Die Annotation des Normtextes ČSN ETSI EN 300132-2-V2.5.1 (872006):
V2.5.1 The present document contains requirements and measurements methods for the physical interface that is situated between the power supply system(s) and the power consuming telecommunications and datacom (ICT) equipment; this point is called interface "A" as defined in clause 4. The purpose of the present document is to use a power supply system with the same characteristics for all telecommunications and datacom (ICT) equipment defined in the area of application: - to facilitate inter working of different (types of) load units; - to facilitate the standardization of telecommunications and datacom (ICT) equipment; - to facilitate the installation, operation and maintenance in the same network of telecommunications and datacom (ICT) equipment and systems from different origins. The present document aims at providing electrical compatibility between the power supply equipment and the power consuming telecommunications and datacom (ICT) equipment, and also between different system blocks connected to the same power supply. The requirements are defined for: - the output of the power supply equipment or power supply installation of telecommunications centres providing power at the interface "A"; - the power supply input of any type of telecommunications and datacom (ICT) equipment installed at telecommunication centres that are connected to interface "A" powered by DC; - any type of telecommunications and datacom (ICT) equipment, installed in access networks and customers´ premises, the DC interface "A" of which is also used by equipment requiring a supply to the present document. - any type of telecommunication and datacom (ICT) equipment powered by DC, used in the fixed and mobile networks installed in different locations as building, shelter, street cabinet. Disturbances on the power supply interface "A" relating to the continuous wave phenomena below 20 kHz are covered within the present document. The present document does not cover safety requirements, they are covered by relevant safety standards. The present document does not cover EMC requirements, they are covered by relevant EMC standards. NOTE 1: The present document is applicable only to -48 VDC power supply interfaces. However, during a transitional period, other DC voltages may be used in existing installations. Annex B gives guidance on working in conjunction with existing -60 VDC supply systems. NOTE 2: The DC voltage at interface "A" may be derived from the AC primary supply. The DC supply may incorporate a backup batter
