Alarm of a telecommunications terminal connected to a LAN

摘要

It is advantageously taken profit of the fact that before any supply of remote power to a telecommunications terminal connected to a local area network, the Ethernet equipment must recognize the power class of said terminal by measuring a specific electrical signature of said terminal via their interconnection. In the case said Ethernet equipment will stand in a situation unable to supply the required power, then it will send a specific signal via said interconnection which will activate an alarm on said terminal. The possibility to be alerted by a specific alarm from said terminal in the case no remote power can be supplied to it, will advantageously inform the user of that terminal about the powering situation. This will prevent any confusion about the reason of a wrong running of that terminal and may allow to look for an alternative. <IMAGE>
