scope:

The present document is a part of a multipart document. It specifies basic compatibility and interoperability aspects, including basic transmission, which are applicable to all Terminal Equipment (TE) intended to be connected to analogue interfaces of public or private, switched or non-switched telephone networks. The present document is applicable to a TE which is capable of accessing an analogue telephone network line at the Network Termination Point (NTP).

The present document specifies the connection arrangements (plug or socket, of the supplier's choice) to be provided by the TE. Any connection/mechanical/wiring adapter that may be required between the terminal and the existing NTP is outside the scope of the present document.

The present document is intended to ensure that no harm occurs to the network.
