Printed Circuit Board (PCB) Installation

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:
o A maximum of two QCDU2s: each one provides one CO line circuit and two digital telephone
circuits.
o A QSTU2 which provides two standard telephone circuits (ports).
A QRCU2 which provides three circuits to receive DTMF tones (required for DISA and
o
devices connected to QSTU2s), and three circuits to detect busy tone (required for the ABR
feature).
o 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.
o 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

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 12 – 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.
