don't you use common schannel '16'? (but that's ok, over here is commonly used 16 as signalling channel).

anyway, I still get NOT_ALIGNED messages:

# ss7 link status
linkset wiltel, link l1, schannel 16, sls 0, NOT_ALIGNED, rx: 20, tx: 0/4, sentseq/lastack: 127/127, total    114448,    114544

thank you.
