Glossary
keep-alive packets
Keep-alive packets are sent from both the client and server when no user data is
being transmitted. When one side of the connection fails to receive packets, a
notification is sent to indicate a disconnected peer. These packets also maintain an
active firewall state.
L
LCP echo request
An LCP echo request is a packet sent from a client-side controller to a server-side
controller to signal if a PPP link is still available. PPPD stops if LCP echo requests are
not received by the server. LCP echo requests are sent only if LCP is enabled.
line buildout
Line buildout refers to the length of the cable (in feet) that is connecting the devices
on each end of a T1 line or the level of attenuation (in decibels) required for the
devices on each end of a T1 line to communicate. Buildout is usually specified by
cable length for shorter connections and by level of attenuation for longer
connections.
linemode
Linemode is the type of hardware connection of an asynchronous link. There are two
values for linemode: RS232 and RS422. RS232 is a set of standards that specify the
type of interfaces connected to an asynchronous controller. The three types of
interfaces are electrical, functional, and mechanical, which are used for
communicating to computers, terminals, and modems. RS422 is a standard that
defines a balanced interface that does not accompany a physical connector.
local identity
The local identity is supplied by the local site and sent to a remote device. The identity
is similar to a user name for CHAP and PAP authentication on a point-to-point
connection.
