This Profile Standard specifies the combination of base standards, together with the selection of appropriate options and parameter values, necessary to specify how QSIG / PSS1 can be used to provide digital signalling capabilities between Private Integrated services Networks eXchange (PINX) in an Air Traffic Services (ATS) PISN.
This Standard defines:
- physical and electrical characteristics (physical layer) of the interfaces to the transmission systems to be employed;
- data link layer procedures to ensure error-free communications links;
- network layer procedures for call establishment and clearing; and
- supplementary services to meet specific ATS requirements.
This Standard states requirements upon implementations in order to achieve interoperability between equipment in ATS PISNs.
NOTE – Implementation of this Standard does not preclude a manufacturer from offering other means of interconnection.
This Standard does not specify requirements related to interworking between QSIG and other signalling systems used in ATS PISNs.
