scope:

This ETS specifies the full mechanical and electrical charateristics, the necessary functional characteristics and the corresponding conformance tests for a terminal equipment interface for: a) connection to the network termination points of 34 368 kbit/s digital unstrutured leased lines (D34U); and b) connection to the network termination points of 34 368 kbit/s digital strutured leased lines (D34S) which support an unstructured 33 920 kbit/s information transfer rate. These leased lines are defined in ETS 300 686 and ETS 300 687.
