Abstract
A method for maintaining reliable communication on a bidirectional communication link is provided. A receiver on the bidirectional communication link detects an error and maintains a count of detected errors. The transmitter on the bidirectional communication link polls the receiver in order to determine the count of detected errors, and performs a downshift evaluation for the bidirectional communication link. In response to performing the downshift evaluation for the bidirectional communication link, the transmitter maintains a transmission speed of the bidirectional communication link if the downshift evaluation determines that forgoing transmission speed downshift is required for the bidirectional communication link, and reduces the transmission speed of the path if the downshift evaluation determines that transmission speed downshift is required for the bidirectional communication link.
