Port forwarding

In port forwarding, the Gigaset SX763 WLAN dsl directs data packets from the Internet

that are addressed to a particular Port to the corresponding port of the appropriate net-

work component. This enables servers within the local network to offer services on the

Internet without them needing a Public IP address.

PPPoA

Point-to-Point Protocol over ATM

PPPoA is a Protocol for connecting network components in a local Ethernet network to

the Internet via an ATM network.

PPPoE

Point-to-Point Protocol over Ethernet = Point-to-Point Protocol over Ethernet

PPPoE is a Protocol for connecting network components in a local Ethernet network to

the Internet via a modem.

Private IP address

The private IP address (also known as the local IP address) is a network component's

address within the local network (LAN). The network operator can assign any address

he or she wants. Devices that act as a link from a local network, such as the Gigaset

SX763 WLAN dsl, have a private and a Public IP address.

Protocol

A protocol describes the agreements for communicating in a network. It contains rules

for opening, administering and closing a connection, as well as in relation to data for-

mats, time frames and possibly troubleshooting. Communication between two applica-

tions requires different protocols at various levels, for example the TCP/IP protocols for

the Internet.

PVC

Permanent Virtual Circuit

A permanent virtual circuit is a logical connection in an ATM network.

QoS

Quality of Service

QoS allows network traffic to be sorted according to priorities. When this parameter is

activated, Internet telephony is given priority over other data traffic. This is a precondi-

tion for problem-free calls.
