Description Of System Features
IMI 66-097
Call Pickup - System
A user at any station can dial a special code and
answer a ringing call at any station in the system. The
feature can be enabled or disabled by system or ad-
ministration programming.
Call Transfer - Screened
Screened call transfer allows outside calls to be trans-
ferred from one station to another, via the intercom
link, in one of two ways. If both stations have access
to the line, a common line pickup transfer can be ef-
fected. If the other station does not have access to
the incoming line, transfer can still take place using
the system transfer feature.
For a screened transfer, a
call is transferred to another station with a pre-transfer
announcement by the transferring party. Transferring
of calls is accomplished with the T/C (TRANS-
FER/CONFERENCE) button.
Call Transfer - Unscreened
An active call can be transferred to another station
without being announced. The transferred call will ring
the other station and await an answer. The call will
automatically ring back to the transferring station after
a programmable recall period. A transferred call will
only ring if the station is idle. If the other station is
busy on intercom or is already ringing with another
call, the transferred call will immediately recall the
transferring station. If the other station is idle or has
background music enabled, it will start ringing immedi-
ately. If it is in any other state, it will not ring until it
returns to an idle state.
Calling Station Identification
If the station number of a calling station has been
programmed into the DSS/BLF of a called station, the
calling station will be identified by the flashing BLF
light at the called station. The lights adjacent to
programmable buttons indicate status of DSS
telephones: dark = idle, steady-on = in use, and
flash = calling.
Class Of Service .Programming (Each Line
And Station)
Each line and station in the system can be
programmed with a unique class of service operating
condition. Class of service programming can be per-
formed using instructions provided in Chapter 4.
Class Of Service Programming (From
Main Station)
Both system and administration class of service (COS)
programming is performed from station 10 after a base
level programming step is entered. System CCS
programming is used by the installer to configure the
system and assign the line conditions. Administration
COS programming is used by the on-site administrator
to re-configure the system as required. Line condition
assignment is not a part of administration program-
ming. Refer to Chapter 4 for programming details.
Common Audible Ringer Interface
Connections are available at the key service unit
which provide “dry-contact” relay closures whenever
an incoming line rings. These contact closures track
the ringing pattern and can be used to control an exter-
nal signalling device. When a particular station port is
programmed to be a PA port, the common audible
ringer interface contact points automatically become
supervisory contacts which close when the PA port is
called. In this configuration, they are used to enable
an external PA system. Also, see the discussion titled
Auxiliary Station Ringer Interface.
Default Functional Program
At initial power up of the system, the operating fea-
tures are set to a specific group of operating condi-
tions (default conditions). The default conditions
provide a complete operating system for normal use.
The system can be left as a defaulted system or
operating conditions can be reprogrammed if desired.
A system can be defaufted at any time using the
master clear procedure included with the system class
of service programming: however, this action also
clears all user stored auto dial and speed dial num-
bers.
Delayed Ringing
Refer to the paragraph titled Flexible Ringing Assign-
ments.
Dial 0 For System Attendant
The system attendant station (station 10) is signalled
whenever the digit 0 is dialed on the intercom line.
Direct Station Selection
Intercom
Refer to the discussion titled, Programmable DSS/BLF.
Distinctive Ringing
The ringing cadence of an incoming call is the same
as the ringing cadence of the TELCO, PBX, or
CENTREX system. The rfnging cadence of an inter-
com call presents two tone bursts sounded every 4
seconds.
