Distinctive Ring

Distinctive Ring is a phone service that may be offered by your
phone company. Check your phone company for availability. With
this service, you can have several phone numbers assigned to the
same phone line. The phone company will send a different type of
ring signal for each phone number being called. The subscriber can
distinguish which number is called by which type of ring is received.
One benefit of this feature is the ability to have three numbers on
the same line allowing you to list the three numbers for voice, data,
and fax, respectively. You can then have your fax machine answer
only the ring corresponding to the fax number and have your
modem answer only the ring corresponding to the data number. A
voice call will not be answered by either fax machine or data
modem and it will only be answered when someone picks up the
phone. You can also have the answering machine answer only the
voice ring. A more complicated use is that you can have one
number for multiple uses, such as one number for both data and fax.
A ring signal is a composition of repeated on and off states.
Different types of rings usually correspond to different
compositions of the "ON" part (cadence) of the ring. Your modem
can distinguish up to four types of ring signals and can be
commanded to answer or not answer any one of these four types of
ring signals. Following is a list of these four types of ring signals.
These are the ring types used in the USA. The difference among the
