What is SDSL?
SDSL. It’s only four little letters, but what a difference those four letters can make for an emerging business. SDSL is a high speed Internet access service that offers up to 30 times the speed of standard dial-up access. Symmetric Digital Subscriber Line (SDSL) is the latest high speed technology that uses your existing copper telephone wires to provide high speed Internet access at equal uploading and downloading speeds. Our SDSL takes existing voice cable that connects customers’ premises to the phone company’s central office (CO) and turns the line into a high speed digital link. SDSL is the perfect solution for small- to medium-sized businesses and home offices.
Symmetric digital subscriber line (SDSL) is a modem technology that allows data to be sent over existing copper telephone lines at higher speeds than traditional 56k dial-up connections. SDSL supports data rates up to 3Mbps, over 50 times faster than 56k. SDSL is called symmetric because it supports the same data rates for upstream and downstream traffic. This contrasts to asymmetric digital subscriber line (ADSL), which has lower data rates for upstream traffic. ADSL is more popular for residential users, as it allows normal telephone service over the same wire, and is usually less expensive than SDSL.
