The PEC CallAhead® System is an application that provides utility companies with a device capable of calling their customers in order to inform them that a service truck is on the way to the service site, prior to the time of the visit. The utility service can use the detected status of the CallAhead® System to determine whether to dispatch a service truck or not.
The CallAhead® System interfaces with the Utility Field Service Management System. (UMS) through an RS-232 Serial Communication Port. The call request made at the UMS is transferred to the PEC CallAhead® Terminal via the RS-232 port. The CallAhead® System processes the request, makes the call according to the time and format requested, plays the message, and returns the detected status back to the UMS via the RS-232 port.
