[asterisk-ss7] dahdi, libss7 and asterisk

[Vishnu Kumar D R]

Hi,

I am configuring the ss7 with dahdi 2.6.0 and asterisk 1.8.11 (libss7-1.0.2)
I am using a Digium TE220 for this.
But i am getting error like:
[Apr 26 14:34:19] ERROR[23230]: chan_dahdi.c:12341 mkintf: Unable to find
linkset -1
[Apr 26 14:34:19] ERROR[23230]: chan_dahdi.c:16779 build_channels: Unable
to register channel '280-294'

Heres my config.

/etc/dahdi/system.conf
# Span 10: TE2/1/2 "T2XXP (PCI) Card 1 Span 2" (MASTER) HDB3/CCS/CRC4 BLUE
RED
span=10,10,0,ccs,hdb3,crc4
# termtype: te
bchan=280-294,296-310
dchan=295
echocanceller=mg2,280-294,296-310
# Global data
loadzone        = us
defaultzone     = us

/etc/asterisk/chan_dahdi.conf
ss7type = itu
ss7_called_nai=national
ss7_calling_nai=national
;ss7_internationalprefix = 00
;ss7_nationalprefix = 0
;ss7_subscriberprefix =

ss7_explictacm=yes
linkset = 1
pointcode = 2222
adjpointcode = 4440
defaultdpc = 4440
cicbeginswith = 1
channel = 280-294
channel = 296-310
networkindicator=national
sigchan = 295

/etc/asterisk/dahdi-channels.conf
; Span 10: TE2/1/2 "T2XXP (PCI) Card 1 Span 2" (MASTER) HDB3/CCS/CRC4 BLUE
RED
group=0,20
context=default
signalling = ss7
channel = 280-294
channel = 296-310
context = default
group = 63

What could be my issue?
Note: I have another 8-port Digium TE820 card which is used as PRI in the
same machine.
