(a) Telehealth services may be delivered in a variety of ways, including, but not limited to:      
        (1) the store-and-forward model/electronic transmission which is an asynchronous electronic transmission of stored clinical data from one location to another;       
        (2) the clinician interactive model which is a synchronous, real-time interaction between the provider and client that may occur via telecommunication links; and       
        (3) the self-monitoring/testing model which occurs when the client receiving the services provides data to the provider without a facilitator present at the site of the client.       
      (b) A provider shall not provide services by correspondence only, e.g., mail, email, or facsimile, although these may be used as adjuncts to telehealth.
