Starting with Fast Ethernet, the physical layer specifications are divided into three sublayers in order to simplify design and interoperability: • PCS (Physical Coding Sublayer) - This sublayer performs auto-negotiation and basic encoding (e.g., 8b/10b), lane separation and recombination. For Ethernet, the bit rate at the top of the PCS is the nominal bit rate, e.g. 10 Mbit/s for classic Ethernet or 1000 Mbit/s for Gigabit Ethernet.
