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.
