ÖNORM EN 300248 V 1.2.1

The present document specifies the physical and electrical characteristics (except safety, overvoltage and EMC aspects) and corresponding test principles for a terminal equipment interface for connection to the network termination points of ONP 2 048 kbit/s digital unstructured leased lines using 120 OHM interfaces. The present document is to ensure that the interface of the terminal equipment is compatible with the ONP 2 048 kbit/s digital unstructured leased line. It is applicable to all interfaces designed for connection to the leased line, however in the cases of apparatus that carries a particular service, of complex apparatus and of apparatus in private networks, other requirements may apply in addition to the present document. Customer premises wiring and installation between the terminal equipment and the Network Termination Point (NTP) are outside the scope of the present document.
