  • Patent number: 6959006
    Abstract: A service delivery unit for an enterprise network is provided. The service delivery unit includes at least one network interface port that is coupleable to a wide area network and at least one data port that is coupleable to a plurality of local area networks. The service delivery unit also includes a policy server interface that is coupleable to a policy server. The policy service includes policies for bandwidth allocation stored on a computer readable medium. The service delivery unit further includes a central processing unit that is communicatively coupled to the network interface port, the data port and the policy server interface. The central processing unit executes instructions to selectively allocate bandwidth in the wide area network for users of the plurality of local area networks based on the policies stored in the policy server.

  • Patent number: 6847609
    Abstract: A telecommunications network is provided. The network includes at least one service delivery unit having a data port and a network interface port and a memory that stores data for managing the telecommunications network. The network interface port is coupled to a switch fabric. The data port is coupleable to at least one local area network. A network management station is communicatively coupled to the service delivery unit. The at least one service delivery unit is configurable to allow the network management station to view selected portions of the data in the memory of the at least one service delivery unit to facilitate management of selected aspects of the service delivery unit.

  • Patent number: 3941936
    Abstract: A telecommunications system using TDM principles for signalling and speech path usage plus PAM principles for speech transmission. Each function circuit such as a trunk, link or register, etc. is allocated a basic time slot or channel for initiation of its function when indicated. The active period of each function circuit is continued during the period of three succeeding time slots. In this way, up to four function circuits or channel units may be active during a finite period of time.In the system, a line is scanned at the end of each complete scan of all channels, thereby lessening the complexity of associating a line and a function circuit. The system shown uses the dual highway principle for its speech path and provision is made in each line circuit for switching onto both highways.
