Cabling system and method for monitoring and managing physically connected devices over a data network
First Claim
1. A method, comprising:
- in a cable connection, which comprises a first section comprising one or more wire pairs and having a first end that is potentially connected to a first endpoint, and which further comprises a second section comprising the one or more wire pairs and having a second end that is potentially connected to a second endpoint, applying a test signal to a single wire pair selected from among the wire pairs via one or more signal-injection impedance-components that are connected to the single wire pair at a mid-point between the first and second sections;
sensing the test signal on the single wire pair via one or more signal-sensing impedance-components that are connected to the single wire pair at the mid-point between the first and second sections; and
based on the sensed test signal, determining whether or not the first section is connected to the second section at the mid-point.

Abstract
The present disclosure relates to a method and system configured to monitor devices that are physically connected over a data network, said system comprising at least one scanner configured to monitor said data network and to determine devices that are physically connected over said data network, said at least one scanner being connected to at least one panel over said data network, wherein at least one terminal of each panel is connected to an electronic circuitry, which comprises one or more electronic components, for enabling said at least one scanner to determine changes in one of voltage or current level over at least one of said one or more electronic components, said changes occurring due to connecting or disconnecting devices over said data network, thereby enabling said at least one scanner to monitor devices that are physically connected over said data network.

6. A method, comprising:
-
connecting a network scanner to a cable connection, which comprises a first section comprising one or more wire pairs and having a first end that is potentially connected to a first endpoint, and which further comprises a second section comprising the one or more wire pairs and having a second end that is potentially connected to a second endpoint, wherein the network scanner is connected to the cable connection at a mid-point between the first and second sections by one or more signal-injection impedance-components and one or more signal-sensing impedance-components, while retaining Direct-Current (DC) connectivity between the first and second ends of the wire pairs; using the network scanner, applying a test signal to the cable connection via the signal-injection impedance-components at the mid-point between the first and second sections, and sensing the test signal on the cable connection via the signal-sensing impedance-components at the mid-point between the first and second sections; and based on the sensed test signal, distinguishing whether none of the endpoints, only one of the endpoints, or both of the endpoints, are connected to the cable connection. - View Dependent Claims (7, 8)
