🔍 Key Concepts

• Coast station radiotelex (NBDP) call sequence and what happens automatically when you first set up a call • The purpose of the DIRTLX (direct telex) command in an HF/MF radiotelex exchange • What the Go Ahead indication means in the standard telex/radiotelex procedure

💭 Think About

• First, list the normal order of events in a radiotelex call to a coast station: call, answerback, Go Ahead, message, etc. Where in that sequence would it make sense to request a direct telex connection? • Think about what is already exchanged automatically when you call the coast station. Would you need to send DIRTLX before or after that automatic exchange? • Ask yourself: does the coast station tell you it is ready to receive further commands (like DIRTLX) before or after the Go Ahead signal?

✅ Before You Answer

• Be clear on the difference between the automatic exchange of answerbacks and the Go Ahead indication—which one comes first? • Verify what DIRTLX actually does: it requests a direct connection to the public telex network via the coast station, not just a simple radiotelex message to the coast station itself. • Check that the timing you pick allows the station to have fully recognized the ship’s call and given permission to proceed (i.e., you’re not sending DIRTLX too early, before the system is ready).
