Conferencing - Multiline
This feature allows one station to access other stations or lines at the same time resulting in a conference
arrangement. Users press the TRANS/CONF button to establish conferencing.
A station user can make conference calls that encompass up to five parties, including the originating
station, in any combination of lines and system stations. For example, a user can conference his or her
telephone with three lines and one other station.
After establishing a conference between his or her station and two external parties, the user can drop out
of the conference by dialing a special code. The conference between the two outside parties continues in
an unsupervised condition. During unsupervised conferences, a line-to-line connection exists through the
system.
The programmer can use the line-to-line connect duration feature to set the length of time that the system
allows an unsupervised conference to continue . Prior to software release 3A the maximum time that he or
she can choose is 30 minutes; however, beginning at software release 3A, the programmer can choose
never as a programming option. With this programming option active, an unsupervised conference will
never recall.
NOTE: Be careful when choosing this never recall option for systems that have loop start lines without disconnect
supervision. Both distant parties can leave an unsupervised conference thus leaving the line unused yet still
active. The line will remain active until the person that set the conference rejoins it to disconnect the line.
Conference Advisory Tone
Beginning with software release 4A, the conference advisory tone feature allows programmers to
configure the system to provide an audible tone whenever more than two parties are connected in a
conference call. They may select this tone as either a one time tone or as a periodic reoccurring tone. If
they choose a reoccurring tone, they must select the time interval between the reoccurring tones.
Console Support
The DXP Plus supports the operation of a DSS/BLF console. The system installer must use a station port
to install each DSS/BLF console; however, the programmer can assign up to four DSS/BLF consoles to
support the operation of one system station. When assigned to a station, a DSS/BLF console provides
additional programmable buttons that the user can program as direct station select (DSS) buttons with
associated busy lamp field (BLF) lights and as speed dial buttons (the console, however, does not support
second-level speed dialing). The programmer can also assign both outside lines and intercom numbers to
console buttons when necessary. The station with which the console is assigned to work does not have to
be a paired station port.
