Hi,
   Fortunately I had got a TE410P card and I used it with *. Everything is OK 
except that I have found the spans restarted once each hour. Just like:

Jan 31 10:42:37 VERBOSE[3266]:     -- B-channel 0/1 restarted on span 3
... ...
Jan 31 11:42:40 VERBOSE[3266]:     -- B-channel 0/1 restarted on span 3
... ...
Jan 31 12:42:44 VERBOSE[3266]:     -- B-channel 0/1 restarted on span 3
... ...
Jan 31 13:42:47 VERBOSE[3266]:     -- B-channel 0/1 restarted on span 3
... ...

Is this a timing problem? Thanks.



This is not a problem, or at least working as intended. Asterisk restarts all idle lines once an hour. This helps if the state machines on either end of the isdn link gets out of sync, thinking an idle line is not idle.


However, some pieces of equipment do no like these resets and drop all lines and not only those requested in the restart message. The interval can be adjusted with the "resetinterval" parameter in zapata.conf. To disable the resets it can be set to a huge value.

The network side of ISDN restarts idle channels. CPE side never initiate a restart. Asterisk should ignore the timer if is set as CPE.

Regards,

Gus
