[Asterisk-Users] E400P woes

[Alastair Maw]

We've changed E1 providers and I'm trying to reconfigure an E400P to 
make it work with the new lines. They're supposedly "standard" EuroISDN 
lines (in the UK). I'm initially just trying to get a single line up.

I have the following in /etc/zaptel.conf:

   span=1,0,0,ccs,hdb3
   bchan=1-15
   dchan=16
   bchan=17-31
   loadzone=uk
   defaultzone=uk

The LED on the back of the card shows red/green simultaneously when you 
ztcfg it.

Asterisk itself spews messages to the console like so:

   == D-Channel on span 1 up
   == D-Channel on span 1 up
   == D-Channel on span 1 up
   == D-Channel on span 1 up
   == D-Channel on span 1 down
   == D-Channel on span 1 up
   == D-Channel on span 1 up
   == D-Channel on span 1 up
   == D-Channel on span 1 up
   == D-Channel on span 1 down

(Always four ups and then a down a bit later, followed by a pause, then 
the same again.)

Changing span=1,0,0,css,hdb3 to use crc4 causes Asterisk to throw lots 
of yellow alarms when it starts. Putting a 1 in the timing field makes 
no discernable difference.

The guy who tested the lines isn't very clueful - he just plugs in his 
gear and puts a tick in the box, but he's pretty sure it uses hdb3 
coding. CAS framing makes the LED go RED.

Anyone give me a clue here?
