According to asterisk-cvs, on October 30, 2003, dacs support was added:
"Add DACS functionality to zaptel for cross connecting channels"

zaptel.conf.sample is appropriately documented:
"dacs" 	The zaptel driver cross connects the channels starting at
	the channel number listed at the end, after a colon

If I wanted to cross connect the first span to the second:
dacs = 1-24:25

If I want to cross connect just channel 3 to channel 27:
dacs = 3:27

I imagine (though haven't tried it), you can use:
dacs = 1,3-5:25
to take channels 1,3,4,5 and put them on 25,26,27,28

One note: you can only use dacs on T1/E1 spans, not the pci fxs/fxo cards.


Hope that helps...

Steve
