Configuring WAN Connections
Link encapsulation
1-2 Preliminary January 30, 1998 Pipeline User’s Guide
This chapter explains how to set up the Answer and Connection profiles. A
profile is a group of settings that define the attributes needed to set up or answer a
call. You can define multiple Connection profiles and one Answer profile.
Connection profiles are used for both incoming and outgoing connections. The
Answer profile supplies general setup information that can be used to reject or set
up a connection if there is no Connection profile matching the caller’s settings.
The first Connection profile is automatically created when you set the parameters
in the Configure menu, which is described in the Start Here booklet.
Link encapsulation
One of the main agreements between the caller and the answering device must be
the type of link encapsulation used. The caller must encapsulate all outbound
packets before sending them across the WAN, and the answering device must
unencapsulate them before forwarding the packets to the local network.
Following are the types of link encapsulation supported by the Pipeline:
Method Connection description and attributes
PPP Point-to-Point Protocol (PPP), is a single-channel connection that
connects to any other device running PPP.
PPP connections support password authentication using Password
Authentication Protocol (PAP), Challenge Handshake
Authentication Protocol (CHAP), and Microsoft CHAP (MS-
CHAP).
They can support IP routing, IPX routing, or protocol-independent
bridged connections.
They can be dial-in or dial-out switched connections.
MP Multilink PPP (MP) call using two channels. This type of
connection uses PPP to initiate the call and to add a second
channel. Once the second channel is connected, it is used for the
duration of the call. It is not as flexible as MPP or MP+.
