The PEC Call AheadTM 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 Call AheadTM
System to determine whether to dispatch a service a truck or not.
The Call AheadTM 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 Call
AheadTM Terminal via the RS-232 port. The
Call AheadTM 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.
