Network
Group of devices. Devices can be connected in either wired or wireless mode.
Networks can also differ in range and structure:
– Range: local networks (LAN) or wide-area networks (WAN)
–Structure: Infrastructure network or ad-hoc network
Network subscribers
Devices and computers that are connected to each other in a network, e.g. servers, PCs
and phones.
O
Outbound proxy
Alternative NAT control mechanism to STUN and ALG.
Outbound proxies are implemented by the VoIP provider in firewall/NAT environments
as an alternative to SIP proxy server. They control data traffic through the firewall.
Outbound proxy and STUN servers should not be used simultaneously.
See also: STUNand NAT.
P
Paging (handset search)
A base station function to locate registered handsets. The base station establishes a con-
nection to every registered handset. The handsets start to ring. Paging is activated by
briefly pressing the button on the base station and is deactivated by briefly pressing the
same button again.
PIN
Personal Identification Number
Protects against unauthorised use. When the PIN is activated a number combination has
to be entered in order to access a protected area.
You can protect your base station configuration data with a system PIN (4-digit number
combination).
Port
Data is exchanged between two applications in a Network via a port.
Port forwarding
The Internet gateway (e.g. your router) forwards data packets from the Internet that are
directed to a certain Port to the port concerned. This allows servers in the LAN to offer
services on the Internet without you needing a public IP address.
Port number
Indicates a specific application of Network subscribers. Depending on the setting in
the LAN, the port number is permanently assigned or else it is newly assigned with each
access.
The combination of IP address/Port number uniquely identifies the recipient or sender
of a data packet within a network.
Pre-dialling
See Block dialling.
Private IP address
See Public IP address.
