||Interconnection of information technology equipment
This part of ISO/IEC 14165 describes a communication interface between a channel and I/O control units that utilize the Single-Byte Command Code Sets (SBCCS) as implemented in a wide range of data processing systems. It employs information formats and signalling protocols that provide a uniform means for communicating with various types of I/O control units, facilitating a high bandwidth, high performance and long distance information exchange environment. The signaling protocols and information exchanges are defined at a layer (FC-4) to compatibly utilize the link services and other functions provided by the ANSI Fibre Channel Physical and Signaling Interface (FC-PH) architecture (ANSI X3.230-1994, reference ). This FC-4 Upper Level Protocol is referred to as the Fibre Channel-Single-Byte-2 Command Code Sets Mapping Protocol (or for brevity, SB-2).
