New originator STO starts back at what?

New originator STO starts back at what?

• A. 000
• B. 010
• C. 001
• D. 100

Answer: (B)

Starting a new originator STO requires a defined, non-zero starting state so the system can reliably recognize and synchronize with a fresh originator sequence. The designated initial code is 010 because it places the originator in a valid, non-idle state right away, which the framing and parity/checking logic expects. Using the all-zeros state would be interpreted as idle or no originator, risking misreadings at reset. Starting at 001 or 100 would set the sequence at a point that doesn’t align with the first expected transition, which could disrupt proper synchronization and validation. So 010 ensures a clear, detectable start and correct alignment with the rest of the sequence.
