7.7 - ADSL

ADSL, or Asymmetric Digital Subscriber Loop, is a data connection not intended for connection to a voice switch. It provides a computer network link to a user's PC via a NIC, Network Interface Card. Facilities are usually included to allow a voice call to be made at the expense of bandwidth.

The primary use for the service will be to provide SOHO and private users permanent access to the Internet by using their current copper pair phone line connection with a device similar to an ISDN Terminal Adapter. This device will also provide a voice connection so that calls can still be made and received over the service.
