sDSL offers 1.5 Mbps at a much lower price than T1 service. Whats the difference between these two products?
Not all customers can receive 1.5 Mbps SDSL service, but all customers in serviced Central Offices can receive T1 Service. Because of technical limitations of the DSL protocol, only those customers less than 10,000 feet from their CO can receive 1.5 Mbps SDSL. However, T1s are engineered to extend tens of miles, so almost all customers of a serviced CO can purchase T1 service. In addition, the local exchange carrier will remove bridge taps, load coils, and splices from the wiring when provisioning a T1; they wont do this for a DSL circuit.
