DSL (Digital Subscriber Line)

Common Usage: Customers (typically individuals or small businesses) who simply want to use their existing phone lines for Internet connectivity. Must be within 18,000 feet of a central office.
Definition: A high-speed Internet connection delivering data over existing telephone lines at a transmission speed between 128Kbps-10Mbps.

DS1 (Digital Signal Level 1)

Common Usage: Customers (typically small to medium businesses) that need a high-speed Internet connection, multiple phone lines, or a combination of the two.
Definition: A service that provides a dedicated connection from your premises to a long distance switch, providing the user with a multi-channel, high-capacity digital circuit for voice and/or data applications. DS1 can be provisioned by channels for data, voice, or any combination up to 24 channels.

T1 (Trunk Level 1)

Common Usage: Customers (typically small to medium businesses) requiring high-speed Internet connections, point-to-point data transport customers, and multi-line voice capability.
Definition: A digital transmission link with a total speed of up to 1.544 Mbps. Mostly synonymous with DS1. A T1 Internet connection's cost is comprised of two parts: the local loop charge or the phone circuit that connects your location to the Internet point-of-presence (POP), and the actual Internet bandwidth access port charge.
