But what if your fax machine, too, could be smart enough? Then it could
ignore one of the two numbers, "knowing" that it's supposed to answer
only the other.
Well, as you've probably guessed by now, that's exactly what your fax
machine can do. All you have to do is give it a little help at the beginning
and begin to enjoy the benefits of its OneLine + distinctive ring detection
(DRD) feature.
In order that you may use OneLine + DRD, your phone company must set
up your distinctive ring service. When it does, it will assign a ring pattern,
expressed in time.
For example, the standard telephone ring is 2 seconds "on" (ringing) and 4
seconds "off" (silent), after which it repeats itself (hence the term, ring
pattern).
Some telephone companies provide only a very general description — for
example, "short-short-long" — of their DRD ring patterns. Fortunately,
however, your machine has eight possible distinctive ring patterns for use
with OneLine + DRD; one of them should work with your phone
company's DRD service.
This chart lists the patterns:
Pattern

B
C

For example, pattern C is 0.3 seconds ringing, 0.2 seconds silent, 1 second
ringing, 0.2 seconds silent, 0.3 seconds ringing and 4 seconds silent; then
it goes back to the first 0.3 seconds ring and starts over.
