I'm far from a real phone company wizard, but tip and ring are
phone company terms.  If you want to connect them to your system
you need to go through a modem or equivalent for DS3/DS1/DS0.

Basically, that level of the phone company is concerned about
frequency rather than time.  If I understand things correctly
(which may be bogus), you get frequency without any way to connect
it back to a time-stamp.  (which is fine if you are a phone company)

These are my opinions, not necessarily my employer's.  I hate spam.
