A heat dissipating device having a linear heat dissipating unit and a fanless LED lamp using the device are disclosed. If an error condition is detected at a GFP port of the platform, a correspondence is retrieved between said GFP port and a VID and a deregistration message including said VID is forwarded to the service unit. The system and method also provides for an interface device which connects to a conventional fax device for communicating E-mail addresses and routing hardcopy documents to the E-mail network, and provides a means for embedding the functions of the interface device into conventional fax devices.
