TDM422 - Need to know Port Position and Signaling

[munnan]

Hi,
We have bought two TDM422 Digium Cards from http://voipon.co.uk

they have written to me in email about port positioning and signaling as follows :

Motherboard - port1 FXS - port2 FXS - port3 FXO - port4 FXO - Otherside of case

today I have found new information from
http://www.voip-info.org/tiki-index.php?page=TDM400P

there is written

“Port #1 is the one toward the top of the computer (away from the motherboard), Port #4 is the port closet to the motherboard. There is a green LED next to each port.”

Now both these information , one from the company I brought the card and this website, are different even contradicting.

Can anybody help me out in this positioning and signaling of TDM422 analog Card ??

thanks,
