Sigtran - SS7 Interface to Packet Training
ONSITE TRAINING
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.

What You Will Learn:

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 networks. 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.

Audience / Target Group

This course will be an invaluable tool for those individuals responsible for maintenance and surveillance of the voice, signaling, or IP (packet) networks. This is especially true for personnel working in a control center environment such as the NOC, INAC, ESAC, etc. Anyone responsible for maintaining services on the existing intelligent network platform would also benefit. Others would include network or traffic engineers, technical support, network planners and interconnection specialists.

Prerequisites

A basic knowledge of telephony, IP and signaling would be helpful, but not essential.
