Hello Pix,

I need your help regarding one of the MFS counter P52c.

“The counter measures the cumulated time duration of all active DL TBFs established in EGPRS mode and in RLC acknowledged mode in the cell over the granularity period.”

Since its the counter , how could it gives the time

Besides the definition the unit is given like (i.e. ROUND(10x)/10).”

What (round(10x)/10)
suppose to means

I need an urgent Help ,Please

hi irfan,

Some counters are configured to count a duration, rather than a number of events. Basically, it is incrementing by the number of active TBF, each second.
For example : during 5s, the number of simultaneous DL TBF is:
5 TBF,4 TBF,5 TBF,6 TBF, 3 TBF

Over this 5seconds, the counter will print : 5+4+5+6+3 = 23 seconds.

This is an example with a counter sampling granularity of 1 second. But it could be less than 1 second, or more. But it doesn’t change anything.

ROUND(10x)/10 –> it means the counter is actually displayed with a decimal when you retrieve it from the OSS. I don’t know why they put that in the counter definition, it’s an information which is useless to the user, as far as i remember.

If there is a decimal, it means the sampling granularity is probably less than one second.

Hello Pix ,

Does the same goes with C750 Counter
which says

” Time (in seconds) during which the A channel is busy ”

???

Yes, of course, it’s exactly the same.

Usually, traffic occupacy of most of A channels are close to 3600s / hour 😉
