The system requires the dial code prefix *82* for sending faxes or when using
analogue modems. It forces the system to request the required 3.1 kHz audio service
from the Inmarsat Satellite Communications Network. If required, use the dial code
prefixes to override the system defaults for selecting specific service types. Dial code
prefixes for all service types require an asterisk (*) before and after the code number.
Other dial code prefixes provide system overrides required if you are using devices
that cannot add a POUND SIGN (#) to the dialing string or devices that are slow
dialing.
Table 2-2 provides a description of the additional dial code prefixes used for
system overrides. Table 2-1 provides a list of the LESs and their associated codes.
