News from Colorado
The Denver Dispatch Company began telephone service in Denver in 1879. With 161 customers (including the Rocky Mountain News), this was the 17th exchange in the nation to open, and was one of the largest in the world at that time. The Colorado Telephone Company earned a reputation as being one of the best run of all the AT&T-owned operating companies. The Colorado Public Utilities Commission is looking at amending its telecommunications rules to reflect competitive changes in the industry. The PUC look at issues such as whether there is effective competition from wireless, cable and Voice over Internet Protocol providers across the state to warrant further deregulation of telecom services. Each telecommunications provider serving Colorado customers must apply for and receive a Certificate of Public Convenience and Necessity (CPCN) and a Certificate of Operating Authority to operate in Colorado. The PUC provides oversight over entry and exit from the Colorado market for telecommunication services with the goal of protecting customers from unscrupulous companies and assuring that companies provide service to customers on a non-discriminatory basis. Issuing CPCNs increases public confidence in the companies authorized to provide telecom services in the State. This promotes financially healthy companies who will stay in business and provide a high level of service to their customers.
