Name:BER (Bit Error Ratio)
OID:1.3.6.1.4.1.119.2.3.69.401.8.1.1.13.1 - Base
OID:1.3.6.1.4.1.119.2.3.69.401.8.1.1.14.1 - E-factor

Explanation:
If Base is "0" and E-factor is "10", the real BER is: 0E-10 (the best value)
Problems in reception will appear if the BER reaches 1.0E-4
On Cacti graph the best practice is to use following:

berBase = (100 - berBase) /100
berTotal = berBase + ber-e-factor
* berTotal will be used as value on graph
* For a limit draw a line at 4 (1.0E-4)

NOTE: For cacti the recommendation is to do some math
For MER:
CDEF function is:cdef=CURRENT_DATA_SOURCE,32768,/,128,*
in other words: db = MER*128/32768

For BER:
Divide the value by 100, mark the critical limit at 20. On the same graph draw the MER (scale fits, and vertical description is "dB or BERx100").
If BER is more than 20 on the graph, itsa problem and if MER is less than 20, it's a problem too.
