asterisk users - Apr 2010 - How Cisco ATA 186 through SCCP with skinny.conf ?!

Hi people,
I have a Cisco ATA 186 which understands only the SCCP protocoll,
therefore I am a pure beginner and I hope that anybody of you could help
me.

How will I configure the ATA which has 2 analog ports?

For any support I would kindly thank you
