Activating service  
Once registration is complete, your HSD Aeronautical 
Transceiver is assigned a Forward ID number—one for 
each channel card installed. These numbers act as ‘aircraft 
telephone numbers’.  
Each Forward ID is assigned INMARSAT Mobile Numbers 
(IMN). A different IMN is assigned to each type of 
communication service supported by Inmarsat Swift64 
(speech, 3.1k audio, 56k data, and 64k data, and 4.8 k). 
Two-channel systems are therefore assigned two IMNs for 
each service type.  
Each service type also has a Multiple Subscriber Number 
(MSN) associated with it. The MSNs are programmed into 
the terminal adapter or other routing device. They serve to 
identify the service type requested on outgoing calls and to 
recognize and route incoming calls to the appropriate 
system device (telephone, fax, or computer).  
Dial code prefixes are also associated with each type of 
service. Although the HSD Transceiver automatically 
selects the appropriate service, these dial code prefixes are 
used to override defaulted service types on a call-by-call 
basis.  
Table 1 shows the factory default assignments associated 
with each service—as defined by the HSD Transceiver’s 
channel card.
