No, not really. The parameters that you are playing with in zapata.conf
are oriented around communications with the channel bank, while the fxo
parameters within the channel bank are those sensitive to the exact pstn 
line characteristics.

So, I'd have to guess that loopstart vs kewlstart has something to do with
how the 24 channels are configured on the Adit 600.
