Question 1 of 27070

To correctly address a SITOR (NBDP) message and transmit it "live" to a shore-based office the GMDSS operator would dial which sequence:

🔍 Key Concepts

• SITOR (NBDP) addressing format for Direct-Printing Telex (DIRTLX) calls • How country/area codes and subscriber numbers are structured in maritime telex addressing • Difference between ship-to-shore telex access code and normal telephone/telex numbers

💭 Think About

• Which part of the sequence represents the telex service designator, and which part represents the subscriber/office number? • Look at the digit groupings: which option has a realistic international telex access pattern for a shore office rather than a ship station? • If you remove the prefix (DIRTLX), which remaining number looks most like a valid shore-based office telex number you would actually be assigned?

✅ Before You Answer

• Check that the sequence starts with the correct service type prefix (for a direct telex call via NBDP) • Verify that the access code and the subscriber number are in a plausible length and order for an international shore telex • Confirm the ‘+’ end-of-address character placement is correct: it should come only after the full number, with no extra characters after it
