Data that has been programmed locally through an operating panel may also beloaded to the remote location. The ADT Service Terminal is located at the remote location, and thetransmission takes place over the dialing network by means of a Service Channel. Downline loadingrequires the Service Terminal.Downline loading can be initiated from the Service Terminal or by the ADT installer at the customer'spremises. The sequence of events that are involved in the downline loading are determined by the typeof communication that is involved, and whether the operation is being done for the first time duringinstallation or is being done for a subsequent change to an existing customer database.Downline Loading SecurityAs a security measure, in order to prevent the downline loading of data from a source other than ADT,the control unit will not accept any data without first calling back the Service Terminal. This callbackrequirement is controlled by an activation byte. On a new installation, when the control unit is presetto the factory defaults, the activation byte is cleared in the control unit's memory. This permits thecontrol unit to accept data from the service terminal without first calling the CCC and the ServiceTerminal. When the initial data has been downloaded, the control unit communicator verifies thetelephone number of the CCC and the service terminal by making a callback to each. If the telephonenumbers are correct, the service terminal sets the activation byte in the control unit memory to preventattempts to download unauthorized data.Programming the Control Unit for Downline LoadingIn order for the control to call back the Service Terminal for a downline load, a service terminal phonenumber must be programmed into the control unit.
