and later systems, you can use this access arrangement, as well as digital
facilities supported by the system, to use network services from various
telecommunications companies. For more information, see the
Feature Reference
and ‘‘

This section provides an
overview
of the applications and services that you can

■
System Planning

■ The documentation for specific products and services provides the most
detail. None of the system guides present full information about the
operation and installation of specific applications. (Applications are,
however, installed by Lucent Technologies.) Consult your Lucent
Technologies representative after you review the system guides.
NOTE:
There are important differences in how applications function in the
system’s different modes of operation (Key, Hybrid/PBX, or Behind
Switch). Also, there may be interactions between an application and certain
system features. For more information, see the
Feature Reference
or
contact your Lucent Technologies representative.
As you review information about the available applications, ask these questions:
■ What adjunct hardware and software are required for the application? Does
a UNIX System, DOS, or Windows
environment match my expertise or that
of others who may use the application?
■ How does the application work with the features and settings already
programmed for the system?
■ Are additional line/trunk and/or extension modules necessary to
accommodate the application?
This section summarizes applications in general, then presents some specifics
regarding voice messaging applications.
