This 2-3 day Hands-On training course is designed for telephone company employees responsible for engineering and provisioning Special Circuits. This training provides in-depth training of special circuits currently used, the theory behind each type, design requirements, and actual equipment used in the Central Office, outside plant and the customer premise.
This course provides the required foundation, understanding and Hands-On skill set for any technician in a special Circuit environment.
Anyone entering the telephone communications industry.
None. A basic understanding of telecommunications principles will be useful for students taking this course. This information can be obtained in our
