This paper presents the results of a contract between ARL and the University of Delaware to develop a formal specification of the link layer of 188-220 using the ISO International Standard Formal Description Technique Estelle. This formal specification aims at discovering and resolving ambiguities in the original English document that would cause interpretation problems for implementors. The specification considers Type 1 connectionless (CL) operation of the link layer. It contains the complete
