🔍 Key Concepts

• ARQ (Automatic Repeat reQuest) operation in NBDP/telex – how errors and repeats are handled • What operator commands like BRK+ and NNNN normally do in a telex/ARQ circuit • Effect of interrupting automatic answerback exchange versus normal end‑of‑message procedures

💭 Think About

• For each option, ask: does this event normally tell the system or operator to terminate the ARQ link, or is it something the system is designed to handle without breaking the connection? • Consider what role error percentage of repeats plays: when it gets too high, what protective action would the coast station likely take? • Think about which option describes a routine end of message procedure versus an abnormal or emergency break of a connection.

✅ Before You Answer

• Identify which choices clearly describe explicit break/termination commands sent by the operator. • Decide whether interrupting automatic answerbacks with keyboard use would necessarily force a break in the ARQ connection, or just pause/affect that part of the exchange. • Determine which option is most like a normal end-of-traffic signal rather than a signal to break the phased ARQ connection itself.
