General Purpose Adapter 3

A General Purpose Adapter (GPA) enables you to connect a tip/ring (T/R) device—such as a single-line telephone, modem, or answering machine—to an analog multiline telephone. The device must be touch-tone, not rotary, and you must make calls from the analog multiline telephone, because the GPA has no pulse or touch-tone detectors.

The switch on the back of the GPA lets you choose one of the following services:

■Basic. Use this setting to dial and answer calls on an analog multiline telephone or to attach a T/R device such as a single-line telephone or a fax machine. Incoming calls ring only on the analog multiline telephone.

■Join. Use this setting to add a recording device or a single-line telephone to a call that is in progress on the analog multiline telephone. You cannot originate or answer calls on this setting.

■Automatic. When using a GPA set to Automatic, you must lift the handset before using any feature that automatically turns on the speakerphone. These features include Authorization Codes, Auto Dial, Last Number Dial, and Saved Number Dial. You can use this setting in two ways:

—For devices that answer calls, for example, an answering machine or a modem (you need a programmed Auto Answer All button to allow the device to answer calls automatically).

—For voice and data, which enables you to make and receive calls on the telephone when the modem attached to the GPA is busy. You cannot make or receive a data call while on a voice call.

A GPA is not recommended for use with a fax machine. See ‘‘Fax Machines’’ on page 3-37.
