SS7 2 T1s >>> 2 linksets same point code

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



My carrier is telling me the following.  Does this make sense to any one:

 

My log is giving me a SIO (service information octet) please ensure that
your service indicator is set to MTP-2

Can anyone make sense of T4 expired in the logs below:

 

Link state change: ALIGNED -> PROVING

We were able to get the linkset up but its moving up and down.  See the logs
below.  Any suggestion as to why this might be happening.  Could it be due
to the clock?

Link state change: IDLE -> NOTALIGNED

I am hoping someone can offer some advice as to why the second dchan  is not
aligning.  See details below.  Carrier is using Nortel on his end and we
checked everything.  

Two T1s.     1 linkset.  Signaling on channel 1 and 25. TE410.  We can pass
cals on both T1s but only 1 D channel is aligning.

The linkset is up but it seems as if the second D channel on slot 25 is not
aligning.  I am using 1 linkset and I am able to pass calls on both T1s.

 

I am getting the following error:

 

aislecomss72*CLI> ss7 debug linkset 1

Enabled debugging on linkset 1

 

Link state change: NOTALIGNED -> IDLE

Link state change: IDLE -> NOTALIGNED

 

aislecomss72*CLI> ss7 show linkset 1

SS7 linkset 1 status: Up

 

Is there a more detailed debug level that can tell me exactly why I am
getting this msg.

Hi,

I am using two T1 for SS7 on the same box.  Both T1s are using the same
point codes.  I have each T1 setup as its own linkset (Linkset 1 and linkset
2).

The second linkset is not coming up.

Is there any thing wrong with my config or setup?  Can I have both T1s usins
the same point code.  I did it this way so that if 1 T1 goes down the second
linkset and T1 stays up.
