telephone can dial internal stations or outgoing
central office (CO) lines directly, without going
through a receptionist or operator. A security code
can be assigned to prevent undesired access to
CO lines. DISA is available to any number of CO
lines.
Distinctive CO Line/Intercom Ringing: The incom-
ing Central Office (CO) line ringing pattern for both
digital and electronic telephones differs from the
intercom ringing pattern, thereby helping to indi-
cate the nature of a call. This feature is optional for
standard telephones.
Door Lock Control: Any telephone programmed with
a door unlock button can unlock a customer-sup-
plied electronic door lock just by pressing the but-
ton. The DK8 can support as many as two unlock
buttons, and the DK16 can support up to three.
Each unlock button can have an associated button
on designated digital and electronic telephones.
(The DDCB, PIOU, and PIOUS can each support
door lock control.)
Door Phones (MDFB): A door phone is frequently
mounted near a building entrance and is associat-
ed with a customer-provided door lock to help
screen visitors. However, a door phone can also
serve other functions: it can operate as a sound
monitor (station users can call the door phone and
listen to the surrounding area) or as a "hot line"
link. STRATA DK8 and DK16 can each support as
many as six door phones. Each door phone must
be connected to a door phone/lock control unit
(DDCB).
DTMF and Dial Pulse CO Line Compatible: DK8
and DK16 systems work with both Dual-tone Multi-
frequency (DTMF) and rotary dial pulse central
office (CO) lines.
DTMF Back Tone: DK8 and DK16 systems can be
programmed to allow or prevent Dual-tone Multi-
frequency (DTMF) tones from being returned to a
digital or electronic telephone when a user dials
over central office (CO) lines or sends digits to a
voice mail device.
DTMF Signal Time (80/160 milliseconds): The
duration of Dual-tone Multi-frequency (DTMF)
tones that are sent via Speed Dial to CO lines and
via automatic dialing to voice mail devices can be
18
set at 80 or 160 milliseconds. The time can be set
independently for CO line outdialing and for voice
mail automatic dialing.
Dual FCC Registration: DK8 and DK16 systems can
be configured for either key or hybrid operation.
Separate FCC registration numbers apply to each
operation type. The appropriate configuration for
an individual system depends on its function. For
more details, refer to General End User Informa-
tion, located in the front of this document.
External Page: Station users can make an
announcement over an external paging device
consisting of an amplifier and speaker, by entering
a brief access code. The paging device connects
directly to a 600 ohm output that is standard on the
DK8 and DK16 Key Service Unit. The 600 ohm
output is two-way and supports talk back amplifier
applications. For STRATA DK16, paging zone
options are also provided by the optional PIOU
PCB in the Expansion Unit.
External Page Zones (DK16 only): The system can
support as many as four external page zones. Sta-
tion users can access just one page zone or all of
them simultaneously simply by entering a brief
access code. Zones may be composed of cus-
tomer-supplied speaker(s) and amplifier(s) which
interface with a PIOU printed circuit board in the
Expansion Key Service Unit.
Flexible Button Assignment: Digital and electronic
telephones have 10 or 20 buttons which may be
flexibly programmed to access CO lines and fea-
tures.
Flexible Intercom Numbering: A station intercom
number can have as many as four digits, whereas
it is normally two digits. The numbers can be
assigned to any station port, and can be pro-
grammed in any sequence. Single-digit intercom
numbers, such as 0, can be assigned to an
attendant station.
Flexible Line Ringing Assignment: Each central
office (CO) line can be programmed to ring (or not
ring) any station in the system. A different ringing
assignment scheme may be created for each of
the three ringing modes—DAY, DAY2, or NIGHT.
Stations assigned to ring can do so with any of the
following three timing designations:
