Abstract
Techniques for supporting optical and electrical protocols, such as on the ports of a line card in a network device, are provided. A port on a line card supports optical and electrical connections. The PHY monitors a signal to determine if the transmission connection at the port has changed, such as from optical to electrical, or vice versa. If there has been a change, the PHY is directed to reset a port to correspond to the appropriate transmission connection. By resetting the port, the PHY changes the protocol that is utilized with the signals (e.g., NRZI or 3-Level MLT3).
