Broadband Enabling Technology (BET) is a overlay to existing DSL technology. To get BET to work BT install a BET line card in the exchange and a remote unit in the street cabinet (PCP) and a Network Termination Unit (NTU) at the customers home.
BET has been developed by BT Openreach to provide broadband services to locations that currently have no broadband connection or very limited speeds due to their distance from the local telephone exchange. BET helps to turn these “Not Spots” into “Yes Spots”, by providing 1Mbit/s or 2Mbit/s broadband services over lines much longer than were previously possible.
BET is a network enhancement capability which enables or improves customer’s broadband service on long lines (where the line loss is greater than 55db). BET utilises an existing tried and tested Digital Subscriber Line (DSL) technology platform (Symmetric Hi-Speed Digital Subscriber Line (SHDSL)). Achievable line speed using BET would be up to 1 or 2 Mbps. 2Mbps service requires an additional copper pair.
The following telephone exchanges listed below have just been enabled for BET :-
