<br><font size=2 face="sans-serif">Hi,</font>
<br>
<br><font size=2 face="sans-serif">I'm having problems getting our server
to work with our BT ISDN30 box. We are using a Digium TE110P card
to connect to the ISDN box on the wall. The card is configured as
an E1 (strap on). I've made the T1 crossover cable ( well, made two
variations ) and neither work. The light on the Digium card flashes
red and the red LED's on the ISDN box stay lit. I've tested the configuration
and all modules load ok. Done a ztcfg -vvvvv and things look ok.
Done zttest and get around 99.7% - 99.9%. After loading asterisk
I did a zap show status and alert is red.</font>
<br>
<br><font size=2 face="sans-serif">After googling I found this statement:</font>
<br>
<br><font size=3>RED: Loss of signal (LOS): The equipment shall assume
"loss of signal" when the incoming signal amplitude is, for a
time duration of at least 1 ms, more than 20 dB below the nominal amplitude.
The equipment shall react within 12 ms by issuing AIS. </font>
<br>
<br><font size=2 face="sans-serif">The question is, is this a configuration
issue, cable issue or BT issue.</font>
<br>
<br><font size=2 face="sans-serif">Digium's site is down so couldn't look
there :-(</font>
<br>
<br><font size=2 face="sans-serif">One of the diagrams I used is here:</font>

<br>
<br><font size=2 face="sans-serif">The other diagram ( can't seem to find
that now ) used 1-5, 2-4 etc.</font>
<br>
<br><font size=2 face="sans-serif">Has anyone seen this problem?</font>
<br>
<br><font size=2 face="sans-serif">Thank you in advance.</font>
