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).

I’m getting a strange error when I start up asterisk and I can’t tell if it’s a problem with the ss7 linkset or something hardware related.
 
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
