Printed Circuit Board (PCB) Installation
This section provides procedures for installation of Strata DK14 system optional printed circuit 
boards (PCBs) into the KSU. This includes installation instructions, optional configuration 
information, and wiring and programming considerations for each PCB.
Be sure the ground has been checked. (See “AC Power and Grounding Requirements” on Page 
1-3.)
PCB Installation Considerations
The Strata DK14 KSU comes standard with four digital telephone circuits (ports) and two CO line 
circuits. These circuits, along with the common control unit, are built into the motherboard.
KSU Option PCBs
The DK14 KSU can support up to four optional PCBs, including: 
©A maximum of two QCDU2s: each one provides one CO line circuit and two digital telephone 
circuits.
©A QSTU2 which provides two standard telephone circuits (ports).
©A QRCU2 which provides three circuits to receive DTMF tones (required for DISA and 
devices connected to QSTU2s), and three circuits to detect busy tone (required for the ABR 
feature).
©A WSIU which provides a port for either a Station Message Detail Recording (SMDR) device 
or a maintenance terminal or modem, or Caller ID interface.
©The KSU does not come from the factory with any option PCBs installed. Each of the option 
PCBs must be installed in specific locations. (See Figure 1-9.)
PCB Option Considerations
PCBs may be configured for a variety of hardware and software options. Hardware options are 
defined as either internal (generally related to optional PCB subassemblies) or external (related to 
connection of peripheral equipment such as background music, voice mail, etc.). Hardware and 
software options for each PCB are identified in the individual PCB installation procedures in this 
chapter.
PCB Hardware Options. Each PCB must be configured for the applicable hardware options prior 
to installation of the PCB. Configuration instructions for internal hardware options are provided in 
the individual PCB installation procedures in this chapter. Configuration instructions for external 
hardware options are provided in Chapter 10 – Peripheral Installation.
PCB Software Options. After installation of the PCBs in the KSU, configure the PCBs for 
software options through programming. A programming overview for each PCB is provided in the 
individual PCB installation procedures in this chapter. Refer to the Strata DK Programming 
Manual for detailed instructions.
PCB Installation/Power Supply Considerations
Whenever removing or installing PCBs it is recommended that the power supply be OFF.

Built-in CO Line, Digital, Telephone, and Other Circuits
1-12Strata DK I&M    5/99
Built-in CO Line, Digital, Telephone, and Other Circuits
The KSU comes standard with two CO lines and four digital telephone circuits already installed on 
the motherboard (WMAU). See Figure 1-4 for an illustration of the WMAU.
Built-in CO Line Circuits
The two standard loop start CO line circuits are integrated into the KSU motherboard WMAU and 
are identical to the QCDU2 CO line circuits. 
CO lines that receive Caller ID must be cross-connected to the TC-1041 (MLX-41) Caller ID 
interface box (See Page 1-19 for address). See Figure 1-18 for wiring. 
Built-in Digital Telephone Circuits
The four digital telephone circuits that come standard with the system are integrated into the 
motherboard in the KSU. These circuits are identical to the digital circuits found on the QCDU2. 
The motherboard does not have to be configured for the digital circuits to operate.
KSU Motherboard CO Line/Digital Station Circuit Wiring
See Figures 1-15~1-17 for details.
Power Failure Telephone Installation
1. Remove the RJ11 cover (Figure 1-11) from the PFT jack and store the jack cover.
2. Connect the power failure telephone (500/2500-type standard telephone to the PFT jack. 
Figure 1-17 shows the DK14 MDF to CO Line Wiring.
Music-On-Hold (MOH)/Background Music (BGM) Source Connection
Connect the MOH/BGM source to the MOH RCA jack (Figures 1-9 and 1-16) in accordance with 
Music Source Configuration A in Chapter 10 – Peripheral Installation.
External Page Output Connection
Connect the external page system to the 600ohm PAGE RCA output jack (Figure 1-9) to an 
external amplifier in accordance with the External Page Installation guidelines in Chapter 10 – 
Peripheral Installation.

