To send data to all computers on a network.
Central Office A circuit switch that terminates all the local access
lines in a particular geographic serving area; a physical building
where the local switching equipment is found. xDSL lines
running from a subscriber's home connect at their serving central
office.
Dynamic Host Configuration Protocol
address assignment and management. When a computer
connects to the LAN, DHCP assigns it an IP address from a
shared pool of IP addresses; after a specified time limit, DHCP
returns the address to the pool.
Dynamic Host Configuration Protocol relay. A DHCP relay is a
computer that forwards DHCP data between computers that
request IP addresses and the DHCP server that assigns the
addresses. Each of the My ADSL Modem's interfaces can be
configured as a DHCP relay. See DHCP.
Dynamic Host Configuration Protocol server. A DHCP server is a
computer that is responsible for assigning IP addresses to the
computers on a LAN. See DHCP.
Of data, having a form based on discrete values expressed as
binary numbers (0's and 1's). The data component in DSL is a
digital signal. See also analog.
Domain Name System. The DNS maps domain names into IP
addresses. DNS information is distributed hierarchically
throughout the Internet among computers called DNS servers.
When you start to access a web site, a DNS server looks up the
requested domain name to find its corresponding IP address. If
the DNS server cannot find the IP address, it communicates with
higher-level DNS servers to determine the IP address. See also
domain name.
A domain name is a user-friendly name used in place of its
associated IP address. For example, www.globespan.net is the
domain name associated with IP address 209.191.4.240. Domain
names must be unique; their assignment is controlled by the
Internet Corporation for Assigned Names and Numbers
(ICANN). Domain names are a key element of URLs, which
identify a specific file at a web site, e.g., http://
www.globespan.net/index.html. See also DNS.
To transfer data in the downstream direction, i.e., from the
Internet to the user.
Digital Subscriber Line A technology that allows both digital data
and analog voice signals to travel over existing copper telephone
lines.
