Installation
1. Set the DIP switches to match Figure 
9-23. The DIP switches are preset from 
the factory for the USA and Canada. 
Refer to Table 9-1 on Page 9-4 for other 
country settings.
2. If required to achieve maximum 
distance (greater than 1000 ft.), install a 
two-pair house cable (or external 
power).
Programming
Program 03: Specify Code 61 to indicate a 
station line PDKU2.
Program 27: Adjusts initial off-hook volume 
level for digital telephone handsets.
Program 38: Specify Code 21.
Program 39: Specify button 01 as a [PDN]. 
Important!Do not program CO lines or 
secondary line appearances onto 
button 01 or in any other position. 
Since the system assigns CO lines 
01~17 by default, be sure to 
remove any CO line appearances by programming them as Station Speed Dial buttons 
(code 

).
NoteIf the 6SHHGLDO6HOHFW button is removed, the
 key becomes the 6SHHGLDO
6HOHFW
 button. While on an outside call, the user must press 
 then to activate the 
 
and
 DTMF tones for the duration of the call.
Program 92-5: Initializes initial ringing, speaker, and muted ring volume levels of digital 
telephones.
Also, refer to the Numerical Programming Listing in the Strata DK Programming Manual  for 
other station-related programs.

This chapter provides connection procedures for optional peripheral equipment to Strata DK 
Systems. Information in this chapter applies to all systems, unless stated otherwise in text.
Instructions include hardware requirements, PCB configuration, interconnection/wiring 
requirements, and programming considerations. Peripheral equipment is connected to system 
PCBs. See Chapter 7 – DK40i/DK424 Universal Slot PCBs installation and configuration 
information and the appropriate installation section.
Power Failure Options
In the event of a power failure, Strata DK uses these options:
Reserve Power
For information on the Reserve Power Option, see: 
©Chapter 1 – DK14 Installation
©Chapter 3 – DK40i Installation
©Chapter 5 – DK424 Installation
DK14/DK40i Single-line Power Failure Emergency Transfer
DK14 and DK40i have a built-in single-line Power Failure Emergency Transfer (requires loop 
start lines). See Chapter 1 – DK14 Installation and Chapter 3 – DK40i Installation for detailed 
information.
DK40i/DK424 Power Failure Transfer Unit
An optional Power Failure Transfer Unit (DPFT) can be installed that automatically connects up to 
eight selected CO lines directly to designated standard telephones in the event of a power failure. 
The DPFT enables normal operation of the selected CO lines and standard telephones when the 
system is in service. When power is restored, each telephone is independently reconnected to 
system standard telephone circuit ports after it is finished with its direct CO line call. The DPFT is 
normally installed on the MDF.
Figure 10-1 provides a circuit diagram of the DPFT.

To install the MOH option
1. Connect the external music source to the DK14 or DK40i KSU, or DK424 RCTU, RCA jack 
(see Figure 10-1).
2. Rotate the DK14 KSU, DK40i KSU or RCTU volume control (VR1) to adjust MOH volume: 
clockwise increases volume; counterclockwise decreases volume. Listen to the CO line on-
hold when setting MOH to the proper volume.
3. If MOH relay control is required, access Program 77-1. Set LED 05 to ON to configure the 
MOH/Night Transfer Control relay for the MOH function. This feature requires the 
installation of a DK14 KSU, DK40i KSU, or PIOU, PIOUS, or PEPU PCB.
4. If using the MOH control feature with a PIOU or PEPU, set PIOU or PEPU jumper plug P11 
to the MAKE or BREAK position as required:
©MAKE (M) – Shorts the normally open contacts (pins 9 and 34) when MOH is activated.
©BREAK (B) – Opens the normally closed contacts (pins 9 and 34) when MOH is 
activated.
...or
If using the MOH control feature with a PIOUS, solder PIOUS jumper W2 to the MAKE or 
BREAK position as required:
©MAKE (M) – Shorts the normally open contacts (NHT and NHR) when any CO line is in 
the hold condition.
©BREAK (B) – Opens the normally closed contacts (NHT and NHR) when any CO line is 
in the hold condition.
5. MOH (CO line or intercom hold) is applied from the RCTU through the KSU’s backplane to 
DID lines, tie lines, CO lines, electronic, digital, and standard telephones on hold.
6. MOH is also applied through the DK14 KSU, DK40i KSU, RCTU, Page/BGM control to 
provide BGM to electronic/digital telephone speakers and external page.

BGM Options
The BGM options allow music to play over optional external speakers (external page system) and/
or digital and electronic telephone speakers. BGM can be configured in three ways:
Configuration A – One Music Source
This configuration enables BGM and MOH to share the same music source (see Figure 10-3). 
With this configuration, the MOH/BGM music source is connected to the RCA jack on the DK14 
KSU, DK40i KSU or RCTU PCB. The music source is sent to CO lines/stations on hold, to 
electronic/digital telephone speakers, and to the external page system via the PIOU, PIOUS, or 
PEPU optional PCBs. Station Port 000 must dial 
 to send MOH over BGM and to 
disable the option.
Figure 10-3 MOH/BGM Music Source Configuration A
NoteTelephone users can turn on BGM at their station by pressing the 7HO6HW0XVLF (%*0) 
button; or by pressing [PDN] + 
 ( turns BGM OFF).
Configuration B – Alternate Background Music Source
This configuration enables the MOH source to be connected to the MOH RCA jack of the DK14 
KSU, DK40i KSU or RCTU, (as in Configuration A) and a separate BGM source to be connected 
to a PEKU (circuit 3), PESU (circuit 8)
...or
KSTU2, QSTU2, RSTU, RSTU2, RDSU, or PSTU (circuit 2) PCB (see Figures 10-4 and 10-5). 
With this configuration, the MOH source is sent only to CO lines/stations on hold, while the BGM 
source is sent directly to electronic/digital telephone speakers and to the external page system via 
the PIOU, PIOUS, PEPU or DK14 and DK40i BGM 600 ohm RCA jack.

Configuration C – Three Music Sources
This configuration enables the MOH source to be connected to the RCA jack of the DK40i KSU or 
DK424 RCTU (as in Configuration A). The digital or electronic telephone BGM source is 
connected to a PEKU, PESU, KSTU2, RSTU, RSTU2, RDSU or PSTU PCB (as in Configuration 
B), and a separate BGM source is sent to the external page speakers via the PIOU PCB (see Figure 
10-6). This option is not available on DK14.
When a separate BGM source is connected to the PIOU, two customer-supplied amplifiers are 
required to drive the external speakers.One amplifier drives the speakers for BGM when page is 
idle and the other amplifier drives the speakers during page. The PIOU switches BGM or page to 
the external speakers via zone relays. (The PIOUS and PEPU do not provide zone relays; therefore 
Configuration C is not possible with these PCBs.)
