17、A-633.38 1. Introduction. This portion of the conformance standard specifies tests to determine conformance of a Nodes Power Line or RF Symbol Encoding Sublayer to IS-60. Part One of this standard provides an overview of the conformance philosophy. The reader is urged to review that material before
18、attempting to use the details provided in this part. Three subsections under the following Test Specification heading provide Test Cases, Test Steps, and Test Case Dynamic Behavior, respectively. Test Cases are a terse description of each test to be run on a Unit Under Test (UUT). Test Steps are the
19、 building blocks for Test Cases. Test Case Dynamic Behavior is the formal expansion of each Test Case, written in the form of a series of Test Steps with a Pass or Fail outcome. 2. Test Specification. 2.1. Test Cases. This section provides the test cases for the Power Line/RF Symbol Encoding Sublaye
20、r test suite. Test cases are presented in a table format. The first column provides the purpose of the test case. The next two columns provide the test case identifier and reference (section number in Node Power Line/RF Symbol Encoding Sublayer of IS-60) respectively. The last column gives the page
21、number of the test case dynamic behavior (test case expansion). Tests that derive from mandatory protocol requirements are marked with “ “ in the Description column and are to be performed on all UUTs.

This section provides the test steps for the Power Line Symbol Encoding Sublayer test suite. TRANSMIT_FRAME - Use the te
28、ster to transmit a frame to the UUT. TRANSMIT_FRAME(ABORT10) - Use the tester to transmit a frame to the UUT, but abort transmission during the packet. Wait 10 USTs before transmitting the next frame. UUT_RECEIVE - Verify that the UUT received the transmitted frame before the timer expired. TIMER_EX
29、PIRED - The timer started after the tester transmits a frame to the UUT has expired without indication of frame reception. UUT_TRANSMIT - Force the UUT to transmit a packet to test a transmit characteristic. CAPTURE_FRAME - Capture the frame (symbols) directly on the medium, since UUT hardware gener
30、ally limits access to the CRC. COMPUTE_CRC - Compute the CRC from the frame symbols captured on the medium. Compare the computed value to the CRC that was also captured on the medium. 2.3. Test Case Dynamic Behavior. The actions of each test case are expanded in this section. A reference and identif
31、ier provide a cross reference to the test suite overview. The behavior description specifies the tests steps taken to carry out the test case. The column label “V“ is the verdict available at each step of the case. “P“ is a pass verdict, and “F“ is fail. Test Case Dynamic Behavior Reference: 6.5 Ide
