Components
System Operator Consoles. Telephones programmed to handle a
variety of operator functions. Types of consoles include:
— Analog or MLX Direct-Line Console (DLC). Outside lines are
assigned to individual buttons, and the console can have several calls
ringing at the same time. Only certain MLX telephones and analog
multiline telephones can be used as DLCs.
— MLX Queued Call Console (QCC). Available only in Hybrid/PBX
mode. Incoming calls wait in a queue for the operator and reach the
QCC on a first-in, first-out basis, according to the call priority level
assigned through system programming. Only one call rings at a time.
The MLX-20L telephone is the only telephone that can be assigned
through system programming to function as a QCC. The buttons on
the QCC are factory-set with fixed features.
The type of console used depends on the company's needs and the
system's mode of operation, as described earlier in this chapter.
NOTE:
One or two Direct Station Selector (DSS) adjuncts can be added to an
MLX console to provide 150 or 300 additional extension buttons. The
analog System Display Console has 40 built-in DSS buttons and provides
access to three pages of extensions, for a total of 120.
Auxiliary Components. Adapters for connecting extra equipment and
the adjuncts that add features to the system or extensions. Some
adjuncts are: loudspeaker paging systems, headsets, fax machines, and
modems. Other add-on components are optional accessories, for
example, surge protectors that protect the equipment from lightning and
power surges.
Figure 2–7 illustrates some of the components of the system. "Auxiliary
Components," later in this chapter and Chapter 3, "System Components,"
include additional information. The Equipment and Operations Reference
provides details about each component.
For more information or to order any of the components, contact your AT&T
representative.
