signaling circuitry for providing channel communication, ground fault detection system and method of providing communication over a compromised communication channel

摘要

patent system: "system and method for securely communicating over a compromised communication channel of a network device". The present invention relates to a system and method for providing communication over a compromised communication channel in a system having a first node and a second node connected through the communication channel that is provided. for example, a signaling circuit may be provided. The signaling circuit includes a main signal electrically connected to the first and second portions of the communication channel. the first and second portions of the communication channel are employed on the first node. the signaling circuit further includes a slave signal processor arrangement coupled to the main signal processor arrangement and electrically connected to the third and fourth portions of the communication channel. the third and fourth parts of the communication channel are employed on the second node.
