The number of supported end-user systems depends on whether you use a host
or structured subnetting. For more information, see Chapter 5,

When multiple end users are connected, they may opt to access different NSPs,
as illustrated on page 4-4. When all 18 DSL cards are used, the Hotwire DSLAM
can support simultaneous access up to 288 different NSPs or private intranets by
the end users (16 NSPs or private intranets per DSL card).
