The TEL & FAX port can be dedicated to voice operation. In
this case the destination phone number need only be dialled.

Similarly, the TEL & FAX port can be dedicated to fax
operation and no prefix digit is required.
For configurations where a 2 Wire phone and fax machine are
connected to the TEL & FAX port, a prefix digit must be
entered before the phone number to set the call type.

Note: The Optus MobileSat S2 can only drive a 2 Wire load of 3 ren. Ensure
that combinations of 2 Wire equipment do not exceed 3 ren.
For example: If a fax and 2 Wire phone are connected to the
TEL & FAX port and the destination phone number is 03 9264
3050 the following buttons should be pressed when a fax is to
be sent:
2 0 3 9 2 6 4

The prefix digit sets the call type in the Optus MobileSat
S2 and is not sent to the earth station.

Note: If a fax and 2W phone are connected to the TEL & FAX port there is a
risk that the fax will automatically answer an incoming voice call before the
handset is picked up. Ask your dealer to provide a Fax Switching cable so
that the fax does not 'steal' voice calls.

Prior to Commencement:
• Prior to purchasing a fax machine ask your Authorised
MobileSat Dealer for a list of compatible fax machines.
• When purchasing a fax machine, if possible, perform some
test faxes to commonly required terrestrial numbers. Use
different fax machines and choose the one that gives you
the best results.
• Ensure you properly understand the functionality of the TEL
& FAX port and FCN 31 and the effect it will have on
sending and receiving faxes. (Refer to Page 104).
• Ensure you fully understand how to send and receive faxes.
(Refer to Page 16 and Page 25).
• Ensure that FCN 35 is set to 2Wire On, without this faxes to
and from the Optus MobileSat S2 will not work. This
function is by default set to 2Wire On.
Hints for Sending:
• Optimise antenna tuning for best received signal strength.
• Ensure the fax machine is receiving dial tone from the
Optus MobileSat S2, without dial tone your faxes will not be
sent or received. This can be done by placing a standard
telephone handset on your 2W Fax cable to verify that dial
tone is indeed being emitted from the TEL & FAX port of the
Optus MobileSat S2.
• Ensure that the number you wish to dial is actually dialled
by checking the fax machine's LCD display.
• If your fax machine will not transmit faxes, firstly re-check
all your fax machine configurations and options menus to
ensure all is correct (Note: Standard configuration
options/settings are optimal). Next try using your fax
machine over a terrestrial link to ensure its functionality.
There is a chance that the fax which you are using is not
compatible with the S2.
• For greater fax transmission success it is recommended
that standard or draft transmission modes be used. Do not
use Fine setting.
• Ensure fax is set for ECM = off (Error Correction Mode)
• In mobile vehicle fax transmissions, ensure power supply to
the Optus MobileSat S2 and fax machine is adequate.
