What error message may be displayed if a connection to the Inmarsat Mobile Packet Data Service (MPDS) network fails?

🔍 Key Concepts

• Inmarsat MPDS (Mobile Packet Data Service) registration requirements before data can flow • Meaning of hexadecimal-style error codes like 00F0h / 00F1h / 77F0h / 77F1h • Difference between an error for not being registered and errors for call setup / transmission failures

💭 Think About

• Ask yourself: which error would most logically appear before any data transmission is possible, when the terminal has not successfully joined the network? • Look at the patterns in the codes: which pair of codes is grouped together in practice for very similar conditions (e.g., one for attach, one for PDP context)? • Consider which answer choices talk about ID decoding or failure to transmit—would those conditions happen after registration, or instead of it?

✅ Before You Answer

• Verify which codes are typically documented as registration/attach-related vs traffic/transmit-related in Inmarsat MPDS material. • Check that the correct choice mentions "not registered to the MPDS network" and pairs it with the proper hexadecimal code pattern. • Make sure you are not selecting an option that describes a problem with called station ID or failure to transmit, since those usually assume the terminal is already registered.

What error message may be displayed if a connection to the Inmarsat Mobile Packet Data Service (MPDS) network fails?

"ECM 0071" is displayed indicating the called station ID was not properly decoded.

"ECM 00F0" is displayed indicating the terminal's failure to transmit over the Inmarsat network.

"77F0h" or "77F1h" is displayed indicating the terminal is not registered to the MPDS network.

" 00F0h " or " 00F1h " is displayed indicating the terminal is not registered to the MPDS network.
