Not sure what the "dock" is. If you are on the PS3 and trying to get Revolution, it should be available now. If you are in the UK it may take most of today to be released (out of Treyarch's control). Since you have the Season Pass, be sure to download it from the In-Game store and not the PS store so that the price will be free.
If you aren't talking about the Revolution DLC then please clarify what "elec" or "dock" is. Also, this doesn't really pertain to COD Elite so you may want to move it to either the PS3 or General Discussions forum.
