ÖNORM EN 300001 V 1.5.1

This Access EN specifies the technical requirements (electrical, mechanical and method of signalling) and their associated compliance tests to be met by all TE at each of its ports provided for connection to the Public Switched Telephone Network (PSTN). This connection is effected at a standard analogue interface. This interface is characterised by a two-wire derived presentation using DC loop seizure and clear and low-frequency AC ringing signals below the speech passband. These requirements and associated compliance tests form the definition of the standard analogue PSTN access (Aspect 2) in each of the participating Administrations. It is recognised that for historical reasons requirements and their associated compliance tests may include values particular to each Administrations network. These requirements reflect existing standards. This access EN does not necessarily contain all the requirements which a specific type of TE shall meet in order to gain type approval for attachment to the relevant PSTN attachment point. 1.2 (BG) 1 The present document does not form the type approval requirements for equipment that contain certain call routing or certain switching functions, in these cases Bulgarian national requirements apply and reference shall be made to the Bulgarian Approval Authority in order to determine the totality of applicable requirements and associated tests. The present document is applicable for telecommunications systems in which the a/b input wires are switched galvanically to the extension lines. 1.2 (CZ) 1 The present document applies to Terminal Equipment (TE) connected to the analogue interface of the Public Switched Telephone Network (PSTN). It does not apply to mobile radiotelephony and terminal equipment for which technical specifications exist, e.g. public coin or card telephone equipment, shared subscriber lines, transmission and line-sharing subscriber equipment.
