The term describes modems that are used in broadband networks.
They are "high-speed" because they operate at relatively high bit rates
(200 Kbps or 1Mbps or perhaps higher), modulating an RF carrier up in
the high tens or hundreds of MHz.  They are "frequency-agile" because
they are able to operate on any one of a group of adjacent frequencies,
which gives the effect of several independent networks sharing the
same cable and a modem able to connect to any one of the networks
via software command.
