Hi,
Could anybody explain the reason behind choosing 15 min and 24 hours as PM counter parameters. Why not 12 minutes or 12 hrs?
Need to understand theory and concept behind it.
e.g suppose it is excepted bit error is occurring at 10^-9 ,
how long time we have to wait to see the errors ? consider
that we are testing 2Mb/s , now 10000000/2048000= 488 seconds
= approx. 8 mins , and you can imagine that different link
capacity with different BER threshold .
Hello Ahmed,
You ask:
e.g suppose it is excepted bit error is occurring at 10^-9 ,
how long time we have to wait to see the errors ? consider
that we are testing 2Mb/s , now 10000000/2048000= 488 seconds
= approx. 8 mins , and you can imagine that different link
capacity with different BER threshold .
Please read ITU-T recommendation section 6.2.3.1.1.
Best regards, Huub.

I am trying to explain why 15 mins 24hrs chosen as PM counter,
I think this is an optimum time to see the errors as I wrote above,
right?
