    摘要： In a broadband cable data network (10), a method and system for automatically allocating network resources such as IP addresses to control access to the network utilizes at least one DHCP server (12), and a common network database formed from a LDAP directory (22) for storing respective user configuration parameters, hardware address registration, and current binding information. A DHCP server (12) can add new hardware address registrations to the LDAP using an 'unregistered' service class. The DHCP server sends a DHCP reply tailored for unregistered devices, such as by allocating a privately-allocated IP address with no Internet access, or an IP address for a self-provisioning web server. A DHCP server views IP address allocation as having a short duration. Thus, if the IP network configuration does not change, user terminal will continue to receive the same allocated IP address due to the DHCP server's perception of an indefinite lease. The consistency of the IP addresses simplifies many operational concerns about dynamic addresses, such as minimizing DNS (domain name service) hostname updates, mapping IP addresses to user terminals during security incidents, etc.

    摘要： An apparatus and a method for simultaneously transporting telephone signals and broadband signals on a single coaxial cable (204). The ring line and tip line of the telephone signals are dc coupled onto the inner (212) and outer (214) conductors of the coaxial cable, while the information wire and reference ground of the broadband signal are ac coupled onto the inner and outer conductors of the coaxial cable respectively. Low pass filters at each end of the coaxial cable pass the telephone signal in and out of telephone jacks while blocking the broadband signals. High pass filters at each end of the coaxial cable allow the broadband signals to pass in and out of coaxial connectors while blocking the telephone signals. The coaxial cable is isolated from earth ground to prevent shorting of the telephone electrical power to earth ground. A ground block may be added to connect the reference ground of the incoming broadband signal to earth ground. The ground block may include surge suppression to protect the information wire of the incoming broadband signal.
