asterisk users - Dec 2009 - Is this bad hardware? Dahdi-v-X100 clone

I've spent a week playing with Asterisk 1.6 and I love it. What a
brilliant piece of software!

Progress and learning have been reasonably good. I have external SIP
provider calls coming in and have put together a little call platform
and I'm stunned at the flexibility.

There is one issue for me. I took me a while to click that ZAPTEL now
equals Dahdi, but now I'm there I have an issue with the a X100 clone
card that I have been told *not* to mention as I'm guaranteed a hostile
response :-< So, I've put on my flameproof pants to ask a simple
question:

dahdi show status gives a red alarm. I'm guessing this means the card is
unable to detect the battery. I've plugged a test but into the loop
through on the card, dialtone is there. I've tried reversing the
polarity, two way/three way jack leads (I'm in the UK) but none the less
I get:

Description                              Alarms  IRQ    bpviol CRC4
Fra Codi Options  LBO
Wildcard X100P Board 1                   RED     0      0      0
CAS Unk  YEL      0 db (CSU)/0-133 feet (DSX-1)

Is this likely to be bad hardware (hostility towards this cheap card
noted) or software/driver?

It would be just ace to crack this problem and learn some more.

Thanks
Bob.

Getting dialtone on the passthrough port (it's passthrough, not loopback)
doesn't tell you much, as the pins are usually hardwired between the two
jacks.  Generally, what we tell people here who are having hardware problems
are to contact their reseller for support.  That's true, whether the cards
are
Digium, Sangoma, or a cheap clone.  However, given that cheap clones generally
have no support system, it's interpreted as hostility when we cannot offer
any
particular help.

I have never used that card myself, but I have never seen an analog board
reporting a RED alarm. Probably there is something incorrect in your
configuration. Please post your /etc/dahdi/system.conf and
/etc/asterisk/chan_dahdi.conf.

Ahem. Wcfxo always has (AFAIR). "Red alarm" means that no line is
connected (it gets no current from the remote FXS in the central
office).

Later on most DAHDI drivers of FXO ports started to use this signalling
(though for the specific port rather than for the whole span).

If you connect a standard analog phone instead of that card and get a
dial tone, something is fishy with the card (or the driver) as it is
mis-reporting.
