Private Integrated Services Network (PISN); Profile Standard for the use of PSS1 (QSIG) in Air Traffic Services networks

Scope

The present document 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.
The present document 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.
The present document states requirements upon implementations in order to achieve interoperability between equipment
in ATS PISNs.
NOTE 1: Implementation of the present document does not preclude a manufacturer from offering other means of
interconnection.
The present document does not specify requirements related to interworking between QSIG and other signalling
systems used in ATS PISNs.
