Embodiment Construction

[0021] The approach disclosed herein can be used in any environment where a device, such as a media converter, must determine which of multiple communication lines to assign to an input port. If there are only two communication lines, the communication line assigned to the input port can be deduced by the process of excluding the remaining line to be assigned to the output port. According to one embodiment, the solution is implemented by a media converter. Furthermore, the scheme disclosed herein can be used to determine which of any number of communication lines to assign to an input port. For purposes of illustration, the scheme is described as being used to select from two pairs of communication lines within an RJ-45 jack.

[0022]A scheme in which a media converter can determine which of a plurality of communication lines is allocated to an input port of the media converter is outlined as follows. A switch is provided between a plurality of communication lines and a physi...

Abstract

A scheme by which a network device may be made to locate data signals from a plurality of potential data sources in the context of a network environment having devices that employ autonegotation overan autonegotiation period. The scheme involves switching an input port on the network device between the various potential data sources on a one-by-one basis. If an idle signal indicating no ensuing autonegotiation period is detected, the switching action is terminated and the input port assignment is maintained for as long as the link is detected. Thereafter, the device returns to the switching state. If an idle signal indicating an ensuing autonegotiation period is detected, the switching action is stopped for a period equal to or longer than the autonegotiation period. Thereafter, if an idle signal is detected, the input port assignment is maintained for as long as the link is detected.

Description

technical field [0001] The present invention relates generally to a network device usable in a communication network, and more particularly to a network device, such as a media converter, capable of being used for communications at speeds including 10 and 100 megabits per second (Mbs) Adaptive between network devices in the network. Background technique [0002] Communication networks are usually composed of different communication media. For example, unshielded twisted-pair wire (copper wire) can be used as a communications medium for transmitting data over relatively short distances, such as within a local area network in a small office environment. However, to transmit data over longer distances, data is usually sent via optical fiber. For example, multimode fiber can support data communication of 300-500 meters, while single-mode fiber can support data communication of several kilometers or even hundreds of kilometers. [0003] In many cases, it is necessary to connec...
