适用范围：This International Standard describes the HDLC unbalanced classes of procedures for synchronous data transmission. It covers operation requirements in accordance with the overall HDLC architecture. It uses the frame structure as defined in ISO 3309 and elements of procedure described in ISO 4335 and its addendum ISO 4335/DAD 1.The link consists of a primary station plus secondary stations, and operates in either the asynchronous or normal response mode. A basic repertoire of commands and responses is defined. The capability of the data link may be modified by the use of optional functions.
