This National Standard of Canada is equivalent to International Standard ISO 8822-1988. It defines (in an abstract way) the externally visible service provided by the OSI Presentation Layer in terms of: a) the primitive actions and events at the user/service boundary; b) the parameter data associated with each primitive action and event; c) the relationship between, and the valid…

Specifies details for types of threads and thread sizes. Tabulates nominal diameters from 9,73 mm up to and including 30 mm together with the corresponding pitches and designations, refers to the national standards of concern (table 1). Table 2 contains valve outlets for toxic gases; valve outlets for flammable gases are given in table 3. Table 4 gives valve outlets for oxidizing gases, and table…

This National Standard of Canada is equivalent to International Standard ISo 7776-1986. 1. Scope and field of application This International Standard defines an application of the following HDLc Standards: ISO 3309, ISO 4335, ISO 7478, and ISO 7809. When there is difficulty in the interpretation of a reworded requirements from one of the other International Standards, the original…

This National Standard of Canada is equivalent to International Standard ISO 7478-1987. 1 Scope and Field of Application This International Standard specifies multilink procedures where a multiplicity of parallel data links at the data link layer are used to provide a variable bandwidth data link between network layer entities. The multilink procedures (MLP) exist as a new upper sublayer…

This National Standard of Canada is identical in content and in layout with International Standard ISO 8208-1987, Information processing systems - Data communications - X.25 Packet Level Protocol for Data Terminal Equipment. It specifies the procedures, formats and optional user facilities at the Packet Level for Data Terminal Equipment (DTE) operating in conformance with CCITT…

This National Standard of Canada is equivalent to International Standard ISo 3309-1984. 1. Scope and field of application This International Standard specifies the frame structure for data communication systems using bit-oriented high-level data link control (HDLC) procedures. It defines the relative positions of the various components of the basic frame and the bit combination for the…

This National Standard of Canada is equivalent to International Standard ISo 4335-1987. 1 Scope and field of application This International Standard specifies elements of data link control procedures for synchronous, code-transparent data transmission using the HDLC frame structure specified in ISO 3309 and independent frame numbering in both directions. These HDLC elements of…

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…

This National Standard of Canada is equivalent to International Standard ISO 8471-1987. It is applicable to data stations employing HDLC balanced classes of procedures which provide the XID command/response capability.

This National Standard of Canada is equivalent to International Standard ISo 8885-1987. 1. Scope and field of application The principal use of the XID frame is to exchange data link information between two or more HDLC stations. For the purpose of this International Standard, data link information shall include any and all essential operational characteristics such as identification…
