ATM Signaling

Introduction

ATM signaling protocols vary by the type of ATM link, which can be either UNI signals or NNI signals. UNI is used between an ATM end system and ATM switch across ATM UNI, and NNI is used across NNI links. ATM signaling uses the one-pass method of connection setup that is used in all modern telecommunication networks, such as the telephone network.
