It looks like you have a very low level problem on that line. We are
sending the other end SIO (To start the alignment, but the other end is
not going through the alignment process. The only thing I can think of
is that either:
A) You don't have your signalling channel setup correctly. Are you
using a sangoma card? I've seen weirdness like this with sangoma
cards. The problem was a misconfiguration with the dchannel wanpipe
setup. Another possibility is that maybe it's a 56kbps link and you're
trying to use it in 64kbps mode.
B) The line is not configured at the other end to begin alignment.
I'm suspecting it is probably something along the lines of option A.

I changed this piece of code in ss7linktest.c before trying this:

Here is the output:

As far as ansi point codes go, what is the appropriate method for
converting the dotted format codes to a format usable by asterisk?

Try using the ss7linktest program that is included with libss7. The
syntax is "ss7linktest x" where x is the zap channel that your
signalling is on. Paste the output of that to your next reply.

The link won't actually come up at all. This message scrolls through
asterisk so fast that it's impossible to do anything in the CLI when I
start it. The odd part is that now that I downloaded the latest 1.4
beta 2 zaptel and installed that and rebooted the box it seems that
the messages have stopped but now asterisk is doing nothing at all
with the SS7. No messages appear in the logs relating to it and my
CopperCom sits in an activating state on the f-link. The config is
the same as before, any ideas?

Unless you're seeing link related problems (link doesn't come up and
those are scrolling continuously) you shouldn't worry about those
messages. MTP2 is designed to work around link layer hickups such as
this. You may see better performance though if you set your dchan to
hardhdlc instead (though that only works on the TE4xxp and TE2xxp).

This is what asterisk outputs:
[Oct 18 12:02:16] ERROR[7160]: chan_zap.c:8273 ss7_linkset: HDLC
Abort!
This is the SS7 part of my Zapata.conf:
signalling = ss7
ss7type = ansi
linkset = 1
pointcode = 351400
adjpointcode = 351240
defaultdpc = 351240
networkindicator=national
cicbeginswith = 1001
sigchan = 1
channel = 2-24
This is from my zaptel.conf:
span=1,1,0,esf,b8zs
bchan=2-24
dchan=1
defaultzone=us
