<div>Joseph,</div>
<div> I am using Different Signalling Channel(1)and Voice Channels(2-24). Nortel side is the Clocking source for the T1 circuit. </div>
<div> Also, I agree that it does work , however for me it is only locking the T1 with Nortel when I am using ss7linktest program.In the normal operation On the Nortel Side I see the T1 Link being Non-Aligned. </div>
<div> Is there any logging or command that I can run to see the normal flow of communication being established with Nortel ( Maybe wireshark ).</div>
<div> </div>
<div> Please suggest.</div>
<div> </div>
<div>Regards,</div>
