Is applicable to data station procedures which provide the XID command/response capability with the two specific parameter fields, identified below. It is used to select a pair of operational link addresses when preassigned, systems designated addresses are not known on an a priori basis, e.g. switched circuit data links. Additional XID frame functions (including the exchange of operational parameters, command/response support, higher layer information, etc.) may be accomplished in conjunction with data link layer address determination or following address determination, with additional XID frame exchanges. Technically identical with ISO 8471:1987.

This International Standard is applicable to data stations employing HDLC balanced classes of procedures which provide the XID command/response capability with the two specific parameter fields, identified below. It is used to select a pair of operational link addresses when preassigned, system designated addresses are not known on an apriori basis; e.g., switched circuit data links. Additional XID frame functions (including the exchange of operational parameters, command/response support, higher layer information, etc.) may be accomplished in conjunction with data link layer address determination or following address determination, with additional XID frame exchanges.NOTE - Address resolution procedures for situations where the remote DTE does not have XID frame, "all-station" address, or complete address support capabilities as deemed in clause 4 below are not within the scope of this International Standard.
