What is G.DMT wires-only?
G.DMT is a ratified standard defining a common interface for ADSL modems. G.DMT ‘wires-only’ ADSL was launched as a product in January 2002 by BT Wholesale. This allows users/ISP’s to use DSL modems that they themselves have purchased, as oppossed to the Alcatel USB and Effecient 5861 that were previously supplied by BT on the IPStream500/S products. Wires-only is also referred to as ‘self-install’ because there is no need for a BT engineer to visit at install time. Instead, a microfilter needs to be purchased and fitted to every phone socket of the line with ADSL to filter out the Data from the Voice frequencies.
