Each dialing sequence component serves a different routing function:
• Dial Code Prefix:
Use service-specific dial code prefixes when sending a fax or using analog modems,
or for overriding system defaults to force the system to request a specific service
type.
Figure 2-1 uses the dial code prefix for 3.1 KHz audio service type (*82*). See
Table 2-2 for other dial code prefixes.
• International Access Code:
The international access code for all airborne equipment is 00.
• Country Code:
Use the Public Switch Telephone Network (PSTN) number assigned to the country
of your call destination.
• Area Code (and City Code, if applicable):
Use the PSTN routing number assigned to the area (and if applicable, city) of your
call destination.
• POUND SIGN (#):
To signal the system to send the call, at the end of the telephone dial string, press
or enter POUND SIGN (#). Certain devices using the HSD-440 Mark 2 Terminal may
not have the function to insert the POUND SIGN (#) 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 2-3 for more information.
(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 a fax, identify an analogue
modem, or force the system to override the system defaults to select a specific service
type (see
Table 2-2).
