Hello,
Thanks  to members  of  the  list things  changed  on my  installation
(asterisk + digium E100P with of course an E1 line). 
Here is my zaptel.conf :
-
span=1,1,0,ccs,hdb3
bchan=1-15,17-31
dchan=16
loadzone=fr
defaultzone=fr
-
Output of zttool:
-
   Alarms Span 
   YEL/RED Digium Wildcard E100P E1/PRA Card 0
-
 
[root@asterisk root]# head /proc/zaptel/1

There's  a blinking  red led  on the  E100P, previously  there  was no
light at  all, so  i guess  something changed even  if it's  not still
working, but i'm on the right way :)
any help would be greatly appreciated. 
Thanks.
