[asterisk-ss7] SS7 2 T1s >>> 2 linksets same point code

[Dave George]

Found a typo in cicbeginswith that solve the CIC numbering.  

We are now passing calls on both T1s.  However the d channels on the second
t1 is not aligning.  See our config below.  The carrier is getting an alarm
on his d channel on the second T1.  Carrier is using Nortel DMS.


Link state change: NOTALIGNED -> IDLE
Link state change: IDLE -> NOTALIGNED

T4XXP (PCI) Card 0 Span 1                OK      0      0      0      ESF
B8ZS YEL      0 db (CSU)/0-133 feet (DSX-1)
T4XXP (PCI) Card 0 Span 2                OK      0      0      0      ESF
B8ZS YEL      0 db (CSU)/0-133 feet (DSX-1)

Chan_dahdi.conf
cicbeginswith = 102
sigchan = 1
channel = 2-24
sigchan = 25
cicbeginswith = 126
channel = 26-48



system.conf

span=1,1,0,esf,b8zs
span=2,1,0,esf,b8zs


bchan=2-24
mtp2=1

bchan=26-48
mtp2=25

I decided to use 1 signaling link.  My new problem is that the CIC on the
second T1 does not line up.  It is starting at 125 instead of 126.

This is what the carrier want.
T1 1:  Slot 1 D channel CIC 102 to 124
T2 2: Slot 25 D Channel  CIC 126 to 148

cicbeginswith = 102
channel = 2-24
cicbeginwith = 126
channel = 26-48
sigchan = 1
sigchan = 25


asterisk is counting 125 as a CIC.  See results from: ss7 unblock linkset 1

Sending remote unblock request on CIC 122
Sending remote unblock request on CIC 123
Sending remote unblock request on CIC 124
Sending remote unblock request on CIC 125
Sending remote unblock request on CIC 126
Sending remote unblock request on CIC 127

You'll want to set up the same linkset, and use slc=0 and slc=1, the SLC 
has to match what the remote end is using. This is of course assuming 
you're connected using F links since the adjpointcode and defaultdpc are 
the same as each other.

usins the same point code.  I did it this way so that if 1 T1 goes down the
second linkset and T1 stays up.
