<DIV><FONT size=2 face=Arial>Hi</FONT></DIV>
<DIV><FONT size=2 face=Arial></FONT> </DIV>
<DIV><FONT size=2 face=Arial>I don't think your suggestion of moving to libss7
is practical. I'm specifically using chan_ss7 rather than libss7 because the
carrier we're interconnecting to runs two STPs in a "mated pair" configuration
and, to the best of my knowlege, libss7 does not support that.</FONT></DIV>
<DIV><FONT size=2 face=Arial></FONT> </DIV>
<DIV><FONT size=2 face=Arial>The chan_ss7 config looks as
follows:</FONT></DIV>
<DIV><FONT size=2 face=Arial></FONT> </DIV>
<DIV><FONT size=2 face=Arial>[linkset-ls1]<BR>...</FONT></DIV>
<DIV><FONT size=2 face=Arial>combined => mated-pair</FONT></DIV>
<DIV><FONT size=2 face=Arial></FONT> </DIV>
<DIV><FONT size=2 face=Arial>[linkset-ls2]<BR>...</FONT></DIV>
<DIV><FONT size=2 face=Arial>combined => mated-pair</FONT></DIV>
<DIV><FONT size=2 face=Arial></FONT> </DIV>
<DIV><FONT size=2 face=Arial>[link-l1]<BR>linkset => ls1</FONT></DIV>
<DIV><FONT size=2 face=Arial>stp => 123</FONT></DIV>
<DIV><FONT size=2 face=Arial>...</FONT></DIV>
<DIV><FONT size=2 face=Arial></FONT> </DIV>
<DIV><FONT size=2 face=Arial>[link-l2]<BR>linkset => ls1</FONT></DIV>
<DIV><FONT size=2 face=Arial>stp => 123</FONT></DIV>
<DIV><FONT size=2 face=Arial>...</FONT></DIV>
<DIV><FONT size=2 face=Arial></FONT> </DIV>
<DIV><FONT size=2 face=Arial>[link-l3]</FONT></DIV>
<DIV><FONT size=2 face=Arial>linkset => ls2</FONT></DIV>
<DIV><FONT size=2 face=Arial>stp => 456</FONT></DIV>
<DIV><FONT size=2 face=Arial>...</FONT></DIV>
<DIV><FONT size=2 face=Arial></FONT> </DIV>
<DIV><FONT size=2 face=Arial>[host-abc]</FONT></DIV>
<DIV><FONT size=2 face=Arial>default_linkset => ls1</FONT></DIV>
<DIV><FONT size=2 face=Arial>opc => 776</FONT></DIV>
<DIV><FONT size=2 face=Arial>dpc => ls1:1001</FONT></DIV>
<DIV><FONT size=2 face=Arial>dpc => ls2:2002</FONT></DIV>
<DIV><FONT size=2>...<BR><FONT face=Arial></FONT></FONT></DIV>
<DIV><FONT size=2 face=Arial></FONT><FONT size=2 face=Arial></FONT><FONT size=2
face=Arial></FONT> </DIV>
<DIV><FONT size=2 face=Arial></FONT> </DIV>
<DIV><FONT size=2 face=Arial>The key thing about this config is that we need to
be able to receive signalling on any of the links from either stp (123 or
456) and to be able to send signalling to either stp via any of the links. To
complicate matters, the adjacent point codes are different to the STP point
codes.</FONT></DIV>
<DIV><FONT size=2 face=Arial></FONT> </DIV>
<DIV><FONT size=2 face=Arial>This is a rather complex setup, however, it's not
at our discretion to change it; that's how the other telco works. Chan_ss7 1.3
handles this fairly well. The only problem is that is cannot handle the same CIC
numbers being used on different links within different linksets that are in a
mated pair (it seemed to get confused when group reset messages came through),
however, the remote telco was willing to use different CIC numbers to work
around that.</FONT></DIV>
<DIV><FONT size=2 face=Arial></FONT> </DIV>
<DIV><FONT size=2 face=Arial>I've looked at the libss7 documentation extensively
and I cannot find anything to suggest that it can handle the mated pair as
above.</FONT></DIV>
