| ADSL-based Broadband |
Technology
Overview
BT's core network infrastructure is digital and carries massive amounts of
information - voice and fax calls, commercial data, emails and internet
traffic - quickly on optical fibre connections. But the ordinary telephone
line between the home or office and the local telephone exchange is
generally made of copper cable which carries the same information much more
slowly.
Digital Subscriber Line (DSL) technologies increase the speed and volume of
information that can be sent to the home of office, allowing customers to
download and experience web pages, graphics, music, video and text in
realtime.
Asymmetric DSL (ADSL)
BT offers an asymmetric DSL service - ADSL - which particularly suits the
needs of home and small business users. ADSL splits the standard telephone
line into separate channels for voice and data so you can make and take
calls even when you are online.
With ADSL, downloads run faster than uploads, which suits surfing the
Internet and downloading music and information. Other DSL services more
suited to business use are also available.
ADSL can only offer broadband data speeds where the telephone line between
the home or office and the telephone exchange is a maximum of 5.5km - just
over three miles - long.
Requisites for ADSL broadband:
|
1:) | You need to have a BT telephone line that is no longer than 5.5km - just
over three miles - to the exchange. |
|
2:) | The local telephone exchange needs to have been
enabled for ADSL.
(Spilsby requires another -17 registrations of interest from local residents before
this will happen) |
|
3:) | An ADSL modem/router - your existing dialup modem
will not work with an ADSL broadband service. |
