[asterisk-ss7] Asterisk with one signalling link but 2 opc

[Kaloyan Kovachev]

Hi,
Asterisk (with libss7) is a signaling end-point, so you can't have two 
point-codes - you need an STP (which Asterisk is not) between the two 
boxes in order to separate the two signaling channels.
However you do not need two point-codes for this setup, but simply to 
define two groups of channels ... from the example in my previous email, 
change the linkset definitions to:

linkset=1
networkindicator=national
group=1
context=From_Span1
pointcode=1
defaultdpc=2
adjpointcode=2
cicbeginswith=1
channel => 1-15
group=2
context=From_Span2
cicbeginswith=17
channel => 17-31
sigchan=16

#include ss7.timers

linkset=2
networkindicator=national
group=3
context=From_Span3
pointcode=2
defaultdpc=1
adjpointcode=1
cicbeginswith=1
channel => 32-46
group=4
context=From_Span4
cicbeginswith=17
channel => 48-62
sigchan=47

#include ss7.timers


Now you have 4 groups on the same 2 linksets, which is equal of having 
two separate linksets on the same signalling link.
