DSL broadband technology supplies significantly faster data transfer speeds than dial-up Internet, without a huge investment. It is a cost effective and convenient permanent connection.
What is DSL Broadband Technology?
Digital Subscriber Line (DSL) is a proven standard 'always on' alternative to Integrated Services Digital Network (ISDN) and other leased line options, with affordable installation and service costs. Simply installing DSL on your existing phone line and purchasing a DSL modem/router allows businesses of all sizes to access high speed broadband at a relatively low cost.
DSL refers to technology and equipment deployed on the existing copper wire telephone infrastructure to enable multi-channel, high speed access. The single twisted-pair phone line is converted to enable it to be used for high-speed data transmission, without disrupting the telephone signal.
Copper wire lines are designed to carry voice or modem signals of a frequency band up to 3.4 kHz, providing maximum data speeds of 56kbps. With broadband technology, higher data speeds are possible by utilising a broader range of frequencies. Each range of frequencies acts as a separate channel on the same copper wire to enable additional data to be transmitted, providing greater bandwidth availabilities for business applications.
Asymmetrical (ADSL) VS Symmetric (SDSL)
ADSL allows data to be transferred at different speeds: the downstream (downloading) data speeds are faster than upstream (uploading) data speeds.
SDSL allows data to be transferred at identical speeds both downstream and upstream with guaranteed throughput. For data applications needing high-upstream bit rates, such as Voice over IP, symmetric DSL delivers a fully inter-operable solution.
