Abstract: A method of simulating a telecommunications network may include providing a database including status information for a plurality of virtual network elements. More particularly, the status information for each of the plurality of virtual network elements may include a respective network element identifier. A communication including a received network element identifier may be received. If the received network element identifier does not correspond to a network element identifier included in the database, status information for a new virtual network element may be added to the database and the status information for the new virtual network element may include the received network element identifier. After adding the status information for the new virtual network element, a communication regarding the new virtual network element may be transmitted. Related systems and computer program products are also discussed.

Abstract: A system and method for providing simultaneous ringing service to a plurality of customer premises equipment. The method and system utilize a centralized database of subscriber information and a service node to make multiple outbound calls from the service node to multiple telephone lines assigned to a subscriber. The subscriber's telephone lines may include one or more wireless lines. Inbound calls to the subscriber's primary wireline are intercepted by the simultaneous ringing service and forwarded to the service node for processing.

Abstract: Apparatuses, methods, and systems for identifying a target location to an occupant are provided. The apparatus comprises a laser rotatably coupled to a body of the apparatus, and at least one sensor connected to the body. The at least one sensor is configured to detect an alarm, and when the at least one sensor detects the alarm, the laser is configured to emit a laser beam to indicate a target location to an occupant. The method for identifying or indicating a target location comprises detecting, by a sensor of an apparatus, an alarm, in response to detecting the alarm, outputting, by the sensor, a signal, in response to the signal, activating a laser rotatably coupled to a body of the apparatus to identify or indicate the target location. The invention may be used for emergency situations to indicate a target location such as an exit for occupants of a building or residence.

Abstract: Calling plan information is provided whenever a user makes a call that fits within the plan. The user may be assigned an account related to the calling plan with information associated with the account. The information may include a time function such as the time remaining until expiration of the calling plan or the time used in the calling plan. A call made from an originating number that is associated with the calling plan triggers the provision of information. After the information is provided, the call may be routed to a terminating number as dialed by the user. After the call, the information associated with the calling plan may be updated.
