<DIV></DIV>Okay. I ordered a commercially made T1 crossover cable, connected all
of the cables and rebooted both computers. <BR><BR>I no longer get the 'Got
S-frame while link down' or 'HDLC Bad FCS' errors. However, I still receive the
series of 'Detected alarm on channel NN: Red Alarm' and 'Unable to disable echo
cancellation on channel NN'. Followed by the alarms clearing. <BR><BR>At this
point I am confident that the cabling is not the problem. I have included my
zaptel and zapata conf files again below. <BR><BR>Is there a way to make the
second TE120P card pass on the timing received from the first? (rather than
using software timing for the pri_net signalling) <BR><BR>The errors all seem to
be about echo cancellation... What do I need to do to force asterisk to never
disable echo cancellation?<BR><BR>Thanks again for all of the help. Even though
we have not found a solution yet I appreciate the help - and am still confident
we will succeed!
