–All separate entities in a message are represented between curly brackets, e.g. {CRC}

–Literal strings are between quotes, e.g. 'P'

–Logical entities are neither between brackets nor quotes, e. g. Mic.-No.(microphone number)

–A logical entity will also contain a number between brackets. This number states how many characters the entity exists of, e.g.(4)

–Volume, treble, middle and bass response are two-digit values from “00” (minimum) to “12” (maximum)

–The two-digit numbers for the conference modes are: “00” (No Request), “01” (With Request), “02” (With Req. No Clear), “03” (Direct Access), “04” (FIFO),
