<div>I keep getting a red alarm when trying to setup asterisk to use
my TE420B EC. I only have a blank context setup in my extensions.conf
as I haven't started to config that until I can clear this red alarm.
I don't have physical access to the server, so I can't go reseat the
modules/card/ethernet cable, though I have hands on location that have
done this a couple times already. Please help. I'm quite frustrated
at this point. Thank you in advance for any help.</div>

As I see you have specified nl as defaultzone so I expect that you are
using a ISDN-30/15 line from provider KPN in the Netherlands.<br>
If so then remove the crc4 option from the span line in
/etc/dahdi/system.conf. <br>
<br>
<div><b>/etc/dahdi/system.conf</b></div>
<div>
<div># Span 1: TE4/0/1 "T4XXP (PCI) Card 0 Span 1" (MASTER) </div>
<div>span=1,1,0,ccs,hdb3</div>
</div>
bchan=1-15,17-31
<div>dchan=16</div>
<div>echocanceller=mg2,1-15,17-31</div>
<div><br>
</div>
<div># Global data</div>
<div><br>
</div>
<div>loadzone = nl</div>
<div>defaultzone = nl<br>
<br>
KPN is not using the crc4 checksum and therefore the card is not
getting the wrong checksum on the lines and so they get a red alarm
status.<br>
After the change reload dahdi and your lines should change colours.<br>
<br>
If this is working for you please answer to the mailing list so people
in the future will find it. The next time please specify the type of
telephoneline and provider.<br>
<br>
