Overview

Frame Relay is a public, connection-oriented packet service based on the core aspects of Integrated Services Digital Network (ISDN). Frame Relay eliminates all processing at the network layer and greatly restricts data-link layer processing.

To create Frame Relay on unchannelized modules, such as a T3-Frame module or an E3-Frame module, you must navigate through the following hierarchy:

• The module
• The line interface

For channelized modules, such as a CT3, CE1, or CT1 module, you must navigate through the following hierarchy:

• The module
• The line interface
• A DS1 interface
• A DS0 bundle
