In one embodiment, estimating a length of a network connection, determining whether the estimated network connection length deviates from a predetermined threshold range, modifying one or more signal characteristics when it is determined that the estimated network connection length deviates from the predetermined threshold range are provided.

Extended reach data network

According to one embodiment of the invention, a method for providing redundancy for a card in a chassis includes providing first and second cards in a chassis. Each card has an output node connected to a common bus and a respective input node. The method also includes providing a facilitator card in the chassis. The facilitator card includes an input node connected to the common bus and an output node connected to the input node. The method further includes connecting the input node of the second card to the output node of the facilitator card and connecting the input node of the first card to the associated output node of the first card. This couples the input node of the first card to the input node of the second card to provide redundancy for the first card.

A system for managing data communication between physical layer devices and ATM layer devices in a cell based ATM network is disclosed. A plurality of low speed physical layer devices a high speed physical layer device are connected to a bus. A bus interface device is coupled to the bus, the low speed physical layer devices, and the high speed physical layer device. The bus interface device is operable to provide equal opportunities to access the bus to any connected physical layer device. An arbiter is coupled to the low speed physical layer devices, the high speed physical layer devices, and the bus interface device. The arbiter is operable to provide the high speed physical layer device with disproportionately frequent access to the bus.
