  • Patent number: 8830878
    Abstract: Techniques are described for better ensuring that calls or transmissions directed to a subscriber or endpoint to which a number was previously assigned are not received by a new subscriber or endpoint. According to one class of implementations, a telephony platform maintains a registry that associates a secondary identifier with each phone number that is currently assigned to a subscriber. The identifier may point to and/or include any of a variety of information that maps to the current subscriber. When a calling party initiates a call to an assigned number, an additional identifier is transmitted with the call routing information that corresponds to the entity or endpoint to which the call is directed. The telephony platform makes call routing decisions based on the correspondence of this information with the information maintained in the registry.

The translations database maintains translations for its associated remote terminal special number calls, including, but not limited to, 9-1-1 calls. When the call control system recognizes a special number call, it performs a look up in its translation database using the line ID as a key and substitutes a destination number for the special number and a calling line telephone number for the line ID. The call control system forwards the call to the local switching office, which treats the call as a trunk-to-trunk call. Advantageously, one (or more) trunk of the trunk group may be reserved solely for special number calls.

A system incorporating teachings of the present disclosure may include an interface that receives a signal associated with a call to a telephone number. A call information engine may be coupled to the interface and may recognize that a party to the call subscribes to an enhanced call activity service. In some cases, the party may be a called party or a calling party, and the activity may include an incoming call to the telephone number, an outgoing call, a missed call, or a waiting voicemail message. A memory may maintain a data network address for the party, and a messaging engine may initiate sending of a message containing call information to the data network address. The message may be sent in response to a trigger signal output by a notification engine without consideration for whether or not a telephone line associated with the telephone number is busy.

  • Publication number: 20120288067
    Abstract: Systems and methods are provided for assigning a customer device to a group of customer devices for the transmission of broadband data signals. A communications signal output by a customer device associated with a customer of the service provider may be received by a service provider system. The service provider system may be associated with the service provider, and the service provider system may include one or more computers. The received communications signal may be processed by the service provider system to determine a linear impairment associated with the customer device. Based at least in part on the linear impairment, a frequency range at which communications will be output by the service provider system for receipt by the customer device may be determined.

  • Patent number: 8290123
    Abstract: A method run in a gateway for detecting a communication link between a called telephone and a telephone switch is provided. The method firstly detects if a ringer equivalency number (REN) is equal to zero. If the REN equals to 0, the method further determines if each discharge curve of a positive wire and a negative wire of the called telephone complies with a corresponding standard discharge curve, so as to determine if the communication link between the called telephone and the telephone switch has been established.

  • Publication number: 20120207285
    Abstract: A method for providing clean endpoints including managing a collection of endpoints; testing communication of an endpoint of the collection of endpoints; and generating a cleanliness score for the endpoint according to results of the test. The method functions to create a metric that can be used to evaluate undesired communication activity and functionality of an endpoint. The method may be implemented by any suitable platform providing endpoint addresses to clients, which may include service providers, internet-telephony platforms, or any suitable entity. The method is preferably applied to telephony endpoints used in internet-telephony applications, but may be used in any suitable application.

  • Patent number: 8165271
    Abstract: A system and method is described that allows a system operator to remotely detect and diagnose a voice-enabled cable modem that has entered a chattering line state so that appropriate steps may be taken to avoid or rectify any of the problems that may result from this condition. Logic within the voice-enabled cable modem monitors for pulse dialing activity and/or excessive hook state and/or flash events that may be attributed to a faulty telephone and/or telephone line connected to the voice-enabled cable modem. Responsive to detecting such conditions, the logic within the voice-enabled cable modem reports a fault condition to an external management system via a cable data network.

    Abstract: A system and method of telephony resource management and security for monitoring and/or controlling incoming and outgoing calls between an enterprise's end-user stations and a public circuit-switched network and/or a public packet-switched network. A security policy is made up of one or more rules designating at least one action to be performed based on at least one attribute of the incoming or outgoing call. Calls are detected and sensed on the line, trunk and/or cabling, and analyzed to determine attributes associated with each call. Actions are performed based upon the determined attributes, in accordance with the security policy rules.

  • Publication number: 20110261932
    Abstract: A FDR SELT measurement is made in a stop band of a DSL band plan, using a PSD allowed by the PSD mask. Further measurements may also be made in an adjacent pass band and further bands, and the results combined to create a wide-band measurement result. When transformed into the time domain (e.g. by inverse Fourier transform to produce the line impulse response) greater resolution in time (and hence greater spatial resolution) is achieved. In order to compensate for AGC calibration errors measurements using different AGC steps may be scaled to fit smoothly to each other. If measurements overlap, measurement results in the region of overlap may be combined in various ways to limit the influence of noise and to create a smooth transition from one measurement to the next.

  • Patent number: 8009808
    Abstract: A call control system comprising a control module, a translations database and a switching fabric are connected to a trunk group between a remote terminal and its controlling local switching office. The call control system monitors control signals from the switching office on the trunk. In the event of loss of control signals, the call control system intercepts requests for service, etc. from a calling telephone connected to the remote terminal and performs a look up in the translation database. If the call can be completed without the controlling switching office the call is looped back to the remote terminal. The translation database is maintained by a remote terminal OA&M interface that receives change orders from the local exchange carrier. The remote terminal OA&M interface forwards relevant changes to the call control system's translation database.
