4.4.2. PPPoE Configuration
Point to Point Protocol (PPP) is one of standard protocol to send data through
the WAN link. RFC1661 describes PPP specifications. Not only in the
synchronous WAN (serial) line but also in the asynchronous WAN (dial up line,)
PPP can be used. Since PPP is a standard rules, it guarantees interoperability
among different manufacturers’ devices.
Nowadays PPP extended to not only Serial Line but also Ethernet and ATM Lines.
PPPoE(PPP over Ethernet) means PPP Protocol in the Ethernet Line.
VoiceFinder AP21200 Gateway can be installed under ADSL modem. In this
case, AP2120 supports PPP and the Ethernet Interface Ecapsulation is “PPPoE”.
PPP consists of two kinds of protocol as follows:
z Link Control Protocol (LCP): LCP decides the encapsulation format, limits
the packet size, performs authentication in the link, decides normal
operation time and breakdown time, detects loop-back link faults and
other faults, and automatically terminates the link.
z Network Control Protocol (NCP): NCP communicates with various higher
layer (network layer) protocols.
If a PPP encapsulation option is given to VoiceFinder AP2120 Gateway, PPPoE is
activated. Current software installed in the Gateway supports Challenge
Handshake Authentication Protocol (CHAP), the authentication option that
uses Password Authentication Protocol (PAP,) and the magic number
configuration option. The software always sends the magic number
configuration option, but sends the authentication option only when the
authentication option is set.
