SS7 Interface To Packet Training

Duration: 2-3 days


The SS7 Interface to Packet course provides an understanding of how the SS7 protocol is transported over packet networks using IP. It details the family of protocols that provide reliable datagram service and user layer adaptations for the SS7 protocol. This protocol was originally intended to allow new VoIP networks the ability to easily interconnect with legacy PSTN networks and utilize the services that customers need and expect.

Exercises are provided throughout the course, re-enforcing a practical understanding of the material. ENO will provide each student with a high-quality workbook and all of the necessary supplies

This course starts by giving the student a thorough overview of the structure of the SS7 protocol and how it used today. Knowledge of SS7 is essential to thoroughly understand the Sigtran family of protocols. It then details how a suite of protocols known as Sigtran adapts the SS7 layers for transport over packet-based etworks. Emphasis is placed on the most significant protocol defined by the Sigtran group – the Stream Control Transmission Protocol (SCTP). Each Adaptation Layer – M2PA, M2UA, M3UA and SUA – are then detailed
