Information technology. Telecommunications and information exchange between systems. Protocol mappings for the OSI data link service Ingestion-build-48068 Pressure chambers for therapeutic use1 Scope This International Standard specifies general principles for the mappings between the OSI Data Link service (ISO IEC 8886), both connection mode (CO DLS) and connectionless mode (CL DLS), and standard Data Link protocols, as follows: M1: CO DLS HDLC X. 25 LAPB compatible DTE procedures, single link procedures (ISO IEC 7776) M2: CO DLS HDLC Unbalanced operation Normal response mode Class, UNC (ISO IEC 3309, ISO IEC 4335 and ISO IEC 7809) M3: CO
