The
http://en.wikipedia.org/wiki/Bit_rate of consumer DSL services typically ranges from 256 kbit/s to over 100 Mbit/s in the direction to the customer (
http://en.wikipedia.org/wiki/Downstream_(networking)), depending on DSL technology, line conditions, and service-level implementation. Bit rates of 1 Gbit/s have been reached in trials,
http://en.wikipedia.org/wiki/Digital_subscriber_line#cite_note-1 but most homes are likely to be limited to 500-800 Mbits. In ADSL, the data throughput in the
http://en.wikipedia.org/wiki/Upstream_(networking) direction (the direction to the service provider) is lower,
hence the designation of asymmetric service.I'd like to know "is used" has been omitted after "service."
Thank you in advance for your help.
