Configuring PPP connections
A PPP connection is a temporary WAN connection brought up by a remote device dialing into
the MAX. It is the most common type of WAN connection, and can be configured in a local
Connection profile or in RADIUS. The next sections contain examples of both types of
configuration.
A PPP connections can be one of the following types:
•
PPP—A single-channel connection to any remote device running PPP software.
•
Multilink PPP (MP)—A multilink connection to an MP-compliant device from any
vendor.
•
MP with Bandwidth Allocation Control Protocol (MP with BACP)—An MP call that uses
BACP to increase or decrease bandwidth on demand.
•
Multilink Protocol Plus (MP+)—A multilink connection, to another MAX unit that uses
dynamic bandwidth allocation (DBA) to increase or decrease bandwidth on demand.
Note:
MP+ supersedes MPP.
A multilink connection begins by authenticating a base channel. If the connection allows
additional bandwidth, the local or remote unit dials another link. For example, if a dial-in
Lucent Pipeline unit has a single-channel session at 56 Kbps or 64 Kbps and multilink PPP is
configured, a second call can combine the first B channel with the second for a transmission
rate of 112 Kbps or 128 Kbps.
MAX units can be stacked to distribute the bandwidth required for connections across multiple
units (as described in “Configuring a Combinet connection” on page 4-91).
Note:
If a connection configured for MP or MP+ fails to establish multiple channels, it falls
back to a single-channel PPP session. In either case, you can use the PPP parameters as part of
the connection negotiation. Use the MP, BACP, and MP+ settings in addition to the
single-channel PPP settings.
