This International Standard defines a single-exchange negotiation procedure for establishing operational characteristics when either one or more stations are capable of providing multiple selections.
Mitigate liability and better understand compliance regulations Boost efficiency: Click here to skip or iso iec 13239 will close in 15 seconds. It defines encoding for information related to the basic HDLC standards only. IHS Standards Expert subscription, simplifies and expedites the process for finding and managing standards iso iec 13239 giving you access to standards from over standards developing organizations SDOs. It describes a general purpose XID frame information field content and format for that purpose.
Identify unmet needs and discover next-generation technologies Improve quality by leveraging consistent standards to meet customer and market requirements Minimize risk: Operational requirements are covered in accordance with the overall HDLC architecture. This International Standard provides a means for exchanging the necessary information to establish, at a minimum, a data link connection between two correspondents wishing to communicate.
In addition, three frame checking sequences FCS are specified; iso iec 13239 rules for address field iso iec 13239 are defined; and the addressing conventions available are described.
These HDLC elements of procedures are defined specifically in terms of the actions that occur on receipt of commands at a secondary station, a tributary station, a peer station, or a combined station. This standard is available for individual purchase. It is used to select a pair of operational iso iec 13239 addresses when preassigned, system designated addresses are not known on an a priori basis; e.
For the unbalanced connectionless class, the data link consists of a control station plus one or more tributary stations and iso iec 13239 in the unbalanced connectionless-mode in a point-to-point or multipoint configuration.
The defined elements of procedures are iso iec 13239 be considered as a common basis for establishing different types of data link control procedures. Speed up research, capture and reuse ido For additional product information, visit the IHS Standards Expert page.
Standard: ISO/IEC 13239
This International Standard does not limit 31239 restrict the use of the XID frame information field from defining other standard formats for use in specific applications. The mechanisms used to achieve jec pattern independence transparencywhere and when required, within the frame are also defined. The frame structure portion defines the relative positions of the various components of the basic frame format and the nonbasic frame format. For the unbalanced classes, the data link iso iec 13239 of a primary station plus one or more secondary stations and operates in either the normal response mode or the asynchronous response mode in a point-to-point or iso iec 13239 configuration.
This International Standard does not define any single system and should not be regarded as a specification for a data communication system. Balanced operation is intended for use in isl which require equal control at either end of the iso iec 13239 link.

NOTE — Address resolution procedures for situations where the remote DTE does not support Iso iec 13239 frames, the “all-station” address, or complete address support capabilities as defined in clause 8 below are not within the scope of this International Standard.

Mechanisms are provided to permit the general purpose XID frame information field to be used to negotiate private parameters in a single XID exchange simultaneously with negotiation of the defined basic parameters.
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.
