Editing Transmission block

In [[telecommunications]], the term '''transmission block''' has the following meanings:

#A group of [[character (computing)|characters]] or [[bit]]s transmitted as a [[block (telecommunications)|block]], unit, [[message]], or [[network packet|packet]]. It usually includes additional encoded characters for [[error detection and correction]].
#In [[data transmission]], a group of records sent, processed, or recorded as a unit.

Some protocols require each transmission block to end with an [[end of message|end-of-message]] marker. This is often a [[control character]] such as [[End-of-Text character|End-of-Text]] (ETX), [[End-of-Transmission-Block character|End-of-Transmission-Block]] (ETB), or [[End-of-Transmission character|End-of-Transmission]] (EOT).

Some protocols (especially those requiring ETX) require each transmission block to begin with a [[Start-of-Text]] character (STX).
