS slots are identified and assigned in 
Program 03 with special PCB code 64 (refer to 
Figure 4-2). 
I 
PEKWDSS slots are identified and assigned in 
Program 03 with special PCB codes 23 or 24 
(refer to Figure 4-2). 
DSS consoles and attendant telephones are 
automatically assigned as DSSl/ATTl , DSS2/ 
ATT2, DSS3/ATT3, or DSS4/ATT4, starting with 
the lowest DSSPEKU slots and continuing, in 
consecutive order, to the highest DSSPEKU 
slot (this also applies to DDSS consoles and 
attendant telephones). 
Each DSS console is assigned to the attendant 
telephone connected to the same PEKU PCB 
supporting that DSS console; however, DSS 
consoles may be flexibly reassigned (in 
Program 
28) to any of the designated attendant tele- 
phones 
allowing a maximum of four DSS con- 
soles assigned to one attendant telephone (this 
also applies to digital telephones). 
DSS console buttons may be flexibly assigned 
(in 
Program 29) as CO line buttons, DSS (hot 
line) buttons, and speed dial buttons. 
4.40 Data Interface Unit (DIU) Configuration 
Notes 
l The integrated data interface unit (PDIU-DI) 
shares the same wire pair and PDKU station 
circuit with the digital telephone to which it is 
connected. The PDIU-DI requires a PCTU3 
control PCB. The PDIU-DI capacity is shown in 
Table 4-B. 
l The PDIU-DI is a DCE type device that normally 
connects to a personal computer serial commu-

1 GENERAL 
1 .OO This chapter provides the procedures neces- 
sary to install the DK KSUs. The chapter includes 
mounting considerations, grounding instructions, 
and instructions to test the power supply. Instruc- 
tions to remove and replace the power supply are 
also provided. 
2 KSU INSTALLATION 
2.00 The KSU may be either wall-mounted or 
table-top mounted. The following paragraphs 
provide procedures for both mounting options. 
2.01 To optimize airflow and ventilation: 
l Ensure that the installation site provides the 
minimum clearances specified in Installation 
Site Requirements, Section 200-096-203, 
Paragraph 3. 
l Do not block the ventilation holes at the rear 
and both sides of the KSU. 
2.10 Wall Mounting 
1) Install the three wall-mounting brackets (packed 
in the shipping carton with the KSU) on the rear 
of the KSU in both upper corners, and at the 
bottom center. Secure each bracket to the KSU 
with the back panel screws and the screws 
supplied with the brackets (see Figure 5-l). 
NOTE: 
The KSU back panel should not be removed. 
2) Mark the appropriate mounting screw locations 
on the wall by using Figure 5-1, or hold the KSU 
against the wall at the selected mounting lo- 
cation. Mark the positions of the holes in the flat 
part of each mounting bracket where they 
contact the wall. Mounting screws will be in- 
stalled at these locations. 
NOTE: 
Wall anchors are required for dry-wall sur- 
faces where studs do not align with the 
I mounting screw locations (see Figure 5-6). 
1 3) Install two 1.25-inch long panhead wood screws 
approximately half way into the wall at the 
upper mounting bracket locations.

WALL MOUNTING BRACKET INSTALLATION 
4) Hang the KSU from the top two mounting 
screws. 
5) Install a third 1.25-inch panhead wood screw I 
through the hole in the bottom mounting bracket. 
6) Tighten the three mounting screws firmly to 
secure the KSU to the wall. 
2.20 Table-top Mounting 
2.21 
Table-top mounting requires no special in- 
stallation procedures. However, it is suggested 
that the top wall-mounting brackets be installed to 
ensure adequate ventilation at all times. 
NOTE: 
Do not install the KSU directly on the floor. 
2.30 KSU AC Power and Ground 
2.31 
Ensure the system AC power and earth 
ground complies with the requirements listed in 
Installation Site Requirements, Section 200-096- 
203, prior to connecting the AC power plug. 
NOTE: 
TheACpowermustbe dedicated to the KSU. 
Do not use power/ground intended for an- 
other piece of equipment.

3 POWER SUPPLY TEST PROCEDURE 
3.00 Perform the power supply test procedure 
with all PCBs removed from the KSU. 
NOTE: 
Refer to System Description, Section 200-096- 
202, for illustrations and descriptions of KSU 
controls and indicators. 
1) Plug the AC power cable into the AC IN con- 
nector and to the AC wall socket. 
NOTE: 
The DK24 power cable is permanent/y con- 
nected to the power supply. 
2) Lightly press all power supply circuit breakers 
to ensure they have not accidentally opened 
during shipment. 
3) Set the power supply power switch to ON. 
Ensure that the power supply indicators light as 
follows: 
. DK24: 
l POWER indicator 
l -24V indicator 
l +5V indicator 
l -5V indicator 
l -24V, W V, (circuit breakers) 
. DK56:

. DK96: 
l POWER indicator 
l -5V indicator 
l +5V, indicator 
l +5V, indicator 
l -24V, W V,(circuit breakers) 
4) Using a multimeter (set to the appropriate range), 
measure the voltages at the pins of the DC OUT 
connector for DK56/DK96 or the PI backplane 
connector for DK24 as shown in Figures 5-2,5- 
3, or 5-4. Ensure that the voltages fall within the 
ranges specified. If a measured voltage falls 
outside of the acceptable range, remove the 
DC power plug from the power supply DC OUT 
connector (DK56/96) or PI backplane con- nectar (DK24) and measure again. If a meas- 
ured voltage is still unacceptable, rep!ace the 
power supply (refer to Paragraph 4). 
DC Voltage Range Specifications 
-24V: -26.3 - -27.0 
-5V: 
-4.5 - -5.5 
+5V: +4.5 - +5.5 
3.01 To test the power supply voltages with all 
circuit boards installed, install the circuit boards 
and then use the procedure in Paragraph 3.00 for 
the PPSU56/96, but follow the four steps below to 
test the PPSU24. 
1) Loosen the four screws holding the panel on 
the back of the KSU. 
2) Lift the panel up and pull it off of the KSU. 
3) On the lower left side of the backplane PCB 
(PMB-824), the test points for the various volt- 
ages are marked. Refer to Figure 5-5. 
4) Using the multimeter (set to the appropriate 
range), measure the voltages at the desig- 
nated test points. 
NOTE: 
The multimeter test probes must have sharp 
tips to penetrate solder mask on backplane 
PCB.
