[Asterisk-Users] problems with a pri (E1)

[Xavier Gil]

Hi all,
Our asterisk PBX, randomly restarts all the channels of the E1 connection. It sends this message
"There is no D-Channel, using channel 16 anyway".Then  the asteisk recive (or it thinks it
recives) yellow alarms at all the B-channels, after that it restart all the channels. When
restarting the B-channels it cut all the conversations that is handling at that moment. Does
anyone have an idea for what it is happening?
We run a asterisk 1.2.1 on a HP Proliant ML310, PIV 3Ghz 2 Mb L2 cache, 1 Gb Ram. We have a TE210P
digium card configured for E1. 

This pbx has been running for almost a moth before giving this problems, we have called our telco
and seens that in their side all is ok. (Our telco is ONO- Spain)

This is the zaptel.conf 

span=1,0,0,ccs,hdb3,crc4,yellow
bchan = 1-15,17-31
dchan = 16
 

# Global data
 
loadzone        = es
defaultzone     = es

this is the zapata.conf
