TONEX's 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.
Objectives
After attending this course, you will be able to:
Understand the basics of PSTN
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
Understand basics of Q.921/Q.931, MTP2/MTP3, SCCP and user parts
Describe SS7 over IP signaling transport mechanisms
Describe the key components in the SIGTRAN architecture
List basics SIGTRAN protocols
Understand SCTP, IUA, M2UA, M2PA, M3UA, TUA, TALI, SUA
