Ohio Revised Code Title I. State Government § 128.241

(A) In the case of a multiline telephone system that is capable of initiating a 9-1-1 call, the system is connected to the public switched telephone network in such a way that when an individual using the system dials 9-1-1, the call connects to the public safety answering point without requiring the user to dial any additional digit or code.

(B) The system is configured to provide notification of any 9-1-1 call made through the system to a centralized location on the same site as the system.  The business service user is not required to have a person available at the location to receive a notification.
