What does "adjunct routing link #" do exactly in a vector?

[HBcity]

I read a few threads here however, I still don't fully understand what the line "adjunct routing link #" do in a vector.

Especially if it's like this in a vector,

02 adjunct routing link 1
03 adjunct routing link 2

They are used to communicate with cti / asai links to an adjuct that does screen pops or provides status of agents or identifies
ani digits for callers, etc.

A great teacher, does not provide answers, but methods to teach others "How and where to find the answers"

to find out what the links are, do I use the "List Cti link"?

Is there any AES involvement?
