Minimal PM3 configuration for call answering

Hi everybody:
I'm an ISP/portmaster newbie that has a PM3 plugged into 2
channelized T-1 lines that are being turned up by Pac Bell. Right
now, calls to the CT-1 phone # get a busy signal. (This busy signal
has a shorter delay between tones than a "normal" busy signal.) What
I'd really like to know is, what is the minimal set of configuration
commands that need to be entered in order to get the digital modems to
answer the incoming call?
So far, I have set the two T-1 ports to "inband", with Pac
Bell's specs ( ESF, B8ZS, wink start ). I've also put a DM-10 card
into the PM3. The PM3 LEDs show that there is physical synchronizatin
with the switch, but D channel signaling is not up (since we have
inband signalling). Included below are the outputs from some show
commands. As you can see, many things remain to be configured, but at
this moment, I'm only interested in the ones that are directly
relevant to the busy signal that I'm getting. Please let me knw if I
should provide any more information. Thanks very much for any help
that you can give. Pac Bell is waiting for this to be resolved, and
it's quite an unpleasant role reversal for Pac Bell to be waiting on
me :).
