🔍 Key Concepts

• ARQ (Automatic Repeat reQuest) telex procedures between ship and coast station • Meaning of control codes like WRU-AAB, DIRTLX, GA+?, NNNN/KKKK/BRK+ in maritime telex traffic • Proper call, traffic, and clearing sequence in a ship–shore radio-telex exchange

💭 Think About

• First, identify which code group represents the coast station saying it is waiting for the vessel to say what it wants to do. Which of the listed items is a standard “who are you / what do you want?” or “go ahead” toward the vessel? • Next, decide which of the middle items correctly represents the vessel asking for a direct connection to a land telex subscriber (landline telex number). Focus on which code literally means direct telex. • Finally, determine which of the ending groups is the standard way for a vessel to indicate that it has finished with the coast station and is clearing the radio-telex circuit. Compare NNNN, KKKK, BRK +, and ..... with what you have learned about clearing down telex calls.

✅ Before You Answer

• Verify in your study materials which code means direct telex via coast station (ship asking for connection to a land telex number). • Confirm which ending sequence is the standard clearing signal when a radiotelex call is finished (look carefully at NNNN vs KKKK vs BRK+ vs .....). • Check which of WRU-AAB or GA+? is actually sent by the coast/shore station to show it is waiting for the ships instructions, not the other way around.
