UCME-OPC™ allows two-way phone communication between recipients (such as technicians, field engineers or managers) and the control system. Recipients can receive voice alarm notifications yet can also change set-points, acknowledge alarms, listen to real-time values, execute programs, and a range of other actions – directly from their cell phone or landline.

UCME-OPC™ uses the Dialogic telephony board (D4PCIUxxx). Up to four phone lines can be sued to generate concurrent phone calls. If the line is busy or no answer, UCME-OPC™ will redial or switch to the next recipient on the list.
