Differences between ATA 186 I1 and ATA 186 I2

I'm sorry for this question because it's not so technical but sincereley I didn't find anybody able to give me an answer.

To provide a solution to a customer I have been asked for the differences that appear in the price lists between the ATA 186 600Ohm impedance and the ATA 186 "complex" impedance. Are there any country issue ? Could anybody help me since I didn't find documentation on these two hints ?

Thanks in advance

"*NOTE: Some countries have telephone networks that list multiple impedance requirements. However, it is important to closely approximate the impedance of the typical handsets in use in the region when selecting the proper configuration. "

(1) I1 configuration = 600W FXS impedance

(2) I2 configuration = 270W in series with 750W and 150nF in parallel FXS impedance

"(3) Power cable configuration, power supply unit is universal"
