DGN of CLK fails.

• DGN of CLK fails.
• Check the clock hardware i.e. CCK and NSC card one by one to isolate the fault. Generally if the CLK DGN fails then this may be due to the faulty NSC as the main role of CCK is to distribute clock to BTU and SSU.
• Also some time due to the fault in CBX the DGN of clock fails but this is only a feeble chance.
• However in the DGN of CLK, the role of active clock is very high as it gives the Duplex clock and if there is disturbance in the duplex clock it reports ‘reset clock test fail’.
