What are the Various Types of xDSL?
There are several forms of PRIMUS xDSL, each designed around specific goals and needs of the customer. Below is a brief summary of some of the types of xDSL technologies used by PRIMUS. SDSL — Symmetric Digital Subscriber Line. SDSL provides bandwidth of up to 1.1 Mbps in both directions over a single copper phone wire. However, the bandwidth speed can be achieved only if the customer is less than 8,000 feet from the local phone company central office, though slower speeds are available out to 18,000 feet (3.5 miles). This central office must be DSL capable. IDSL — ISDN-based DSL. IDSL is DSL service run over existing ISDN lines. IDSL is often available where other DSL services are not available.
