Passphrase
Used much like a password, a passphrase simplifies the WEP encryption process by
automatically generating the WEP encryption keys for the company products.
POE
Power over Ethernet. A standard to deliver both power and data through one single
Ethernet cable (UTP/STP). It allows network device to be installed far away from power
ource. A POE system typically compose of 2 main component: DC Injector (Base Unit)
and Splitter(Terminal Unit). The DC injector combines the power and data, and the splitter
separates the data and power back. A PoE Access Point or CPE has the splitter built-in to
the device. The IEEE 802.3af is a POE spec that uses 48 volt to deliver power up to 100
meter distance.
Port
This word has 2 different meaning for networking.
z The hardware connection point on a computer or networking device used for plugging
in a cable or an adapter.
z The virtual connection point through which a computer uses a specific application on a
server.
PPPoE
Point-to- Point Protocol over Ethernet. PPPoE relies on two widely accepted standards:
PPP and Ethernet. PPPoE is a specification for connecting the users on an Ethernet to the
Internet through a common broadband medium, such as a single DSL line, wireless device
or cable modem.
PPTP
Point-to-Point Tunneling Protocol: A VPN protocol developed by PPTP Forum. With
PPTP, users can dial in to their corporate network via the Internet. If users require data
encryption when using the Windows PPTP client, the remote VPN server must support
MPPE (Microsoft Point-To-Point Encryption Protocol) encryption. PPTP is also used by
some ISP for user authentication, particularly when pairing with legacy Alcatel / Thomson
ADSL modem.
