Course Number

Course Duration
3 days
Course Description
Signaling Transport (SIGTRAN) course provides a comprehensive
understanding of the SIGTRAN architectural and technology.
SIGTRAN (Signaling Transport) over IP is a working group within the
IETF standard organization and it was developed to allow an
interworking between SS7 network elements and IP based
elements. Its primary purpose is to address the transport of
packet-based public switched telephone network (PSTN) signaling
over IP networks, taking into account the functional and
performance requirements of the PSTN signaling.
The course will cover major aspects of SIGTRAN with in depth
information, example implementations, case studies, and practical
guidance to give your team members a running start.

Understanding the basics of IP networks
Understand the basics of transport signaling such as
integrated service digital line (ISDN) (e.g. Q.931) or SS7 (e.g.
ISDN user part (ISUP), SCCP, and so on) messages between IP
nodes such as a signaling gateway (SG), a media gateway
controller (MGC), a media gateway (MG), or an IP–based
database
