  • Predictively allocated bandwidth in a communications network
    Patent number: 7254130
    Abstract: In a broadband communications network, bandwidth is allocated to bearer channels for a circuit connected service, such as narrowband telephony. The allocated bandwidth is changed automatically as a function of time so as to track expected changes in demand for bearer channels. When the number of allocated channels falls from its peak value, then at the access node some of the channels may be marked as blocked.
