Standards

Summary

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.
