Re: SS7 UPU FROM ASP

Hi Barry,

Thanks for the responce.

I understand that ASP at the AS does not have MTP3 layer (just M3UA). As so
when you say M3UA implementation-dependent primitive to the MTP3 layer, do
you mean a M3UA implementation-dependent message to the MTP3 layer at the
SG?


Thanks,
Emmanuel
