A device provides layer two services between customer networks that are coupled by one or more intermediate computer networks. A rear portion of vamp is connected to a connection wall on the sole plate. A reset piston may be included in the rocker arm to selectively reset the position of the lost motion piston. A non-spread spectrum signal demodulator is communicatively coupled to the spread spectrum signal demodulator and demodulates, in response to the packet header detection signal, a non-spread spectrum modulated data payload within the data packet. In response to the shaft rotation, an alternator generates sufficient electrical power to sustain the operation of the control module without an external power source. After the modulation the digitized watermark is embedded into the digital file by distributing the modulated elements of the watermark into the selected addresses.
