adnChassisClockPropagationStatus
Module: ADN-MIB
OID (symbolic): ADN-MIB::adnChassisClockPropagationStatus
OID (numeric): 1.3.6.1.4.1.637.3.1.5.15.1.1.10
Node type: OBJECT-TYPE
Type: INTEGER
Access: read-only
Description: This object provides the status of the clock propagated from this chassis to the next. It is a bit map and a set bit indicates that the clock is present.
1 - primary 8 kHz MSC (Medium Speed Coupler) 2 - backup 8 kHz MSC 4 - primary line timing (LT0) 8 - backup line timing (LT1) 16 - primary SDH (Synchronous Digital Hierarchy) 32 - backup SDH 64 - primary PDH (Plesiochronous Digital Hierarchy) 128 - backup PDH A value of 0 indicates that no clocks are being propagated. Note that the value of this object is 0 for a single-chassis system.
What is adnChassisClockPropagationStatus?
This OID is a bitmap showing which timing signals are being propagated from this chassis downstream to the next chassis in the chain. Engineers monitor this to ensure timing distribution is complete—if a clock signal fails to propagate, downstream equipment will lose sync. For example, a value of 21 indicates that the primary 8 kHz MSC (bit 0, value 1) and primary SDH (bit 4, value 16) are propagating correctly, but others may be missing.
