Distinctive Ring	Distinctive ring is a service provided by local telephone companies that
Support	permits the assignment of multiple phone numbers to one line. Each
	phone number is associated with a different ring pattern, and devices
	that recognize distinctive ring, like the Business Modem, can be set to
	answer only on certain incoming ring patterns.
	For example, a fax machine, answering machine, telephone, and modem
	could all share the same line. Each device would have its own phone
	number and respond only to calls intended for that number.
