Joseph,
I am using Different Signalling Channel(1)and Voice
Channels(2-24). Nortel side is the Clocking source for the T1 circuit.
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.
Is there any logging or command that I can run to see the normal
flow of communication being established with Nortel ( Maybe wireshark ).
Please suggest.
Regards,
Girish
