1. We need to ensure deviation between the transmit clock rate and the receive clock rate within a proper range to ensure the correct transmission and processing of data. Beside, it may leads pointer justification which can trigger Bit Error.

Copy the code

It seems very useful to me .... i have some enquiry also

I along with customer, do a test to check when LTI alarm came. So, to do test, we first delete External clock source so that its clock switch to internal. We wait more than 10 mins but no LTI alarm came.
Guys, can you please tell me, where was the fault ?

Guys, Please like and comments on the following O&M case, would be appreciated for valuable comments, or any recommendation.

Dear Faheem, Thanks for recommend. I will definately join and ask some questions. But please dont forget to share your experience, knowledge or case regarding clock issue in this FAQ.

Is there any difference between Service switching and Clock switching ?

There might have some difference based on the application. But however, hope some experts will ans this Q.@s84029455

Is there any difference between Service switching and Clock switching ?

Ok , Eagerly waiting for the reply.

I learn below from a case, though i am not sure about this.
In the case of service switching, if the protection channel is available, the services are switched to the protection channel regardless whether the WTR time expires. In the case of clock switching, the clock is switched to the standby clock source only after the WTR time expires.
