摘要： An Interchangeable Standard Port or Stack Port (ISPSP) uses a standard physical connector such as an RJ-45 or SFP. The ISPSP automatically detects whether it is connected to a standard port, such as a 1000BaseT, or whether it is connected to another ISPSP stacking port. This automatic detection can be done through hardware or software. Once the auto-detection is complete the routing platform will automatically configure the ISPSP port for standard 1 Gbps bit rate and framing, or for stacking, e.g., 2.5 Gbps bit rate, and framing.

摘要： An apparatus and method for extending the range of a digital data network by enhancing skew control. The apparatus is a circuit for use in a network interface unit. The apparatus measures the distance of the network interface unit from the head-end retransmission unit of the network by transmitting a series of signal packets on the network and counting the time it takes for the packets to be received back at the interface unit. All transmissions on the network take place with reference to a timing mark transmitted by the head-end unit at a regular interval. The apparatus sends the first in the series of signal packets at a pre-determined pre-skew interval before the timing mark. The apparatus counts the number of clock cycles after the timing mark before the signal packet is received back at the network interface unit. If the signal packet is not received back at the network unit within a pre-determined number of clock cycles, the apparatus sends a new signal packet at a new, larger pre-skew interval before the timing mark and again counts the clock cycles after the timing mark. This process is repeated until a signal packet is successfully received back at the network interface unit. Once a signal packet is successfully received back at the network interface unit, the pre-skew value at which the packet was sent and the value of the number of clock cycles after the timing mark at which the packet was received back is stored in the interface unit and all subsequent transmissions by that unit on the network are done at an interval before the timing mark defined by the stored skew value.

摘要： A system for electric power demand monitoring and control includes one or more data distribution networks interconnecting intelligent utility units located at customer homes with a host computer located in the utility company offices. Each intelligent utility unit is associated with a customer home for connecting and disconnecting a power service meter, monitoring customer demand, and controlling power to selected units. A network within the home interconnects each intelligent utility unit with power consuming units for providing data on power usage and power control. A data distribution network interconnects the plurality of intelligent utility units to the host computer as a head end unit, the data distribution network providing downstream communication channels from the host computer to the plurality of intelligent utility units and upstream communication channels from the plurality of intelligent utility units to the host computer. The communication channels are organized as frequency division multiplex channels in a frequency spectrum. A plurality of distribution networks can be provided for a larger utility environment with each distribution network associated with a power substation and customers served by the power substation.
