DECT
Digital Enhanced Cordless Telecommunications
Global standard for wireless connection of mobile end devices (handsets) to telephone base
stations.
DHCP
Dynamic Host Configuration Protocol
Internet protocol that handles the automatic assignment of IP address es to Network
subscriber . The protocol is made available in the network by a server. A DHCP server can, for
example, be a router.
The phone contains a DHCP client. A router that contains a DHCP server can assign the IP
addresses for the phone automatically from a defined address block. The dynamic
assignment means that several
Network subscriber s can share one IP address, although
they can only use it alternately and not simultaneously.
With some routers you can specify that the IP address for the phone is never changed.
Display name
PABX feature. You can specify any name that is to be shown to the other party during a call
instead of your phone number.
DMZ (Demilitarised Zone)
DMZ describes a part of a network that is outside the firewall.
A DMZ is set up, as it were, between a network you want to protect (e.g., a LAN) and a non-
secure network (e.g., the Internet). A DMZ permits unrestricted access from the Internet to
only one or a few network components, while the other network components remain secure
behind the firewall.
DNS
Domain Name System
Hierarchical system that permits the assignment of IP address es to Domain name s that are
easier to memorise. This assignment has to be managed by a local DNS server in each
(W)LAN. The local DNS server determines the IP address, if necessary by enquiring about
superordinate DNS servers and other local DNS servers on the Internet.
You can specify the IP address of the primary/secondary DNS server.
See also: DynDNS .
Domain name
Name of one (of several) Web server(s) on the Internet. The domain name is assigned to the
relevant IP address by DNS.
DSCP
Differentiated Service Code Point
See Quality of Service (QoS) .
DSL
Digital Subscriber Line
Data transfer technology that allows Internet access with e.g., 1.5 Mbps over a conventional
telephone line. Prerequisites: DSL modem and the appropriate service offered by the
Internet provider.
