Information technology -- Telecommunications and information exchange between systems -- Private Integrated Services Network -- Mapping functions for the tunnelling of QSIG through IP networks
ISO/IEC 21992:2003(E) provides for two types of interconnection:
- on-demand, where a separate TCP connection for QSIG is established at the start of each call and cleared down at the end of that call; and
- semi-permanent, where a single TCP connection with an indefinite lifetime carries QSIG on behalf of many single calls.
ISO/IEC 21992:2003(E) is applicable to PINXs that can be interconnected to form a PISN using QSIG as the inter-PINX signalling protocol.
