Q

All country codes which are transmitted by MF/HF SITOR (NBDP) are preceded by which character(s)?

🔍 Key Concepts

• MF/HF SITOR (NBDP) address and country identification formats • How country codes are formatted in maritime telex-style or NBDP calls • Difference between simple numeric prefixes and special characters in signaling formats

💭 Think About

• Think about whether country codes in international telecommunications are usually pure numbers or if they are often marked off by a special non‑numeric character first • Compare which options look like something that would appear in front of a three‑digit country code in a telex/NBDP address field • Consider whether an operator needs a clear visual separator between the country code and the rest of the address, and which option best serves that function

✅ Before You Answer

• Verify in your study material how a country code appears in a sample MF/HF SITOR (NBDP) call setup or address field • Check whether the prefix is a single character or a pair of characters • Confirm whether the prefix is numeric or a symbol, and eliminate the answers that don’t match what you’ve seen in actual NBDP examples
