Assuming you are flying a 757 or similar with a 400kt single engine out speed, you would not be ETOPS and therefore require an adequate airfield. There are however "grandfather rights" on certain routes.
An Adequate airfield is one which at the anticipated time of use will be available and equipped with services which include ATC, sufficient lighting communications WX reporting, Noav Aids and Safety cover.
A suitable airfield is an adequate airfield with weatherreports or forcast that are likely to be above the normal AOM at the time of intended operation.
