| Summary: | Introduction/purpose: To specify the practical application of ECMA355 and ECMA-336 Standards for Q-SIG tunneling and the
implementation of mapping functions via the existing IP (Internet
Protocol) network of the Serbian Armed Forces (Intranet SAF), in
the Private Automatic Telephone Network SAF (PATN SAF), as
the main part of the Private telecommunication-information
networks of integrated services SAF (PISN SAF).
Methods: Description of the implemented solution and analysis of
the software parameters of the established transmission SIP route,
with the display of the results obtained in the fight with jitter and
echo in the network.
Results: With such a solution, it was achieved that participants from
the peripheral parts of the PISN SAF, which operate on the
principle of transmission and circuit switching by TDM (Time
Division Multiplexing), can connect with each other via the newly
established central IP network SAF (Core network) which operates
on the principle of transmission and switching packets with the SIP
(Session Initiation Protocol), without losing the functionality of QSIG from the framework of the digital telecommunication network of
integrated services ISDN (Integrated Services Digital Network).
Conclusion: The article deals with the modern IP PINX (Private
Integrated Services Network Exchange) manufactured by Mitel,
type MX-ONE Service Node 6.0, which is implemented at the
transit level PATN SAF and which successfully implements the
process of tunneling Q-SIG through the IP network and the
necessary functions for mapping the transmission of tunneled QSIG messages and mapping voice (and other audio) information to
VoIP (Voice over IP) communication media streams through that
network. Also, the basic elements for its software preparation
during the introduction of a new SIP route, with a capacity of 30 IP
trunks in a transmission beam realized with 100 Mb/s-T Ethernet,
are given, and the fight with the present jitter and echo in the
network is described. Finally, the paper presents the experiencebased values of the parameters for reducing the influence of jitter
and suppressing echo. |
