Yair Darshan, November 2008 Page 1www.microsemi.comComment #76 Comment #76 We are doing the same mistake we did in the past in which the 350uH adhoc was formed to resolve by allowing the droop method (implementation independent) as alternative to the OCL (specificimplementation). In order to achieve 350uH (or its equivalent droop numbers) operation when Type 2 100BT ALT A Midspan is connected we forced implementation (regulating Iunb to Type 1 levels) instead of specifying the Midspan output TX signal requirements so legacy receivers in the Switch will work. SuggestedRemedy Set the Midspan ad hoc to discuss it and propose a solution. See attached file "Midspan 100BT ALT A TX output signal template" with possible alternative.Midspan 100BT ALT A TX output signal template, Draft D3.2 COMMENT #76. Yair Darshan, November 2008 Page 2www.microsemi.comObjectives To find implementation independent method for Type 2 100BT Midspan ALT A Midspan to output TX 350uH signal performance when it is fed by 120uH signal transmitter. It will be an alternative for requiring Type 2 100BT Midspan ALT A Midspan to regulate Iunb to Type 1 levelsMidspan 100BT ALT A TX output signal ...
