This course provides detailed instruction on how to configure and monitor the Cisco® ASR 5000 to function as a tunnel termination gateway (TTG) in a 3G Wi-Fi offload network environment. The TTG provides interworking between a wireless LAN (WLAN) and a 3G mobile packet core (MPC).

Upon completion of this course, you should have a thorough understanding of the following aspects of the platform:

• Performing basic service configuration and monitoring of the TTG.
• Monitoring the system for proper subscriber session establishment.
• Basic debugging of initial attachment failure.

• Day 1: Morning Session
