Ethernet card for connection to a local network, for controlling connection to a communication terminal
First Claim
1. An Ethernet card (CL) for connection to a local network (LAN), for a communication terminal (UE), where this terminal includes a first internal bus (PCI1) and first power means (MAP) capable of powering this terminal from a local power source, where the said card (CL) includes:
- a second internal bus (PCI2), coupling means (MCP), to couple the second internal bus (PCI2) to the first internal bus (PCI1), and second power means (MAA) capable of powering this card from a remote power source (PPP) located in the said local network (LAN);
characterized in that it also includes control means (MCC) for the coupling means (MCP), where these control means (MCC) are connected logically to the first (MAP) and second (MAA) power means, and arranged to command the said coupling means to electrically decouple the second internal bus (PCI2) from the first internal bus (PCI1), so as to allow operation of the card independently of the said terminal (UE) in the event of detection of the presence of a remote power source and the absence of a local power source.

Abstract
An Ethernet card (CL) is dedicated to the connection of a communication terminal (UE) to a local network via an Ethernet connection (CX). The terminal (UE) can be powered electrically by first power means (MAP), and includes a first internal bus (PCI1). The card (CL) includes i) second power means (MAA) capable of being powered remotely, via the Ethernet connection (CX), by power control means (PPP) on the local network, ii) a second bus (PCI2) coupled to the first internal bus (PCI1), iii) coupling means (MCP) coupled to the second bus (PCI2), and iv) control means (MCC) connected logically to the first (MAP) and second (MAA) power means and tasked, in the event of detection of remote powering of the card (CL) and the absence of electrical powering of the terminal (UE) by its first power means (MAP), to command the coupling means to electrically decouple the card from the first internal bus (PCI1), in order to allow its operation independently of the terminal (UE).
