SS7 Problem

Hi,
I am trying to configure libss7-2.0.0 on asterisk-13. I have 6 E1 and i am trying to configure 1st E1.
Please see the system.conf file:
span=1,1,0,ccs,hdb3

termtype: te

bchan=1-31
#dchan=16
#mtp2=16
echocanceller=mg2,1-31

Please see the chan_dahdi.conf file:
linkset =1
pointcode =XXXX
adjpointcode =XXXX
defaultdpc =XXXX
networkindicator=national_spare
group= 1
language=en
context=from-ss7
switchtype=euroisdn
pridialplan=unknown
prilocaldialplan=national
signalling=ss7
toneduration=100
callerid=asreceived
usecallerid=yes
callwaiting=no
usecallingpres=no
callwaitingcallerid=yes
threewaycalling=no
transfer=yes
canpark=yes

callreturn=yes
echocancel=yes
echocancelwhenbridged=yes
echotraining=yes
callgroup=1
pickupgroup=1
cicbeginswith =1
channel = 1-31
sigchan = 16

When i use asterisk cli, it show me the below error:
localhost*CLI> ss7 show channels
No such command ‘ss7 show channels’ (type ‘core show help ss7 show’ for other possible commands)

if i disable sigchan=16, it shows me- no ss7 running.

Please tell me how can i configure for1st E1 link up?
