Out-of-Band Signaling

The out-of-band signaling class is designed to introduce the SS7/C7 and ISDN signaling protocols to students who already have a solid understanding of basic IPAX applications. When the class is over, students should be able to setup and trouble shoot ISDN FAS and NFAS signaling as well as SS7/C7 A-Link and F-Link configurations. The class consists of the following modules:

Introduction

Option and Port Licensing
Inband signaling overview
Inband signaling advantages and disadvantages
