It seems likely that your suspension was administrative, due to your failure to perform a breathalyzer. However, we have no way of investigating your record for any charges that may have been filed against you, or to determine the basis of your suspension for the new charge.
If you have kept your address up to date on your driver's license, you would normally receive a notice of an administrative suspension. If you have failed to do that, a notice may have been sent to your former address. Check with the DMV.
