Note: The GPA is intended for answer-only service. Calls must
be originated (dialed) by using the associated analog multiline
telephone. The GPA has no touch-tone receivers or pulse dial
detectors for dialing.
Plug one end of a 4-pair cord into the V.T. jack on the back of the
GPA and the other end into the OTHER jack on the underside of
the telephone. Plug the cord from the adjunct into the TEL.
EQUIP. jack on the GPA (see Figure 67).
Slide the switch on the back of the GPA to the setting that
provides the GPA service required.
Basic. This setting is used to dial and answer calls from an
analog multiline telephone or to attach a T/R adjunct such as
a single-line telephone, answering machine, or fax machine.
Incoming calls ring only on the analog multiline telephone.
Join. This setting is used to add a recording device or a
single-line telephone to a call that is in progress on the
telephone. You cannot originate or answer calls on this
setting.
Automatic. This setting is used in two ways:
with a device, such as an answering machine or a
modem, to answer calls. An Auto Answer–All button is
needed so that calls can be answered automatically.
to make and receive calls on the telephone while using a
computer or modem that is attached to the GPA. This is
called "simultaneous voice and data."
