NGN Voice Protocols

3 Days / 5 Live Online Sessions (0900-1230) / Technical Level: Level 3

Course Code: TY1202

Course Summary

This course is intended for experienced telecoms engineers that wish to understand the workings of the protocols that are commonly used within Next Generation Networks (NGNs). The course takes a detailed look at real time signalling and transport protocols; it also looks at the protocols used to support legacy devices in the access and core network signalling such as POTS, ISDN and SS7. The course also looks in detail at the protocols supporting the new gateway devices. The course is backed up by an extensive set of exercises and the use of Wireshark.