QCDU2 Configuration
The QCDU2 may have to be configured to control excessive loudness if the system is close to a 
CO or installed behind a PBX telephone system. It does not have to be configured for anything 
else. The decibel (db) PAD switch, SW101 controls the loudness by providing a 3 db signal level 
drop to, or from, the PBX or CO when set to the PAD position. The switch comes from the factory 
set at 0 (for no PAD) meaning no PAD loss.
QCDU2 Installation
A maximum of two QCDU2 PCBs can be installed in the KSU.
äTo install the QCDU2
1. If the system is located within one mile of the CO or PBX telephone system, set db PAD 
switch SW101 to the PAD position.
2. Make sure that the power supply switch is OFF.
3.Slide QCDU2’s front edge and FG wire under the System Frame Ground Bar; align and insert 
the QCDU2 connector J1 into the motherboard connector (J9 for CO3 first, J10 for CO4 
second). 
(See Figure 1-10)
 
Apply firm, even pressure to ensure proper 
mating of the connectors. Make sure the 
QCDU2’s connector edge next to the connector 
J1 snaps firmly into the standoffs on the KSU 
motherboard. (See Figure 1-4).
4. Connect the Frame Ground (FG) lead from the 
QCDU2 to the screw nearest the QCDU2 
located on the system Frame Ground bar. 
Remove the “knock-out” from the KSU cover 
CO3 or CO4 access slot, and store the “knock-
out” in the slots provided in the KSU base. (See 
Figure 1-11.)

Older Version(s):QSTU1A
NoteFor the system to recognize the Dual-Tone Multi-Frequency (DTMF) tones generated by 
standard telephones (or any other device connected to a QSTU2 port), a QRCU3 must be 
installed.
The QSTS2 PCB is factory-installed on the QSTU.
QSTU2 Configuration
The QSTU2 does not require configurations for the ring generator voltage level. Most standard 
telephones and two-wire devices require 190; however, some devices may experience ring-trip at 
190, and should be set at 130.
QSTU2 Installation
1. Make sure the power supply switch is OFF.
2. Align the QSTU2 connectors J1, J2, J3, and J4 to the motherboard connectors J11, J12, J13, 
and J14 respectively. Apply firm, even pressure to ensure proper mating of the connectors (see 
Figure 1-12).

QSTU2 Programming
The following parameters can be specified for the QSTU2:
Program 31: Used to configure all QSTU2 ports connected to voice mail (see Chapter 7 – DK40i/
DK424 Universal Slot PCBs for voice mail installation).
Program 10-2: Used to set standard telephone ringing option and separate BGM assignment.
NoteQSTU2 ports are fixed. They are assigned even if a QSTU2 is not installed.
QSTU2 Wiring
Refer to DK14 MDF to KSU Amphenol Wiring in Figure 1-16 for QSTU2 wiring.
The QSTU2 must be connected to a OL13A (or equivalent) type lines for off-premises stations. 
(300 ohms loop resistance max., including the telephone or other devices DC off hook resistance.)

Older Version(s):QRCU1/QRCU2
The QRCU3 must be installed to recognize Dual-Tone Multi-Frequency (DTMF) tones generated 
by a standard telephone (or any other device connected to a standard telephone circuit (QSTU2), 
and it is required for Direct Inward System Access (DISA) calls. The QRCU3 circuits are also 
used to detect busy tone for the Automatic Busy Redial (ABR) feature and must be installed to 
allow ABR to operate.
QRCU3 Configuration
The QRCU3 does not have to be configured for operation.
QRCU3 Installation
1. Make sure that the power supply switch is OFF.
2. Align and insert the QRCU3 connectors J1 and J2 (see Figure 1-13 into the motherboard 
connectors J15 and J16 respectively (note the component side placement in Figure 1-4). Apply 
firm, even pressure to ensure proper mating of connectors. Push down until the connectors 
lock together.
QRCU3 Programming
The following parameters can be specified:
Program 12: Set QRCU3 release time.
Program 15: Sets QRCU3 operation after CO line flash.

QRCU3 PCB.
äTo install the QKYS1 Key
1. Make sure that the DKSU14 power supply switch is OFF.
2. Install the QKYS1 into the QKYS1 connector on the QRCU2 PCB (see Figure 1-13).
3. The QKYS1 does not require Program 03 assignments.
