In addition, Centrex services are supported by the system; Centrex is supplied by a service provider. The system also allows the use of the Primary Rate Interface (PRI) platform for accessing servicesto which you can subscribe. In Release 4.2 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 ‘Modules‘ Supporting Lines/Trunks’’ on page 3-7.

This section provides an overview of the applications and services that you can connect to the system. If you are considering adding any of these products to your system, see the following system reference guides for more information:

■Feature Reference for information about some considerations you need to take into account

■System Planning for planning instructions

■System Programming for detailed system programming instructions

■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.
