Abstract: A local exchange (10) includes a logic device (28) for producing a specified ring control signal pattern. The logic device (28), which is coupled to receive a calling information signal, produces a plurality of ring patterns according to the state of a caller ID blocking signal transmitted within the calling information signal. The logic device either examines the state of a specified signal or the character set of a caller ID field to determine whether to generate a different or standard ring control signal to cause a different or standard ring pattern to occur. A method includes setting a ring signal for a specified on time and resetting the ring signal for a specified off time in various combinations to create the unique ring patterns. In one embodiment, a common or standard ring pattern is used whenever a caller ID is not blocked and a different ring pattern is used when the caller ID is blocked.
