A technology for bringing high-bandwidth information to homes and small businesses over ordinary copper telephone lines. xDSL refers to different variations of DSL, such as ADSL (asymmetric DSL), SDSL (symmetrical DSL), HDSL (high bit-rate DSL) and VDSL (very-high-bit-rate OSL). Assuming the location is close enough to a telephone company’s central office, one may be able to receive data at rates 500-800 Mbps downstream and potentially up to 1 Gbps.
