I don't really understand how I can do so.

zaptel.conf contains:

span=1,1,0,ccs,hdb3
dchan=1
bchan=2-31
span=2,1,0,ccs,hdb3
bchan=32-62

I tried to use "bchan=33-63"  but this activates the 3rd span on the 
digium card which is not what I intend to do.

zapata.conf contains:

signalling = ss7
ss7type = itu
linkset = 1
pointcode = 6
adjpointcode = 2
defaultdpc = 2
cicbeginswith = 1
networkindicator=national_spare
sigchan = 1
group = 1
channel = 2-31
channel = 32-62

Is there anything that I need to do in case the switch does not do the 
reset?
