hey * folk,

i've got a TE410P (generation 1 firmware) stuck in a box with a single xeon
2.8Ghz and 1GB RAM. there's a loopback E1 cable connecting span 1 to span 4
(zaptel.conf and zapata.conf below). upon starting up asterisk, i see the
following errors consistently on the screen,

!! Got I-frame while link state 2
!! Got a UA, but i'm in state 1

they seem to be coming from libpri.so.1 and the spans seem to be restarting
each other infinitely. i also get a number of the following messages from
chan_zap.so:

B-channel 0/6 restarted on span 1
B-channel 0/6 restarted on span 4
B-channel 0/7 restarted on span 1
B-channel 0/7 restarted on span 4
B-channel 0/8 restarted on span 1
B-channel 0/8 restarted on span 4
B-channel 0/9 restarted on span 1
B-channel 0/9 restarted on span 4

No D-channels available! Using Primary Channel 16 as D-channel anyway!
No D-channels available! Using Primary Channel 109 as D-channel anyway!

both spans show "Provisioned,Up, Active" in pri show span, and zttest
shows
100% all the way.

a snapshot of pri debug span 1, shows:

any idea what could be causing this ? it doesnt really matter which of the
two spans i loopback on, the symptoms remain the same. needless to say, no
calls can be made.

asterisk and libpri are CVS HEAD as of 12 oct 05.

could it be due to a buggy card ? if this is the case, i really wont be
able to tell as i dont have any spare cards to test with. i've read that
the newer versions of the drivers may cause similar problems to old cards,
but since we're on freebsd, we're unable to revert to an old version of
the
driver.

i'm very close to escalating this to digium support, but am wondering if
someone here has seen this and/or solved this before.

additionally, what are the usages of pridump, pritest, testprilib
respectively in the libpri sources ?

[Asterisk-Users] E1 PRI error: "!! Got I-frame while link state 2" and "!! Got a UA, but i'm in state 1" (long)

Have you tried this in a Linux machine or are you still trying this in  
your FreeBSD box?

This boils down to "I'm trying to start up the link, but the other side
seems to think that it IS up".

In an earlier post you showed that you had some spans set for internal 
clocking, some for external.  If you are using loopback cables, I'd 
suggest setting all the spans for internal (X,0,0,ccs,hdb3[,crc4])

Make sure nothing else is connected on the PRI, just the loopback cable.  
And the loopback wiring is the pair on 1/2 crossed over to the pair on 
4/5.

The part you posted is just where Asterisk is restarting each B-channel.  
More useful would be the part corresponding to the debug messages logged 
above.

I'm not sure how old your card is, but I routinely run the CVS-HEAD 
zaptel/libpri/asterisk on generation 1, "version 10" cards.

Unusual order here.  I've always followed the sample and put the span 
definitions at the top and the bchan/dchan following.

Also, see the comment about the "1" for taking clock - rather make it
0
for loopback tests.

(You've also asked for two primary sync sources, which isn't right).

Did you leave out the other two spans in your zapata.conf?

Its a bit unusual to put both spans in the same group - calls to Zap/g1 
may use any channel on either of the spans.  Is that what you want?
And immediate=yes is probably not what you want for an ISDN link.
