Hi
I receive from a phone provide 4 E1 ISUP ss7 connection setings, and in the configuration i only have 2 CIC signals to configure, I need to know on the configuration if i can skip the configuration an dchan I mean if is possibile to do this :
from
/etc/dahdi/system.conf
#span=1,1,0,ccs,hdb3,crc4
span=1,1,0,ccs,hdb3
termtype: te
bchan=1-15,17-31
dchan=16
echocanceller=mg2,1-15,17-31
to
/etc/dahdi/system.conf
#span=1,1,0,ccs,hdb3,crc4
span=1,1,0,ccs,hdb3
termtype: te
bchan=1-31
#dchan=16
echocanceller=mg2,1-31
I need this because i want to map all the 122 VOICE CIC and I only have digium card with 4 span the model of the card it is 1TE435BF.
Thank you in advance,

You cannot have SS7 without a D channel to carry it. I don’t know if Asterisk allows sharing a D channel across multiple E1’s, but you will still need at least one D channel. That is fundamental to SS7. Common channel signalling has to have a common channel.
I suppose that one could have a signalling channel that wasn’t over the E1 at all, but I suspect implementations of that are rare to non-existent. In any case, both ends of the link have to make prior agreement, so you cannot deviate from channel 16 without agreement from the other end.
Hi
so the configuration will be somenthing like this where my singnalling cic are CIC 1 and cic 32 the rest are voice:
"
span=1,1,0,ccs,hdb3,crc4
dchan=1
bchan=2-31
Span 2: TE4/0/2 “T4XXP (PCI) Card 0 Span 2”
termtype: te
span=2,2,0,ccs,hdb3,crc4
dchan=32
bchan=33-62
Span 3: TE4/0/3 “T4XXP (PCI) Card 0 Span 3”
termtype: te
span=3,3,0,ccs,hdb3,crc4
#dchan=63
bchan=64-93
Span 4: TE4/0/4 “T4XXP (PCI) Card 0 Span 4”
termtype: te
span=4,4,0,ccs,hdb3,crc4
#dchan=94
bchan=94-124
"
and
"
cicbeginswith = 2
channel=2-31
cicbeginswith = 34
channel=33-62
cicbeginswith=65
channel=63-93
cicbeginswith=97
channel=94-124
sigchan = 1
sigchan = 32
"
thank you in advance

Hi
is working , the configuration that I put is working and is respecting the standard. Very nice.
Best regards
