Abstract:
A method and apparatus for the detection and communication of a missing LAN or WAN compliant device is disclosed. The method and apparatus provide a front card configured to accept a Fast Ethernet device on a PCI-compliant bus, and the front card includes a switch which is serially disposed on a PCI_Idsel line corresponding to a particular channel of the front card. The switch is further configured to receive a sensing signal corresponding to the channel from the device. The apparatus is configured to provide the PCI_Idsel line to the front card if the sensing signal is in a first state, and to provide a low potential to the front card if the sensing signal is in a second state.
