The term linkset is missused in libss7. A libss7 linkset is a set of links that will be used for all ISUP channels on that same linkset. That would be a routeset in proper. adjpointcode needs to be defined before instantiating a signalling link, since it's a property of the sig.link. adjpointcode is only used to exchange SLTM/SLTA to verify link identity. dpc is used for ISUP messages. adjpointcode is used for MTP3 management messages.
