Digital Private Network Signaling System
Digital Private Network Signaling System ( DPNSS ) is a standardized signaling protocol in telecommunications for networking telephone systems . DPNSS was originally developed by British Telecom and described in the BTNR 188 standard . From 2001 the standard was continued as ND1301 by the "Network Interoperability Consultative Committee".
The networking of telephone systems is usually done with manufacturer or system-specific protocols. With these proprietary protocols , almost the full range of the features of the telephone systems can also be used across locations, within the corporate network formed with the networking . The networking of telephone systems from different manufacturers is only possible at a lower level (e.g. dialing numbers and speaking) without a common protocol. DPNSS was developed so that systems from different manufacturers with the extensive performance features can be networked with each other. Later, in competition with this, the European Telecommunications Standards Institute (ETSI) standardized the QSIG protocol.
