A method of sending data through a network from a first computing device to a second computing device is described, where the computing devices adhere to a packet-based network protocol. The electrophotographic printing system includes a photosensitive drum, a first and second retractors and a paper presser. Each of the jaws includes a semi-cylindrical gripping surface which are adapted to move toward each other to grip a cable therebetween when the jaws move toward the opening and are able to move away from each other when the jaws move away from the opening so as to release a cable located therebetween. The low rate channels generated by the low rate physical layer circuit share a same frequency band as a corresponding high rate channel generated by the high rate physical layer circuit.
