The present invention includes systems and methods for detecting a speed limit violation based on the movement of a cell phone in a moving vehicle. The system and method determine whether a speeding violation has occurred based periodic cell phone location data, the time between a cell phone's presence at one location and the next, and the speed limit of the section of a section of road that the cell phone could be located on. Embodiments of systems and methods of the invention detect whether a moving vehicle may be part of a public transit system, in which case the corresponding cell phones are removed from consideration. The system and method also include generating a speeding ticket for a car determined to have violated a corresponding speed limit, keeping a record of a speeding violation, and sending a request to settle the ticket if it is not paid on time. Also included in the invention are embodiments of systems and methods that detect whether a cell phone moving in a car is in engaged in a call, and if so, generating a ticket for a driving-while-talking violation.

A backpressure mechanism uses a TDM backpressure bus with each port card being assigned time slot. During its time slot, each ingress card / port writes on the bus the number of packets it transmitted to an egress ports during the last data refresh cycle. This information is read by the egress ports and used to compute current depth of the switch fabric output queues. In addition to information received from ingress cards, egress cards keep count of number of packets received from the appropriate switch fabric port and based on it estimate / calculate the current depth of the switch fabric output queue. Congestion states are calculated for all queues by comparing the queue depth with a respective threshold. Each egress card uses these congestion states to generate backpressure signals to ingress cards. Ingress card are using these signals to make decision whether to send or not traffic to destination egress card / port.

A method of managing proactive maintenance tasks for a communication system. The method includes storing proactive maintenance tasks and searching the tasks using at least one search criteria. Deletion of a proactive maintenance tasks is permitted if the proactive maintenance task has not been sent to a technician dispatch module which dispatches proactive maintenance tasks to technicians. Exclusion of proactive maintenance tasks is permitted if the proactive maintenance task has been sent to the technician dispatch module.

Methods and systems for proactively maintaining a telephone system local loop. One embodiment includes acquiring at least one type of information selected from information from a Dynamic Network Analyzer or information from a Loop Facilities and Control System. Another embodiment includes communicating with a communications network and acquiring at least one type of information selected from the group consisting of customer information associated with copper line pairs and service information associated with copper line pairs. Still another embodiment describes a system including software modules communicating with a communications network. Software modules include a Dynamic Network Analyzer module and a Loop Facilities and Control System module. A database interfaces with the Dynamic Network Analyzer module and with the Loop Facilities and Control System module. A processor is also included, and the processor is capable of processing information stored in the database and of generating proactive maintenance.
