Description:Something is going on with the timing with the current version of the zaptel / wct4xxp drivers...  This causes the remote end to send us yellow alarms, which causes all in-progress calls to be dropped.

****** ADDITIONAL INFORMATION ******

With zaptel from 3/15, the following messages are logged on the console:

Zapata Telephony Interface Registered on major 196
PCI: Found IRQ 5 for device 00:04.0
Found TE410P at base address fd000000, remapped to e0975000

Registered tone zone 8 (Norway)
TE410P: Span 1 configured for CCS/HDB3/CRC4
SPAN 1: Primary Sync Source

With zaptel drivers from 3/30, this changes to:

Zapata Telephony Interface Registered on major 196

Found a Wildcard: Wildcard TE410P-Xilinx
Registered tone zone 8 (Norway)
TE410P: Span 1 configured for CCS/HDB3/CRC4
SPAN 1: Primary Sync Source

Note that the difference between these two are the single line that says "TE410P: Timing from source X", which on the current version of zaptel says "4", and the one from 3/15 says "0".

The only span that is configured in zaptel.conf is span 1, which is set up with "span=1,1,0,ccs,hdb3,crc4".  Spans 2, 3 and 4 are not configured at all.  Spans 1, 2 and 3 are jumpered for E1 while span 4 is jumpered for T1.

The rest of zaptel.conf (aside from comments) reads:

bchan=1-15,17-31
dchan=16
loadzone=no
defaultzone=no

To reiterate, the system works fine with zaptel dated 3/15, and gets yellow alarms with zaptel dated 3/30.

Please cvs update to latest zaptel.  I've put some changes in this morning which should also help.

Hi,

  I have exactly the same problem. I rolled back the CVS to 2004/03/05 and everything come back to normal. With current Zaptel I saw the same "Timing from source 4" message as tholo and with 2004/03/05 I saw "Timing from source 0".
  I also got a Yellow alarm and Asterisk reset the channels with the lost of all current conversations.
  I attached a Cobra PRI monitor and I saw constant Sync Errors.

.. but the problem remains, I still get yellow alarms and call drops.

Oh, and zttool changed from showing "Internal timer" to saying it was getting timing from span 4...

Try me again on IRC.  I got disconnected last time.
