Describes the requirements for standard serial data interfaces in alarm transmission systems. Gives an outline of how alarm transmission systems are connected and the various types of serial data interfaces that might be employed.

Spécifie les exigences pour les interfaces de données série normalisées des systèmes de transmission d'alarme. Indique la manière dont les systèmes de transmission d'alarme sont connectés et les différents types d'interfaces de données série qui peuvent être utilisés.

Specifies the requirements for standard interfaces using a two-wire connection employing ISO/IEC 8482 signalling for use between the control and indicating equipment of an alarm system and one or more alarm system transceivers connected to alarm transmission systems.

Deals with protection against lightning of outdoor telecommunication lines using metallic conductors (for example, access networks, lines between buildings). These lines concern: - telecommunication lines connecting a switch with a network termination (NT1) - telecommunication or signal lines connecting equipment located in different buildings, e.g. ISDN lines or signal lines between computers.…

Traite de la protection contre la foudre des lignes de télécommunication extérieures utilisant des conducteurs métalliques (par exemple réseau d'accès, lignes entre bâtiments). Ces lignes sont : - les lignes de télécommunication connectant un commutateur avec le réseau terminal (NT1); - les lignes de télécommunication ou de signaux connectant divers bâtiments, par exemple des lignes ISDN ou…

Is a guide for assessing the reliability of all types of fibre-optic interconnecting devices and passive optical components. It applies to passive devices for connection, branching, switching, minimization of reflection, control of power/attenuation, dispersion compensation, modulation and wavelength selection or filtering.

This National Standard of Canada is equivalent to International Standard ISO/IEC 8480:1995. 1 Scope This International Standard specifies the procedures for back-up operation applicable to data transmission on a leased line when implemented through a single interface, controlling both the leased and the back-up facilities, using ITU-T Recommendation V.24 interchange circuits in…

This National Standard of Canada is equivalent to International Standard ISO/IEC 8481:1996. 1 Scope This International Standard describes an arrangement for interconnection of Data Terminal Equipment (DTE), without intermediate Data Circuit-terminating Equipment (DCE), in terms of electrical, mechanical, and functional characteristics. This International Standard applies to DTEs with…

This National Standard of Canada is equivalent to International Standard ISO/IEC 14474:1998. 1 Scope This International Standard is a part of the functional requirements for the Private Integrated Services Network (PISN) and defines the functions and procedures that are required by Private Integrated Services Network exchanges (PINXs) and the intervening network (IVN) in order to…

This National Standard of Canada is equivalent to International Standard ISO/IEC 15050:1997. 1 Scope This International Standard specifies the signalling protocol for the support of the Advice Of Charge supplementary services (SS-AOC) at the Q reference point between Private Integrated Services Network Exchanges (PINX) connected together within a Private Integrated Services Network (PISN…
