2、or, Maurice Not for Resale, 04/29/2007 02:22:02 MDTNo reproduction or networking permitted without license from IHS -,-,- Approval of an American National Standard requires review by ANSI that the requirements for due process, consensus, and other criteria for approval have been met by the standards

Substantial agreement means much more than a simple majority, but not necessarily unanimity. Consensus requires tha

19、A set of timers, as described below, is used in the test suite, their values must be initialized prior to the beginning of test, unless a default value is specified. T_REQ: the Target Token Rotation Timer (TTRT) is configured in the IUTs MAC in units of s. This value will be converted to units of 80
20、 ns for MAC claim process. T_REQ1: an alternate TTRT configured in the IUTs MAC in units of s. This value will be converted to units of 80 ns for MAC claim process. T_REQ2: an alternate TTRT configured in the Others MAC in units of s. This value will be converted to units of 80 ns for MAC claim proc
21、ess. T_Max: the maximum token rotation time in s. D_Max: the maximum ring latency. The default value is 1773 s. T_Non_Op: time to allow ring recovery to occur before duplicate address conditions are examined. The default value is 1 s. RM_React: maximum for the RMT state ma- chine to recognize that t
22、ransition conditions exist and to execute the appropriate transition. The default value is 83 ms. T_Jam: time for which Jam Beacon is sent. The default value is 370 ms. T_DBJ: time to start the second Beacon of the Double Beacon Jam after the first Beacon is sent. The default value is 82 ms. T-Direc
23、t: time for which a Directed Beacon is sent before the Trace function is invoked. The default value is 370 ms.
