DIA (Dedicated Internet Access) is connectivity from a customer's location to the Internet. DIA is comprised of two separate components: the local loop and the DIA port. The local loop is the actual connectivity from the customer's physical location to their DIA provider's POP. This loop can be ordered through their DIA provider or it can be a customer provided loop ordered through the customer's RBOC or LEC. The DIA port is literally the portal that allows for the Internet access.

With connection speeds ranging from 128Kbps on a T1 loop to a 2488 Mbps OC48, businesses can choose the speed and price point that best suits them.
Dedicated Internet can also be value added with features like domain and website hosting. For the service conscientious customer, an integrated T1 providing fractional Internet service with long distance access is available in many areas.
