【 摘 要 】

Introduction/purpose: The article should specify the network signalingtype Q-SIG, which is standardized especially for implementation indigital telecommunication networks of integrated services (ISDN),emphasizing the possibility of its further application in the PrivateTelecommunications Network of Integrated Services of the SerbianArmed Forces (PISN of SAF), i.e. in the Private Automatic TelephoneNetwork of the Serbian Armed Forces (PATN of SAF).Methods: An analysis of the existing standards was performed: ECMA355 and ECMA-336 and a synthesis of the possibilities of theirapplication in the PATN of SAF.Results: The procedure for the application of Q-SIG is processed in asituation when the peripheral parts of the PISN of SAF, which operateon the principle of transmission and circuit switching by TDM (TimeDivision Multiplexing), are connected via a central Core network withthe IP (Internet Protocol), which operates on the principle of packettransmission and switching with the SIP (Session Initiation Protocol). Amethod of the application of the tunneling of encapsulated Q-SIGmessages through the IP network, defined by ECMA-355 Standard,has been developed. The necessary functions for mapping thetransmission of tunneled signaling messages Q-SIG and mappingvoice (and other audio) information to media streams during VoIP (Voice over IP) communication through that network, which are definedby ECMA-336 Standard, are described.Conclusion: The application of ECMA-355 and ECMA-336 Standardsis a new solution in the PATN of SAF with the use of the IP network toconnect the IP PINX using the Q-SIG tunneling procedures andmapping functions for their transmission and transmission of audiosignals. This then opens up a whole range of new possibilities that,with the growth of the Core network and their application, will rapidlycontribute to the creation of a broad Telecommunication informationsystem backbone for the implementation of real-time multimediacommunications and the transition to Unified Communications (UC).
