2-Wire Configuration
The Optus MobileSat S2 allows 2 wire phones to connect straight
into the front panel TEL & FAX port.
Figure 6 – Remote Telephone Installation
As this port can be used either for 2W telephone, or fax, it is
necessary to inform the Optus MobileSat S2 which type of call
(voice/fax) is being requested. A prefix digit can be used to do
this. Alternatively, by changing FCN 31 setting, you can configure
your installation so as not to require these prefix digits. (See
Placing a Call and "FCN 31: 2W TEL/FAX" on page 104 for
further details.)
However, if both an external 2W phone and fax machine are used
together in your installation, prefix digits will need to be used for
