Configuration Concepts and Profiles
Using the MAX as an ISP or telecommuting hub
Figure 2-1 shows a typical ISP configuration with three POPs. Each POP has at least one MAX
on an Ethernet LAN that also includes another Internet router, which could be, for example, a
Lucent GRF 400 router.
Figure 2-1. Using the MAX as an ISP hub
Typically, the MAX has T1 or E1 lines that use ISDN signaling to connect to the WAN and
handle the incoming switched connections. To connect to Internet routers, the MAX most often
uses the local Ethernet network, but the connections between Internet routers can be any high
bandwidth connection, such as Frame Relay, nailed T1, nailed E1, HSSI, FDDI, or Sonet.
Large ISPs often support redundant MAX units and Internet routers on each Ethernet segment.
Using the MAX as a telecommuting hub
Telecommuters are typically at branch offices, at home, at customer sites, at vendor sites, or on
the road. The MAX enables these remote users to access the corporate backbone just as though
they were connected locally. The backbone might be a NetWare LAN, an IP network, or a
multiprotocol network. Figure 2-2 shows an example in which home users, remote offices, and
customer sites can access the backbone network.
