Configuration Concepts and Profiles
Overview of MAX configuration
Creating a network diagram
Lucent strongly recommends that, after you have read these introductory sections, you diagram
your network and refer to the diagram while configuring the MAX unit. Creating a
comprehensive network diagram helps prevent problems during installation and configuration,
and can help in troubleshooting any problems later.
Configuring lines, slots, and ports for WAN access
The MAX unit has four built-in T1 or E1 lines and a V.35 serial port (8 Mbps). Each T1 or E1
line has a wide variety of configuration options, including whether or not you use ISDN
signaling, the type of physical-layer framing, cable length, and telco options. The way you
configure each line affects how much bandwidth will be available and whether you can direct
outbound calls to use specific channels. The way you configure channels depends on your
connectivity needs.
Use the serial WAN port for a leased high-speed connection to a Frame Relay switch or to
another WAN router. The port itself requires little configuration. A Frame Relay or Connection
profile specifies most of the required information.
You can add expansion modules to support additional bandwidth (BRI lines), serial host port
modules to support videoconferencing, and digital modems to support analog modem
connections over digital lines. The lines and ports on the modules (cards) have their own
configuration requirements, including the assignment of telephone numbers and information
about routing calls.
Once you enable the lines, slots, and ports for WAN access, you need to configure the way in
which outbound calls are routed to them (for dial-out access to the WAN) and the way in which
inbound calls are routed from them to other destinations (such as the local network).
Configuring WAN connections and security
When the MAX receives packets that require establishment of a particular WAN connection, it
automatically dials the connection. Software at both ends of the connection encapsulates each
packet before sending it out over the telephone lines. Each type of encapsulation supports its
own set of options, which can be configured on a per-connection basis to enable the MAX to
interact with a wide range of software and devices.
After a connection’s link encapsulation method has been negotiated, the MAX typically uses a
password to authenticate the call. For detailed information about authentication and
authorization, see the MAX Security Supplement. Following are some of the connection
security features the MAX supports:
Feature Description
Authentication
protocols For PPP connections, the MAX supports both Password
Authentication Protocol (PAP) and Challenge-Handshake
Authentication Protocol (CHAP). CHAP is more secure than PAP, and
is preferred if both sides of the connection support it.
Callback security You can have the MAX call back any user dialing in to it, thus
ensuring that the connection is made with a known location.
