(Network-specific parameter, all options that are used are marked 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 (Cause of Transmission) 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.
