Business TeleCommunications (BTC); 34 Mbit/s Digital Leased Lines (D34U and D34S); Terminal Equipment Interface
| Organization: | ETSI |
| Publication Date: | 1 January 1996 |
| Status: | inactive |
| Page Count: | 32 |
scope:
This ETS specifies the full mechanical and electrical characteristics, the necessary functional characteristics and the corresponding conformance tests for a terminal equipment interface for:
- connection to the network termination points of 34 368 kbit/s digital unstructured leased lines (D34U); and
- connection to the network termination points of 34 368 kbit/s digital structured 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.
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 34 Mbit/s digital unstructured or structured leased line. This ETS 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 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.
