Communications Card Support

The communications card provides serial data ports for interfacing such items as open architecture

interface applications, PC attendant positions, and the SMDA data printer. Technicians install

communications cards on the auxiliary board. The auxiliary board will accept two communications

cards in its front two slots. The FX II supports a maximum of 10 serial data ports. Two of these ports

are the ports provided by the CPU board while communications cards provide the remaining eight

ports. For related information, refer to the feature description titled Serial Data Port.

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 transfer/conference 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 installer can use the line-to-line connect duration feature to set the length of time that the system

allows an unsupervised conference to continue. The installer 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

The conference advisory tone feature allows installers 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 FX II supports the operation of a DSS/BLF console. The system installer must use a station port

to install each DSS/BLF console; however, the installer 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 installer 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.
