High Performance Three-Port Switch for Managed Ethernet Systems
First Claim
1. A communication system comprising:
- a first network device including a first and second port;
a second network device including a third port;
a first cable connecting the third port with the first port; and
a second cable connected to the second port,an isolation switch configured to isolate the first and second cables from each other;
a control module configured to control the isolation switch such that the isolation switch establishes connectivity between at least;
the first port and the second port, orthe control module and the first port or the second port; and
a network manager configured to manage the control module.

Abstract
A method and apparatus for isolating and analyzing segments of a deployed, operational cable plant from a remote location. Individual cables, or segments, within an operationally deployed cable plant infrastructure may be isolated and analyzed without requiring a technician to physically inspect and perform an on-site analysis. The approach allows a cable segment to be isolated and analyzed without physically disconnecting the cable from the deployed infrastructure. By isolating and analyzing selected cable plant segments, an entire deployed cable plant infrastructure may be discretely analyzed and specific problems within the cable plant infrastructure may be identified. The approach allows the analyses to be performed from a remote location and is compatible with and may be integrated within a multipurpose network management system.

15. A network device comprising:
-
first and second sets of ports; isolation switches; and a control module configured to control the isolation switches such that at least one isolation switch establishes connectivity between at least; one of the first set of ports and one of the second set of ports in a default configuration of the isolation switch, or the control module and one of the first set of ports or one of the second set of ports while isolating the one of the first set of ports from the one of the second set of ports. - View Dependent Claims (16, 17, 18, 19, 20)

21. A patch panel comprising:
-
a first and second set of ports disposed on oppose faces of the patch panel; isolation switches; a control module configured to control the isolation switches such that at least one isolation switch establishes connectivity between at least; one of the first set of ports and one of the second set of ports in a default configuration of the isolation switch, or the control module and one of the first set of ports or one of the second set of ports while isolating the one of the first set of ports from the one of the second set of ports in a test; and a management port through which the control module is able to communicate with a network manager. - View Dependent Claims (22, 23, 24)
