Course Name:
SIGTRAN (SS7 Interface to Packet)
Course Length: 2 days
Description: The
SIGTRAN 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.
Telecom Training Associates will
provide each student with a high-quality workbook and all of the necessary
supplies.
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.
Who Will Benefit
From This Course: 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.
Course
Prerequisites: A basic
knowledge of telephony, IP and signaling would be helpful, but not essential.
Instructors: All of our instructors have
years of experience developing and teaching technical courses at Telcordia
Technologies (Bellcore) Learning Services in Lisle, IL.. They are all CompTIA CTT+ Certified
Professionals and SS7 certified.
