After some testing, I am confused about how libss7 works in an ANSI A-link setup (all dummy point codes) setup Switch A pointcode = 001-001-001 adjpointcode = 248-001-001 (STP ) adjpointcode = 248-001-002 (STP ) defaultdpc = 001-001-002 Switch B pointcode = 001-001-002 adjpointcode (not defined) defaultdpc = 001-001-001 My question is on linkset alignment, should the linkset use the adjpointcode to align the links. It appears that it is using the defaultdpc. (That would be F-Link setup). My linkset comes up and is aligned, and calls pass, which if a true A-Link setup, should not happen...... I am confused that my links are aligning, and the 248 point codes do not exist. If it is a true A-link then the alignment should be to the adjointcodes ?? What am I missing or what is happening......
