Hi,
  I am facing problem in configuring D-channel for TE120P card.I did the
following things 
       /etc/zaptel.conf
                span=1,1,0,ccs,hdb3
                bchan=1-15,17-31
                dchan=16
                                                                                
       /etc/asterisk/zaptel.conf
                group=1
                signalling=pri_cpe
                switchtype=euroisdn
                context=incoming
                channel=1-15,17-31
       
        then running the command "ztcfg -vv"  I get the following
output
