¿µ¹®³»¿ë¿ä¾à | This standard specifies detailed test methods and considerations in each test
procedure for terminal equipment connected to CATV facility to test input and output characteristic of downstream, modulation method, output level, output impedance, return loss and spurious of upstream channel having an ATM sell structure. But the concrete test procedures and performance criteria of upstream channel with IP packet structure for data communication terminal equipment connected to CATV facility is referred to [3] in Appendix I. Also, in this standard, in order to test conditional access function of terminal equipment not adopting CableCARD, this standard presents test methods and procedures for confirmity assessment of terminal equipment which complied with [4] in Appendix I. But this standard dose not deal with the test methods for conditional access function of terminal equipment not using CableCARD. |
