This object configures two options: a) To invert the clock sent by HS1/HS2B with the TX data or not. b) If DCE,to expect the receive clock looped back from DTE or not. If DTE,to loop back the receive clock from DCE or not. nonInvertedAndNotLooped(1)- a)=dont invert, b)=dont expect rcv clock/ dont loop rcv clock invertedAndNotLooped(2) - a)=invert, b)=dont expect rcv clock/ dont loop rcv clock nonInvertedAndLooped(3) - a)=dont invert, b)=expect rcv clock/ loop rcv clock invertedAndLooped(4) - a)=invert, b)=expect rcv clock/ loop rcv clock Enums 1 and 2 are applicable for X.21/HSSI/V.35 interfaces. Enums 3 and 4 are applicable only for V.35. Default for X.21/HSSI is nonInvertedAndNotLooped(1) Default for V.35 is nonInvertedAndLooped(3) This object is not used by FRSM-HS2/FRSM-HS2B-HSSI This object is used by FRSM-HS2B-12IN1 and default values are nonInvertedAndNotLooped(1) for X.21, nonInvertedAndLooped(3) for V.35.
