Narrative:

While on final approach the landing gear did not extend when lowered. The gear handle was cycled once without success. The wheel page of the ECAM indicated that the gear were not down and locked in support of the landing gear lights. A missed approach was executed. The gear was lowered using the alternate gear extension and all ECAM procedures were followed. We asked for the emergency equipment and flew a successful approach to runway xx. Flight attendants were notified and a cabin advisory was issued. Time did not permit contact with dispatch. After landing we were towed to the gate due to the nature of the problem and the lack of steering. There was a minor amount of confusion with the hand signals being used by the fire department. To be more specific I was not sure whether they were notifying me that the wheels had been chocked or the pins had been installed in the gear. The tow-in was uneventful. After landing I called dispatch in order to get him in the loop and to advise him that I was unable to notify him due to time constraints.
