scope:
This TBR specifies the attachment requirements 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 term "attachment requirements" in the context of this TBR describes the essential requirements for access which have to be fulfilled under the Second Phase Directive (91/263/EEC). Conformance to these requirements does not guarantee end-to-end interoperability.
This TBR is applicable to all interfaces designed for connection to the ONP 2 048 kbit/s unstructured leased line. It covers the essential requirements for the physical and electrical characteristics of the terminal equipment interface.
Customer premises wiring and installation between the terminal equipment and the Network Termination Point (NTP) are outside the scope of this TBR.
