Abstract:
1. A physical layer device for communication with a link layer device in a network-based communication system, the physical layer device comprising: payload extraction circuitry which extracts a payload from an ingress synchronous transport signal received over an ingress link; and payload insertion circuitry which inserts a payload received from the link layer device into an egress synchronous transport signal for transmission over an egress link; wherein the payload extracted from the ingress synchronous transport signal is converted from parallel to serial form in the payload extraction circuitry and transmitted by the physical layer device to the link layer device in serial form in over an output serial data line of a serial interface; and wherein the payload inserted into the egress synchronous transport signal is received by the physical layer device from the link layer device in serial form over an input serial data line of the serial interface and converted from serial to parallel form in the payload insertion circuitry.
