Hello,
I've search on the lists and google in general regarding setting up
hardhdlc in /etc/zaptel.conf.
Nobody sais anything about a specific configuration, except replacing
"dchan" with "hardhdlc" in /etc/zaptel.conf
Though, the link does not come up and I get tons of errors saying:

Is there something else that should be done on the code/patch side or
on the configuration? The code is up to date with svn.
Ok, I apologize about this (I wrote the hardhdlc code) but the current
implementation does not perform well enough to service an SS7 link. I
noticed similar problems as well when I started working on libss7. I
have been doing my development on libss7 with the dchan option instead.
I just finished a big performance related rewrite of the wct4xxp
driver, so maybe after I get that released I can get enough time to
look at the hardhdlc code and figure out what's going on with it on
SS7.

The card is TE205.
/etc/zaptel.conf looks like this:
span = 1,1,0,ccs,hdb3
bchan=1-15
#bchan=1-31
dchan=16
#hardhdlc=16
bchan=17-31
/etc/asterisk/zapata.conf looks like this:
[channels]
signalling = ss7
ss7type = itu
linkset = 1
context = from-dcs
language = en
rxgain=0.0
txgain=0.0
pointcode = 14381
adjpointcode = 14369
defaultdpc = 14369
switchtype = national
This is a pri only option, by the way. (switchtype) It doesn't have any
affect on SS7.
networkindicator = national
group = 1
sigchan = 16
cicbeginswith=1
channel=>1-15
cicbeginswith=17
channel=>17-31
Regards,
Alex
