[Acronym] for __A__symetric __D__igital __S__ubscriber __L__ine.

A technology that uses the frequencies above human hearing to send data at high speed to the exchange (a technique also known as FrequencyDivisionMultiplexing, or BroadBand). It's limited in range, the closer you are the faster the top speed you can get, up to 8mbit downstream.  (The maximum distance is dictated by the [Interleaving]). It's Asymetric because the upstream and downstream rates are different, upstream being much lower than downstream.  Much of this is academic however, as most [ADSL] providers have capped your bandwidth anyway although [TelecomNZ] are changing this.  You'll need a special [ADSL] modem to use [ADSL], and need special equipment at the exchange.

Because [TelecomNZ] owns most of the LocalLoop in NewZealand, you can only get consumer [ADSL] that is provided by them and resold. They used to call it JetStream but now call it [Xtra] BroadBand. Customers on TelstraClear's network can get a product that used to be called [Tempest] but is now imaginatively called High Speed Internet. This shouldn't be confused with the one they resell which they call PDQ (Pretty Damn Quick) BroadBand.
