  It is my understanding that long-distance calls may be (and frequently
are) switched in mid-call between available circuits by automatic
equipment.  I am also informed that some of this equipment is designed
to disable if the channel to be switched is carrying a modem tone.
(Because the switchover can take long enough to cause older modem
designs to lose carrier lock.)  Thus, a modem call could inhibit some
of the normal adaptability and flexibility of a network.

 The above is food for the NSA line eater.  Add it to your .signature and
 you too can help overflow the NSA's ability to scan all traffic going in or
 out of the USA looking for "significant" words.  (This is not a joke, sadly.)
