ATA-186 600 Ohm Impedance Vs ATA-185 Complex Impedance??

what is the difference between these two product items ?

Product Code ATA186-I1- 600 Ohm Impedance

Product Code ATA186-I2- Complex Impedance

I am thinking of using one of these devices instead of a VG248 to connect analogue faxes,phones.

Any help would be appreciated.

*Some countries have telephone networks that list multiple impedance requirements. It is important to closely approximate the impedance of the typical handsets used in the region when selecting the proper configuration. The incorrect choice may lead to poor echo cancellation performance.

Which country are you looking for?

Is the same ATA-186 model used in the US, Canada, Mexico and Guatemala?

Oops. Didn't see that Tom had replied earlier. Listen to him! I started learning AVVID from his internal web site :^)

I AM LOOKING TO USE ATA-186 in the UK-England.

...it seems like the 600 ohm impedance model (ATA-186-l1) is the one for me..from one of the other replies....

I would appreciate the url from CCO, this was obtained from...so I can investigate this further before I design/purchase for a customer.
