■The features and applications that your business can use and how they work

■How the system is registered with the Federal Communications Commission (FCC)

The choice of system mode depends on your company’s needs. Your Lucent Technologies representative and you or your company’s representative decide on the system mode when you plan and purchase your system. Lucent Technologies personnel then set the mode when they install the system.

!CAUTION:

Because the operating mode significantly affects how the system works, you should know the mode in which your system is configured. You can either check the Planning Forms (Form 1, Page 2, System Mode) or contact your Lucent Technologies representative.

The system operates in one of three modes:

■Key Mode. The simplest way to provide people with more than one line from a telephone. Easy to use. Recommended for smaller systems.

■Hybrid/PBX Mode. Especially useful where toll fraud/security are a concern. Provides cost-effective call routing, especially useful for special-purpose network services. Recommended for medium to larger systems.

■Behind Switch Mode. Used when the system is connected to a system such as DEFINITY. May be appropriate for users who are part of a large organization, for example, a department within a company.

While Key mode is appropriate for smaller systems and has the capacity limitations of any key system, the MERLIN LEGEND Communications System, unlike other key systems, is flexible and allows you to expand to a PBX system when your business outgrows Key mode.

Table 2–1 outlines the primary differences among the modes.
