Thanks for the ID, I've added it to the SVN repo. Maybe you want to do a "svn 
revert trunk/i4b/src/sys/i4b/layer1/ihfc2/i4b_hfc4s8s.h" then "svn update".

This entry should be under "double_clock" = 0.

First you must ensure that you have set the correct protocol 
using "isdnconfig". For example:

isdnconfig -u 8 -p DRVR_DSS1_TE

Then according to "man isdnconfig" it is also required to set "pcm_master" 
mode before the card will operate. That is printed out in the "dmesg". This 
is to avoid problems when you connect your HFC-4S to another clock source.

From "man isdnconfig":

           isdnconfig -m 0 pcm_64 \
                      -m 1 pcm_64 \
                      -u 8 pcm_64 pcm_map 0 1 end pcm_master te_mode \
                                    -p DRVR_DSS1_TE \
                      -u 9 pcm_64 pcm_map 0 1 end pcm_master nt_mode \
                           power_on -p DRVR_DSS1_NT

You need to use "chan_capi" from the SVN repo, and not "zaptel", to get the 
ISDN cards detected under Asterisk. Also I4B has a new Fast Fourier Transform 
Based Acoustic Echo Canceller. Did you try that?

Look at the "chan_capi/extensions.conf" and "chan_capi/capi.conf" example 
files.
