Chapter 13 Point-to-Point Protocol
GENERAL
The point-to-point protocol (PPP) provides a standard method of transporting
multi-protocol datagrams (a unit of transmission in the network layer such as
IP) over point-to-point links. PPP is a popular protocol standard used in the
equipment employed by many Internet access providers. The PPP feature
allows the 500 TA (in asynchronous mode) to connect with a remote synchro-
nous PPP device via the ISDN.
The Point-to-Point Protocol is designed for simple links which transport pack-
ets between two peers. These links provide full-duplex simultaneous bidirec-
tional operation, and are assumed to deliver packets in order. It is intended that
PPP provide a common solution for easy connection of a wide variety of hosts,
bridges and routers. PPP was implemented using RFC documents 1661 and
1662 from the Internet Engineering Task Force.
PPP can be enabled using the AT%A2 command using the following syntax:
AT%A2=95.
There are no other user selectable parameters directly associated with PPP.
Point-to-point protocol can be selected within the LocalMenu (AT@MENU)
menu structure in units so equipped.
NOTE: Bidirectional RTS/CTS flow control (\Q3) is the only flow control sup-
ported by the PPP protocol.
