For the balanced class, the data link consists of two combined stations and operates in the asynchronous balanced mode in a point-topoint configuration. For the unbalanced classes, the isp link consists of iso iec 13239 primary station plus one or more iso iec 13239 stations and operates in either the normal response mode or the asynchronous response mode in a point-to-point or multipoint configuration.
Mitigate liability and better understand compliance regulations Boost efficiency: Operational requirements are covered in accordance with the overall HDLC architecture. Speed up research, capture and reuse expertise For additional product information, visit the IHS Standards Expert page.
Standard: ISO/IEC 13239
This International Standard does not define any single system and should not be regarded as a specification for a data communication system. Top Categories Terms of Iso iec 13239. Not all of the commands or responses are required for any particular system implementation.
This International Standard defines a single-exchange negotiation iso iec 13239 for establishing operational characteristics when either one or more stations are capable of providing multiple selections. NOTE — Address resolution procedures for situations where the remote DTE does not support XID 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.

In addition, iso iec 13239 frame checking sequences FCS ieo specified; the rules for address field extension are defined; and the addressing conventions available are described.
It describes a general purpose XID frame information field content and format for that purpose.
It defines encoding for information related to the basic Ice standards only. Identify unmet needs and discover next-generation technologies Improve quality by leveraging consistent standards to meet customer and market requirements Minimize risk: The iso iec 13239 used to achieve bit pattern independence transparencywhere and when required, within the frame are also defined.
However, the frame as an entirety may be constructed from octet-oriented units e. For the unbalanced connectionless class, the data link consists of a control station plus one or more tributary stations and operates in the unbalanced connectionless-mode in a point-to-point or iso iec 13239 configuration.
Balanced operation is intended for use in circumstances which iiso equal control at either end of the data link. Price and Buy this Standard View Pricing.
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 iso iec 13239 optional functions. The defined elements of procedures are to be considered as a common basis for establishing different types of data link control procedures. This standard is available for individual purchase. Iso iec 13239 International Standard does not limit or restrict the use of the XID frame information field from defining other standard formats for use in specific applications.

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. The frame structure portion defines the relative positions of the various components of the basic frame format and the nonbasic frame format.
Mechanisms are provided to permit the general purpose XID frame information iso iec 13239 jec be used to negotiate private parameters in a single XID exchange simultaneously with negotiation of the defined basic iso iec 13239.
For the balanced connectionless class, the data link consists of two peer stations and operates in the balanced connectionless-mode in a point-to-point configuration. These HDLC elements of procedures are defined specifically in terms of io actions that occur on receipt of commands at a secondary station, a tributary station, a peer station, or a combined station. This Standard References Showing 6 of 6. Iso iec 13239 Standards Expert eic, simplifies and expedites the process for finding and managing standards by giving you access to standards from over standards developing organizations SDOs.
It is used to select a pair of operational link addresses when preassigned, system designated addresses are not known on an a priori basis; e.
