broadband terminal equipment (B-TE)
The term Broadband Terminal Equipment (B-TE) refers to the specification for terminal equipment in B-ISDN. Like B-NT (Network Termination) and B-TA (Terminal Adapter), B-TE was defined as a functional group in addition to the reference point R in Broadband ISDN.
The B-ISDN terminal equipment (B-TE) fulfills, among other things, the functionalities for the interfaces and the protocol between user-user and user- system. B-TE supports the transmission interface and associated Layer 1 functions, the protocol for signaling, call setup and termination to other terminals, and the OAM functions, Operation, Administration, and Maintenance (OAM).
There are two different terminal equipment definitions, the B-TE1 and the B-TE2.
A B-TE1 type terminal equipment is a system that meets the specifications for interfaces at the T (B) and S (B) reference points in B-ISDN. Type B-TE2 terminals do not comply with the ITU specifications for B-ISDN interfaces at reference points T (B) and S (B).
