There are several different methods available that allow access to the public Internet. Each has advantages and disadvantages. The number of PC’s, cost, availability, as well as the anticipated number of concurrent users, need to be factored into the decision process. While the final decision is the dealerships, a table is provided in Recommended Access Methods section to give some assistance in the selection. In order to avoid installation and connection delays, determine where the chosen access method will be terminated, as this point (demarcation) may need to be extended to a different location in the building.

Along with the primary public Internet access method, a primary backup method (usually connected to the router) with an ISDN or telephone line will allow for the continuation of business, but with an impact on performance. An alternate backup method is highly recommended in case of a major failure, such as a nonfunctional router. A dial-up connection from a stand-alone PC would allow access to the public Internet until the primary or the primary backup solutions are in place. The backup solution should be tested on a regular basis to ensure functionality in the case of a real outage. Since the Internet technology is changing at such a rapid pace, keeping the Internet access method contract to as short a term as possible is highly recommended. A month-to-month contract would be ideal and a two-year contract should be considered the maximum.
