Course Name:
SS7 Protocols
Course Length: 4 ½ days
Description: The
SS7 Protocols course provides an in-depth look at the structure and supporting
documents of this widely-deployed signaling protocol. A thorough understanding of its structure,
use and deployment is essential to anyone operating, managing or maintaining
the complex telephony network.
Emphasis is placed on underlying documentation that supports the
protocol’s structure and use in trunk setup and application services.

Many exercises are provided
throughout the course re-enforcing a practical understanding of the
material. This gives the student
practice in analyzing the SS7 protocol and understanding how the data being
sent and received is used.
What You Will
Learn: This
course will provide the structure of the protocol down to the binary
level. Emphasis is placed on giving the
student the ability to isolate and sectionalize troubleshooting in the Common
Channel Signaling (CCS) network. There
is also a thorough examination of the feature services that are deployed today
and how the network and the SS7 protocol support those services.
Who Will Benefit
From This Course: This
course will be an invaluable tool for those individuals responsible for
maintenance and surveillance of the voice or signaling network. Anyone responsible for maintaining services
on the intelligent network platform would also benefit. Others would include network or traffic
engineers, technical support and interconnection specialists.
Course
Prerequisites: A basic
knowledge of telephony and signaling would be helpful, but not essential.
