STRATA DK
GENERAL DESCRIPTION
DECEMBER 1990
Tandem CO Line Connections: This feature
altews an unattended line-to-line connection,
leaving the originating station free to make
another call. For supervision purposes, the
originating station must have both CO line but-
ton appearances to allow tandem operation.
Therefore, tandem calls cannot be set-up from
standard telephones, digital telephones, or
electronic telephones using LCR, pooled line
buttons, or CO line access codes.
Tenant Service: Two small businesses in the
same office building which do not each require
a full system can share a system. Each ten-
ant’s CO line buttons appear in the correct
sequence on stations. Each tenant can have
two dedicated DSS consoles. Tenants can
also call each other directly. Tenants can have
separate:
l
LCR and toll restriction plans.
l
Night transfer ringing assignments.
l
Flexible door phone and CO line ringing
assignments.
TIE Lines: TIE lines can be installed to link
STRATA DK systems to one another, or to link
a STRATA DK system to a PBX or any other
system with TIE lines. System configuration
allows a maximum of four TIE lines on DK24,
eight on DK56, and twelve on DK96. TIE lines
are interfaced via the PEMU PCB, each of
which provides four circuits. TIE lines are E &
M Type I signaling, optional 2- or 4-wire trans-
mission, immediate start.
l
Paging system (external and station
speakers) access by far-end callers origi-
nating TIE line calls can be denied or
allowed in system programming.
l
System programming allows or denies
handsfree answerback on incoming TIE
line calls.
l
Off-hook call announce is not available
over TIE lines.
Toll Restriction*: Stations can be individually
restricted from making toll calls. Four restric-
tion levels can be defined, each allowing or
denying specific area and office codes, long
distance information calls, international calls,

and/or operator-assisted calls. Each station is
assigned any one of t.he available restriction
levels or no restrictionT Individual CO lines can

be defined as unrestricted. By dialing one of
the two toll restriction override codes pro-
grammed into the system, a user can bypass
toll restriction. Also, a user can temporarily
change a station’s toll restriction class (See
Station Features: Traveling Class of Service,
Toll Restriction Override Code Revision, and
Verified Account Codes).T
Toll Restriction Override by System Speed
Dial*: System speed dial numbers can be
programmed to override toll restrictions. For
instance, when employees need to access a
toll number that falls into a restricted area/
office code for work purposes, an employer
can program the particular toll number as a
system speed dial number. Even if their sta-
tions are toll restricted, they can access the
number with speed dialing.
Transfer Privacy: Optional transfer privacy can
be programmed system-wide. When transfer
privacy is programmed and an outside call is
4
answered by one station, then transferred to
another station, it can only be answered by the
second station, or by a station with directed
call pickup. Other stations cannot pick up the
transferred call with a CO line button. See
Alternate Point Answer and Directed Call
Pickup.
Traveling Class of Service-t: The normal toll
restriction class of a station can be temporarily
changed to another class. Each of the four toll
restriction classes can be assigned a four-digit
code. If one of these codes is entered at any
station, the station will assume the class asso-
ciated with the code for the next dialed num-
ber. The station will revert back to its normal
toll restriction class for subsequent calls. In
system programming, any station can be
assigned to change these codes. The traveling
class code data is not sent out the SMDR port
and will not print out on station call records.
Traveling class codes can be added, deleted,
or changed by users from stations selected in
programming.
