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?
