  • Patent number: 11431842
    Abstract: Techniques are described for managing out of service telephone numbers (TNs) before returning them to active service. A telephone number profile score may be calculated for an out of service TN entering an aging protocol, the aging protocol comprising a pre-determined number of days the TN must remain out of service. The out of service TN may then be assigned a profile based on its telephone number profile score, the profile indicative of how quickly the TN will achieve one or more quality thresholds. The number of days from entry into the aging protocol it will take the TN to achieve the one or more quality thresholds based on its assigned profile may be determined. The quality threshold status of the TN may then be updated each time it crosses one of the quality thresholds. Once it completes the aging process, the TN may be placed into an inventory of TNs eligible for active service.

    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.

    Abstract: An apparatus includes a DSL transceiver configured to transit to a DSL wait state in which a power transmitted from the DSL transceiver to a local-end line is substantially reduced in response to an interruption or substantial stop at the DSL transceiver of reception of DSL communications from the local-end line. The DSL transceiver is configured to transmit to the local-end line a DSL acknowledge signal in response to receiving from the local-end line a DSL wait signal. The DSL transceiver is configured to resume to transmit DSL communications to the local-end line at a power substantially higher than the power transmitted thereto in the DSL wait state in response either to receiving from the local-end line DSL transmissions at a substantially higher power than received there from in the DSL wait state or to receiving from the local-end line a second DSL acknowledge signal.
