Abstract
A system and method for sensing and provisioning two or four wire mode for a communications link are provided. In one example, the method includes attempting to train a base wire pair associated with a base port for two-wire mode. If the two-wire mode training is unsuccessful, an unassigned port associated with a first wire pair is identified and the base and unassigned ports are configured for four-wire mode. An attempt is made to train the base and first wire pairs for four-wire mode. If the four-wire mode training is successful, a four-wire service is established using the base and first wire pairs.
