Strata DK141
This chapter provides an overview of the Strata DK14 System and its capacities.
The Strata DK14 Base Key Service Unit (KSU) is a 
compact system that provides many of the features offered 
by much larger systems. The Strata DK14 KSU is designed 
for convenient wall-mounting and occupies very little space 
(see Figure 1 and Ta b l e  1). 
At maximum configuration, the Strata DK14 provides up to 
10 station ports, that can be used for up to 8 digital 
telephones (including the cordless telephone), up to four 
Central Office (CO) lines can be accommodated, and two 
standard telephone devices.
The Strata DK14 can be upgraded with these optional 
peripherals:
©Music-on-hold (MOH) source
©Background Music (BGM) source
©Night bell
©Amplifier/speaker for external page
Also, any two of the following optional RS-232 interfaces 
can be added as needed:
©Caller ID (CLID)
©Station Message Detail Reporting (SMDR)
©Simplified Message Desk Interface (SMDI) for Voice Mail
©DKAdmin (TTY) Interface

KSU Architecture
The Strata DK14 KSU contains the main processor, operating software, circuitry and the following 
components (see Figure 2).
Figure 2 KSU Interior
Digital Telephone/Central Office (CO) Line Circuits
The main PCB (WMAU) has four integrated circuits that can connect to digital corded and/or 
cordless telephones, stand-alone data interface units (PDIU-DSs), and digital door phone/lock 
control units (DDCB). Each of the digital telephones can support a PC Data Interface Unit (RPCI-
DI) or up to two Add-on Modules (DADMs). It does not support a DDSS console.
Two circuits for loop start CO lines are built into the main PCB. Each line can be programmed for 
Dual-tone Multi-frequency (DTMF) or dial pulse signaling. It includes a switch to control 
potential excess volume from a nearby private branch exchange (PBX) or CO. Built-in gas tubes 
help protect each circuit from lightning. Each line supports Caller ID when optional equipment is 
added.

Optional Printed Circuit Boards
Central Office Line/Digital Telephone Interface Unit (QCDU2)
The QCDU2 provides one loop start CO line circuit and two digital telephone circuits. It interfaces 
with digital corded and/or cordless telephones, RPCI-DIs, ADMs connected to the corded 
telephones and PDIU-DSs, and door phones. The DK14 supports up to six door phones. It does not 
support a DDSS console. Up to two QCDU2 PCBs can be added to the DK14. Each line supports 
Caller ID when optional equipment is added.
Standard Telephone Interface Unit (QSTU2)
The QSTU2 provides two standard telephone circuits for two-wire devices such as standard 
telephones, Auto Attendant devices, alternate BGM source connection, voice mail machines, and 
facsimile machines.
DTMF Receiver/ABR Tone Detector Unit (QRCU3)
The QRCU3 enables the Strata DK14 to recognize Dual-Tone Multi-Frequency (DTMF) tones 
generated by a standard telephone or any other device connected to a QSTU3 standard telephone 
circuit. It is also required for Direct Inward System Access (DISA) calls and built-in Auto 
Attendant. The QRCU3 enables busy tone detection for Automatic Busy Redial.
Auto Attendant Feature Key (QKYS1) 
The QKYS1 plugs into the QRCU3 option PCB to support built-in Auto Attendant.
Serial Interface Board (WSIU1)
The WSIU1 provides two serial interface ports for up to two of the following devices:
©Caller ID interface box
©SMDR Call Accounting device
©SMDI Voice Mail Interface
©PC with DKAdmin or external modem

Power Supply
4Strata DK General Description     5/99
Power Supply
The power supply generates +5VDC and +24VDC for the entire system. Ta b l e  2 for a summary of 
electrical/environmental characteristics.
Table 2 Summary of Electrical/Environmental Characteristics
Reserve Power
One or two optional Reserve Power Battery and Chargers (HPFBs) can be connected to the Strata 
DK14 power supply to maintain normal operation during a power failure. The estimated battery 
time for one or two HPFBs is shown below.
Notes
lReserve power time varies with system call traffic.
lAC power must be available when HPFB is first installed.
lHPFB recharge time is 48 hours per HPFB.
Power Failure Interface
The Strata DK14 KSU provides an interface for a dedicated backup standard telephone during an 
AC input power failure. If the system AC input power fails, the backup telephone will 
automatically connect to the CO1 line. This feature is independent of the HPFB.

Music-on-Hold (MOH) Interface
Customers can connect their own MOH source to this interface. The source can also feed external 
page speakers and telephone speakers with Background Music (BGM).
Paging Interface
This 600-ohm interface can support a Toshiba External Speaker (HESB) or a customer-supplied 
amplifier and speaker for Paging, Night Ringing over Page, and BGM applications.
Flexible Relay Contacts
A relay contact can be programmed to either mute BGM during a page announcement over 
external speakers, to operate a device—such as an answering machine or ringing bell—during the 
Night Mode, or to provide on-off control for a MOH source.
Maximum Line/Station Configurations
The maximum line and station configurations for DK14 are shown in Ta b l e  3.
