, � II <br /> . + <br /> r. . } <br /> City of Decatur Mobile Data System Acceptance Test Plan ' <br /> Inbound Traffic Test <br /> The inbound traffic test will be conducted by performing the following steps in the <br /> following sequence: <br /> • The test host will be connected to the RF system's BDLC. <br /> � • The test vehicles that are equipped with the 96+MRMs and mobile test <br /> workstations will be located near the transmitter site. - - - - <br /> • A series of test procedures will be executed to verify that the test host,the <br /> BDLC,and the 96+MRM-equipped test vehicles are communicating. <br /> • The test host will open a log file which will be associated with the tower <br /> site. <br /> • The mobile test workstation in each of the 10 vehicles will generate and <br /> pass to the 96+MRMs a series of test messages directed to the test host. <br /> • Each message will consist of 43 characters of user data and will be passed <br /> to the 96+MRMs at a steady rate.At the end of one hour,each of the <br /> mobile test workstations will have passed the messages per hour per <br /> vehicle of inbound traffic,as defined in the Projected Workload,to its 96+ <br /> MRM. <br /> • The test host will record the messages received,as well as the <br /> ACKs/NAKs generated by the BDLC in the tower log file. <br /> • The generation of test messages at the rate described above will continue <br /> for one hour.At the end of one hour,the mobile test workstations will <br /> stop generating test messages and the tower log file on the test host will <br /> be closed. <br /> • The test host will generate a report that will list all test messages that <br /> were successfully received from the mobile test workstations as evidenced <br /> by an ACK message. <br /> • If the total inbound messages per hour per vehicle as determined above <br /> meets or exceeds the total inbound messages per lwur per vehicle shown <br /> in the input model used in the Da'rAxAD�o Projected Workload <br /> attachment previously referenced,the inbound component of the <br /> throughput test will be determined to be successfully completed. <br /> � SUCCESSFUL TEST COMPLETION <br /> Although discussed separately,both the outbound and inbound components of the throughput <br /> test will be conducted simultaneously and successful completion of the overall throughput test <br /> is conditioned upon components handling the required workload. <br /> �iV Il/�R/�V�O" <br /> 14 <br />
