TCP/IP Networking for CPE Troubleshooting Technicians
Course Description
The Internet Protocol Suite, commonly known as TCPIP, forms the basis for the Internet and the next generation of telecommunications services. Once technicians understand how they work the next key skill for them to learn is how to analyze and troubleshoot faults. Some services will be delivered and installed by a single organization. TCPIP and Internet services by their very nature must interface to customer networks and PCs. To function correctly both network service provider equipment and customer devices and networks must be configured to interoperate correctly.

This course will teach the systematic approach to troubleshooting and locating faults. Using practical hands-on course exercises technicians will learn what the impact is of likely faults implemented on test configurations within the classroom. Using recognized test tools they will then practice locating and the faults and fixing them.
Students Will Learn
Attendees should understand basic computer skills and be familiar with networking concepts, or have some working experience.
