pAsepmSumOfSamASE

pmSumOfSampAseDl/UL:Total ASE DL/UL(sum of all sample values recorded) This counter is the sum of all sample values during the ROP (15 min) of total DL ASE in use in the cell. There is an internal level (gauge) counter that monitors current level of ASE in the cell. That counter is read with a regular interval (more often than 15 min) and each time it is read the value is added to this counter and the counter pmNoOfSampAseDL/UL is increased by one, sampled every 30

seconds.

pmSumOfSampAseDl/UL: Number of samples of Air interface Speech Equivalents (ASE) DL/UL . Condition: increased at every occasion when the corresponding Sum counter is increased, sampled every 30 seconds.
