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.

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.
vendor.
•
MP with Bandwidth Allocation Control Protocol (MP with BACP)—An MP call that uses
BACP to increase or decrease bandwidth on demand.
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.
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.
