Understanding the GFUT Installation
Qualcomm Proprietary 80-25808-1 X1 5
Installing your GFUT
Your service provider will perform the GFUT installation.
Qualcomm may supply a telephone with your GFUT
installation for you. (See Figure 2.)
If you purchased a basic Globalstar telephone kit, you will
need to purchase an off-the-shelf two-wire telephone set. You
can either purchase a qualified and tested telephone from
Qualcomm or you can buy one that meets Qualcomm
requirements.
Selecting a telephone
If you are selecting your own telephone, look for one that best
fits these guidelines. For optimal results, a telephone should:
■ Use standard DTMF tones, not pulses, for dialing. This is a
requirement.
■ Have good voice quality. Sound quality is determined by
the telephone itself as well as by signal reception. Your
Globalstar phone installer can ensure proper placement of
components to obtain the best signal reception.
You can connect one or more telephones to your GFUT. When
using several telephones, an individual telephone should be
.5 to 1.5 REN (ringer equivalent number). The total load of all
the phones when added together can not exceed 5.0B REN.
(You can discuss this requirement with your service provider.)
Activating the GFUT
When the building was wired for GFUT, jacks for the telephone
were installed, or existing jacks may have been connected to
the Globalstar GFUT components. If your installer did not plug
the telephones into the jack, do so now.
