scope:
This European Telecommunication Standard (ETS) specifies the full physical and electrical characteristics and corresponding test principles for a terminal equipment interface for connection to the network termination points of Open Network Provision (ONP) ordinary quality or special quality voice bandwidth 4-wire analogue leased lines defined by ETS 300 451 and ETS 300 452. This ETS is not written for regulatory purposes.
This ETS is written only to ensure that the interface of the terminal equipment is compatible with the ONP ordinary quality or special quality voice bandwidth 4-wire analogue leased line. It is applicable to all interfaces designed for connection to these leased lines, however in the cases of apparatus that carries a particular service, of complex apparatus and of apparatus in private networks, other ETSs may apply in addition to this ETS.
Customer premises wiring and installation between the terminal equipment and the Network Termination Point (NTP) are outside the scope of this ETS.
