Busy Station Transfer/Ringing: When a station or
external auto attendant device programmed for
this feature transfers a call to a busy digital or
electronic telephone with this feature, the transfer-
ring station or auto attendant device will receive a
ringing signal (instead of a busy tone) and the
called busy station will receive a distinct call wait-
ing tone and LED indication. At this point, the
transferring station or auto attendant device will
normally release and the call will camp-on the
busy station, providing a distinctive camp-on tone
and CO line LED flash. The busy station can then
answer the transferred call after it releases, trans-
fers, or places its current call on hold. Without
Busy Station Transfer/Ringing, stations and auto
attendant devices will receive busy tone when try-
ing to transfer calls to busy stations. Some auto
attendant devices cannot transfer calls after
receiving busy tone, and the transferred calls are
routed back to them.
Centrex/PBX Compatible: All system features are
compatible with Centrex/PBX operation; including
repeat of Centrex/PBX ringing cadence, one-but-
ton access to Centrex/PBX features, 1 ~ 4-digit
station numbering plan, and delayed ringing to
selected stations.
Centrex Ringing Repeat: The system mimics
CO/Centrex/PBX cadences received from outside
lines when it rings a called station. This capability
enables STRATA DK8 and DK16 to use special
CO/Centrex/PBX calling/callback features.
CO Line Groups: For easy access, various types of
CO lines can be assigned to groups (normally for
pooled line and Least Cost Routing (LCR) applica-
tions). All local lines, for example, can be assigned
to one group and WATS lines in another group.
Station users can access line groups with a dialing
code or by pressing a feature button. Up to four
CO line groups for DK8 and up to eight CO line
groups for DK16 can be created.
CO Line Queuing: A station user can use the Auto-
matic Callback feature to queue up for a busy out-
going CO line. When the CO line finally becomes
available, the system calls the station back. Queu-
ing applies to single CO lines, CO line groups, and
when calling via LCR.
Conferencing: A variety of Conferencing combina-
tions are available to all station users, as listed
below. Stations and central office (CO) lines can be
added in any order.
•
One or two stations and two CO lines
•
Two or three stations and one CO line
•
Four stations
Credit Card Calling: Callers can make credit card
calls (0+ telephone number + credit card number)
that bypass Toll Restriction. The calls are billed to
the credit card, not the STRATA DK8 and DK16
central office (CO) line. The system requires that a
specific quantity of digits are dialed for this call;
otherwise, the call will be dropped within 20 sec-
onds to prevent operator-placed calls that would be
billed to the CO line.
Data Calling: STRATA DK8 and DK16 offers a
sophisticated optional data switching capability that
can interconnect a wide range of customer-sup-
plied data equipment, including personal comput-
ers (PCs), printers, and modems. Asynchronous
data can be transmitted at speeds up to 19.2 kbps
(see Table M). The system provides four data
security groups to restrict data calls between
groups. Dialing by personal computer (both data
and voice calls) as well as modem pooling and
printer sharing is supported.
DAY/NIGHT Modes: The system has three available
modes: DAY, DAY2, and NIGHT. Each mode can
be assigned a distinct CO-to-station, CO-to DISA,
and CO-to-Remote Maintenance channel ringing
arrangement. The system can be programmed with
either two or three modes (which can be changed
by any station programmed with a Night Transfer
button):
Two modes: Three modes:
DAY
NIGHT
Delayed Ringing: If a central office (CO) line call
rings a station and is unanswered, alternate sta-
tions can be programmed to ring 12 or 24 seconds
later. The stations that were ringing initially will
continue after the Delayed Ringing begins. This
feature is assigned on a line-by-line basis.
Direct Inward System Access (DISA): Outside
callers using a Dual-tone Multi-frequency (DTMF)
