 chan_ss7 is typically used like this:

 STP --------- SEP (Asterisk / chan_ss7)    One signalling link


 STP ---------
              |
             SEP (Asterisk / chan_ss7)       Two signalling links
              |
 STP ---------

As far as I undestand, A links are the links from STP to SEP in the
ascii-drawings above. So chan_ss7 uses A links for sure.

 chan_ss7 can also work in a cluster:


 STP ------- SEP (Asterisk / chan_ss7)
              |
              |
              |
 STP ------- SEP (Asterisk / chan_ss7)

 Now, the links between an STP and SEP are still A-links, but I think
 the interconnect between the two SEP's can be considered an F link.
 The interconnect is typically a crossed ethernet connection though, so
 I don't know if it can be fully qualified as an F link according to the spec.
