Each entry consists of a list of parameters that
represents the configuration of an VDSL modem.
When `dynamic' profiles are implemented, a default
profile will always exist. This profile's name will
be set to `DEFVAL' and its parameters will be set
to vendor specific values, unless otherwise specified
in this document.
When `static' profiles are implemented, profiles
are automaticly created or destroyed as VDSL
physical lines are discovered and removed by
the system. The name of the profile will be
equivalent to the decimal value of the line's
interface index.
