Overview
This course provides the student with knowledge of SS7oIP architectures
as well as a background in next generation telephony architectures. The
focus of the course is the SigTran protocols that enable C7/SS7
protocols to be run over IP networks; namely the SCTP, M2UA,
M2PA, M3UA, IUA, and SUA protocols. In addition
an overview of the ITU BICC protocol will be provided.
The course begins by covering architectural elements including Application
Servers, Virtual Switching Elements, Virtual Database Elements, Media
Gateways, Media Gateway Controllers, Signalling Gateways, and Routing
Keys. How these elements interact to provide signalling in an IP domain
is further detailed. After architectural coverage the functions and features
the SCTP protocol is provided. The C7/SS7 related SigTran protocols are
then individually presented including the functions provided by each protocol
layer and seamless C7/SS7 message transmission to an IP domain.
Required background information, technical standards, including network architecture, and call models are detailed. |
Prerequisites
The course assumes that the delegates have basic familiarity with signalling system #7 (C7/SS7), basic telecommunication and datacommunication concepts. |
