x21InvertClock
Module: CISCO-WAN-AXIPOP-MIB
OID (symbolic): CISCO-WAN-AXIPOP-MIB::x21InvertClock
OID (numeric): 1.3.6.1.4.1.351.110.4.5.1.1.1.9
Node type: OBJECT-TYPE
Type: INTEGER
Access: read-write
Description: 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
What is x21InvertClock?
This read-write object configures two related clocking behaviors for the HS1/HS2B card: whether to invert the transmit clock sent with TX data, and, depending on DTE/DCE role, whether to expect or provide a looped-back receive clock. An administrator adjusts this setting to resolve clocking incompatibilities with connected equipment. For example, an engineer seeing consistent bit errors traceable to clock phase issues with a particular DTE device would try the inverted setting to see if it resolves the mismatch.
