The NT1+2a/b is a network terminating unit with built-in terminal adapter for ISDN basic connections. The system realises the transition from the public ISDN network subscriber line to the private S-bus. The digital interface allows the operation of ISDN systems, telephones and PC cards. All services offered by the network operator are thus available to the subscriber. Up to eight ISDN terminals can be connected directly to the ISDN S-bus. In addition, the terminal adapter also provides the interfaces for conventional analogue terminals, such as telephones, fax machines or answerphones. For ISDN signaling, the NT1+2a/b provides two 64 kbps bearer channels and a 16 kbps data channel (a signaling channel which can also serve for data transmission). Two simultaneous external calls are possible, as is channel bundling, the use of both bearer channels.
