Abstract: Each of a large number of geographically distributed call boxes asynchronously transmits unique code-identified digital messages for taxicab request, vanadalism alarm, low power, or on-line status by Frequency Shift Keyed Bi-phase Modulated radio. To ensure receipt of any simultaneous, conflicting, messages at a central receiver, each call box repeats transmission of its messages three times at intervals. For human-initiated taxicab requests the call box itself feeds back a "cab dispatched" visual indication to satisfy the requestor after a predetermined delay. However, this indication actually represents only a highly probable occurrence and is not generated in response to an actual dispatch at a central location. The centrally received messages are processed by digital computer to eliminate redundance, display requests to a dispatcher of service, an log all requests and responses thereto.

Abstract: An emergency call service system, such as an E911 system, provides service system personnel with the addresses of abandoned calls to facilitate abandoned call follow-up. When a call comes in to a "911" ANI controller (21), the calling number is recorded. If the call is abandoned prior to being assigned by ACD 23 to an agent position (27-28) for being answered, an abandoned call ALI function (25) is invoked to obtain information pertaining to the calling number from a database (20), similarly to a non-abandoned call. When obtained, the information is displayed on equipment (29) such as a printer, terminal, or PC, to make it available to system personnel for use in following up on the call. The ANI controller serves both "911" emergency calls and emergency call-handling agents as well as other calls and other users, by switching the emergency calls to the agents and switching the other calls to the other users.

Abstract: A central control unit (scanner) is connected across a set of subscriber loops. At each subscriber's premises, an individual subscriber terminal unit (STU) is connected across that particular subscriber's loop. To each STU are connected the various instrumentalities which are to be monitored by the system, e.g. fire alarms, burglar alarms, etc. FSK modulated signals in the upper part of the audible range are transmitted from the scanner to the STUs at appropriate times. The STUs reply by means of similar signals to indicate the status (e.g. alarm, or non-alarm) of the instrumentalities at the respective subscriber premises. This transmission and retransmission is interrupted when the subscriber's telephone is off-hook. In addition, a signal below the audible range (low tone) is produced at the STU, and transmitted to the scanner over the telephone loop when all the instrumentalities at the particular subscriber premises are in a given state (e.g. non-alarm).
