The CTR 8740 is the industry’s first microwave router. It is a fully integrated microwave networking solution, delivering a unique combination of high capacity all-packet transport, Carrier Ethernet, IP/MPLS and PWE services and comprehensive mission critical microwave features. The CTR is purpose-built for microwave, enabling operators to prepare for the all-IP future.

The CTR8740 Installation, Operation and Maintenance course teaches students key functions of the CTR8740 platform. The course includes an overview of all available modules and the chassis, initial setup, install and login, basic configuration with the CLI, system commissioning, configuration, diagnostics, maintenance and troubleshooting. Extensive hands-on labs (nearly 50% of the course duration) and case studies offer students with scenarios they will face in real deployments in their networks.

Courses are conducted by AVIAT expert trainers in a mentoring environment backed by their deep technology expertise and experience in implementation of microwave wireless and IP networks.
The CTR8740 Installation, Operation and Maintenance course is conducted at the Aviat Training locations or can be arranged at customer sites.
