Link layer

(Network-specific parameter, mark all used options with an "X". Specify the
maximum frame length. If a non-standard assignment of class 2 messages is
implemented for unbalanced transmission, indicate the Type ID and COT of all
messages assigned to class 2.)
Frame format FT 1.2, single character 1 and the fixed time-out interval are used
exclusively in this companion standard.
