CAN/CSA-Z243.54-1988 由 ISO 7809:1984/Amd 7:1991 信息处理系统.数据通信.高级数据链控制过程.过程等级的统一(本题录取代ISO6159 和ISO6256) 修改件7 变更而来。

This National Standard of Canada is equivalent to International Standard ISo 7809-1984. 1 Scope and field of application This International Standard describes the HDLC unbalanced classes of procedures and the HDLC balanced class of procedures for synchronous data transmission. Balanced operation is intended for use in circumstances which require equal control at either end of the data link. Operational requirements are covered in accordance with the overall HDLC architecture. The procedures use the HDLc frame structure defined in ISO 3309 1) and the HDLC elements of procedures described in ISO 4335 2). For the unbalanced classes, the data link consists of a primary station plus one or more secondary stations and operates in either the normal response mode of the asynchronous response mode in a point-to-point or multipoint configuration. For the balanced class, the data link consists of two combined stations and operates in the asynchronous balanced mode in a point-to-point configuration. In each class, a basic repertoire of commands and responses is defined, but the capability of the data link may be modified by the use of optional functions. 1) ISO 3309, Data communication - High-level data link control procedures - Frame structure. 2) ISO 4335, Data communication - High-level data link control procedures - Consolidation of elements of procedures.
