asterisk users - Dec 2004 - Two zaptel T1 cards: no clock from one

List,

I have a TE410P (T1 mode, all PRI) and a T100P (fxoks, for fxs channel
bank).  I cannot seem to get the T100P to send any clock to the
channel bank.  I prefer that it use the same clock source as the
TE410P, but it doesn't matter if it's not in sync just as long as
it's
there.

The TE410P is configured 3x pri_cpe, 1x pri_net.  The three cpe go to
XO Sonus switch, the net to legacy PBX.  Clock is received from telco,
old PBX receives clock from zaptel card, everything's green there, but
the other card, the T100P, seems to not send any timing at all, as
verified by our T1 analyzer, and is persistently in red alarm.  In
fact, even if I stick a loopback plug in the T100P, the alarm persists
(loopback causes a result in the TE410P).  The T100P and channel bank
were just pulled from another working * box, and the configuration is
nearly identical, except it was the only T1 interface.

System: Supermicro dual Xeon 2.4, both cards on same PCI bus.
Cards: one T100P, one TE410P.
Config: spans 1-4 for quad card (module loaded first), span 5 is
single port card
Channel bank: Access Bank II, 12 FXS

I have a similar issue. I am trying to get two TE410Ps to operate 
together correctly on the same box. The first card has operated well 
for months. The other is always reported as "internally clocked" no 
matter what I do. I used to run on RedHat 8.0 (old, I know) and it was 
not until I moved to FC2 (kernel 2.6) the system became stable. Also, 
you have to make sure the Digium boards do not share interrupts with 
anything else. Confirm with cat /proc/interrupts. I have no experience 
with multi CPU systems, but from your output it seems that the IRQs are 
indeed different.

The problem persists in my system. The second card reports no clock. 
However, the devices attached to it work consistently and I don't get 
regular IRQ misses anymore. I say regular because with RH8 IRQ misses 
for the new card would show up all the time. Now they only occur under 
heavy network activity, such as copying a very large file from another 
server.

Yeah, proper crossover cable.  I've eliminated all cabling issues with
the T1 analyzer.  I get a full and accurate pattern back when I test
from the cable end where it would have been connected into the T100P,
with the channel bank in loopback.  The main symptom is that when I
hook the analyzer directly to either the channel bank or the T100P,
neither is providing clock.  I could have the channel bank supply one,
but I will have fax/modem calls bridged between the two PCI cards, so
a common clock is best.  The most disturbing thing is that the T100P,
as the only card in a system, provided clock just fine.

There was a thread last month in -dev about being unable to use common
clock source across cards.  Is this related?  How can one cause zaptel
to provide ref clock?  Should I be seeing 1000 interrupts/sec on any
and all TDM cards?

Since Span 5 is a channelized T1 make sure the last two parameters match the
settings for the chan bank(esf & b8zs).  You cann't remove timing from a
T1.
You can only make YOUR card take timing from the incoming digital signal,
take timing from another T1 on the same card or supply it's own internal
timing. (these cards do not pass timing between cards from what I have read
here.)

My gut reaction is that something else is wrong.  I also noticed in your
debug output that span 1 through 4 were represented, but span 5 does not
show up.

What about ztcfg and zttool outputs?
