[asterisk-ss7] Two Asterisk boxes, only ONE signal link

Hi,
If I can understand , this configuration is for "TE410p" installed asterisk
box [The Telco Part, Simulating as Telco equipment] . Think at the telco
scenario , if there is Motorola or Erricsion or Siemens switch , then I
think it could not be possible to use cluster service at Telco end and we
have no control of Telco part ...
[cluster]
port => 5040
l4 => AST000012#if-1
l3 => AST000015#if-1
So I think we have to manage signaling link for "Asterisk_2" over
"Asterisk_1" .
I am also trying to make a telco scenario with "TE405P" board and here is
below ss7.conf file
[linkset-Asterisk1]
enabled => yes
enable_st => no
use_connect => no
hunting_policy => even_mru
context => default
language => en
t35 => 4000,st
subservice => auto
[linkset-Asterisk2]
enabled => yes
enable_st => no
use_connect => no
hunting_policy => even_mru
context => default
language => en
t35 => 4000,st
subservice => auto
[link-l1]
linkset => Asterisk1
channels => 1-15,17-31
schannel => 16
firstcic => 1
enabled => yes
[link-l2]
linkset => Asterisk2
channels => 1-31
schannel =>
firstcic => 32
enabled => yes
[host-TELCO]
enabled => yes
default_linkset => Asterisk1
opc => 0x1
dpc => Asterisk1:0x2,Asterisk2:0x2
links => l1:1,l2:2
if-1 => 192.168.10.15
Please correct me and input some advice .
Best Regards,
..Tusar..
