Introduction
The ARNAV Systems, Inc. RCOM-100 is a
Globalstar satellite telephone system. The RCOM-
100 interfaces with telephone handsets or aviation
equipment with a standard “POTS” (Plain Old
Telephone Service) interface. This interface is
sometimes called a “Tip/Ring” interface. Any
compatible telephone handset can interface with the
RCOM-100, but in an airplane it must be used with
aviation-approved equipment.
The equipment in the Cessna, Model 180 aircraft
includes an NAT PTA-12 POTS Telephone Adapter
that is interfaced with a UPSAT SL15 Audio Panel.
The controls on the audio panel can be used to
answer an incoming phone call, but the PTA-12
must be used in conjunctions with the audio panel
to make a phone call.
The RCOM-100 handles the communication with
the ground based telecommunications network in a
fully automatic method. The RCOM-100 simply
acts like a normal telephone from the users
perspective.

Systems Description
Audio Panel
The audio panel is used to interface cockpit or cabin
headsets and microphones to the telephone
system. The SL15 audio panel has a “TEL” position
on its selection switch that connects the audio
channels to the “Tip/Ring” telephone interface that
is tied to the RCOM-100. The audio panel controls
can be used by themselves to answer an incoming
call, but must be used in conjunction with the PTA-
12 Dialer device to make a phone call or to keep a
phone call active while changing audio panel
selections.
PTA-12 POTS Telephone Adaptor
(Dial Device)
The PTA-12 also connects to the “Tip/Ring”
interface of the RCOM-100. The PTA-12 could
optionally be wired directly to the
headset/microphone system, but its primary
function in the Cessna 180 equipped with the SL15
audio panel is to provide dialing capability to initiate
a phone call.
The PTA-12 Keypad includes the numbers 0 – 9
and the * and # keys for dialing telephone numbers.
There are also control buttons – Volume Up/Down,
Redial, Flash, Hold, and Hook.

In this application the Volume, Hold and Flash
buttons are not used.
“Hook” is used to start and stop a call that is being
initiated from the airplane. It is not used when
answering an incoming call unless the user wants
to keep the phone line connected while changing
audio panel selections.
The “Hook” button can be pressed after answering
a call on the audio panel in order to keep the line
connected to the calling party while audio panel
selections are changed (for example: if a call is in
progress, but the pilot needs to change the audio
panel switch to “COM” or “NAV” and does not want
to hang up on the caller).
“Redial” is used to dial the last dialed number again.
In installations where the PTA-12 audio system is
used with headsets and microphones or as an AUX
input to an audio panel without “Phone” capabilities,
the Volume and Hold functions would be available
for their normal functions.
Indicator
There is a “Hook Status / Ringer Active” annunciator
located above the “Hook” button. The LED is off
when the unit is inactive (“On-hook”) and is
illuminated continuously when the unit is active
(“Off-hook”). If the unit is inactive and waiting for a
call the LED will FLASH to indicate an incoming call.

Placing a Call
The RCOM-100 is part of the Globalstar network. In
order to make a call on the network you MUST dial
a 1 plus a full TEN-digit number. The number
includes the standard area code and the seven digit
local number. To dial international numbers dial
the country code and full number.
The RCOM-100 is taken off hook by selecting “TEL”
on the audio panel select switch. After selecting
“TEL” there will be a dial tone on the audio system.
Press the “Hook” button on the PTA-12 and then
dial 1 plus the 10-digit number.
After the call is complete, press, “Hook” on the PTA-
12 and move the audio panel select switch to any
position other than “TEL”. Both the audio panel
selector and the “Hook” switch on the dialer must
be off or the phone is still off hook (has not hung
up).
Receiving a Call
When a call comes into the RCOM-100 a ring is
heard on the pilot’s headset and the “Hook / Ring
Status” LED on the PTA-12 will flash.
The call is answered by selecting “TEL” on the
audio panel. The PTA-12 controls are not needed
to answer an incoming call, but the “Hook” switch
can be activated in order to keep the line connected
while making different selections on the audio panel.

other than “TEL” on the audio panel and pressing
“Hook” on the dialer if it has been pressed to hold
the line open.
