SYSTEM DESCRIPTION, INSTALLATION, AND MAINTENANCE MANUAL
eNfusion™ HSD-128 High-speed Data Terminal
# (SEND):
Pressing # (or entering # at the phone number field on data devices) signals the
system to “send” the call. Certain devices using the HSD system may not have the
functionality to insert the # symbol at the end of the dialing sequence. For those
devices, additional Dial Code Prefixes are required to override the “send” command
requirement. Refer to
Table 2–10 for more information.
Note: For more information on using the HSD transceiver for voice and fax, refer to the
HSD User Guide (MN-1110-10048).
(1) Dial Code Prefixes
Although the system automatically selects the appropriate service types on outgoing
calls for ISDN devices, a Dial Code Prefix is required to send fax, identify an analogue
modem, or force the system to override the system defaults to select a specific service
type. (See
Table 2–9.)
The system requires the Dial Code Prefix *82* for sending fax 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 a “
¿” before and after the code number.
Other Dial Code Prefixes provide system overrides required if you are using either
devices that cannot add a # symbol to the dialing string or devices that are slow dialing.
Table 2–10 provides a description of the additional Dial Code Prefixes used for system
overrides. Table 2–6 provides a list of the LES and their associated codes available.
