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
es
to
. 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
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
to
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.
