NTBA Standard 2B1Q ISDN Network Termination

As network terminating unit for ISDN basic connections, theNTBA enables the transition from the public ISDN subscriber line to the private S-bus. The interface allows the connection of ISDN communication systems, ISDN telephones and ISDN PC cards, offering subscribers access to all the services provided by their network operator.

For ISDN signaling, the system 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 for the transfer of large amounts of data. The NTBA Standard comes with a wall-mounted casing. Power for all internal functions is supplied either by the exchange via the U-interface, or locally.
