asterisk users - Dec 2003 - COnfiguring an * system for a non-profit organization

Hi,

Maybe someone has seen this before...

I've installed a new T100P, but it doesn't seem to work.  I've
attached
the T100P to an Adtran 750 using a crossover cable.  The Adtran shows a 
red alarm on the T1 interface.  The Adtran has been set to factory 
defaults with FXS cards in 1-3 and an FXO card in 5.

The T100P shows no signs of life--the leds are not lit.  Should I be 
seeing lights on the T100P?

Here is zaptel.conf:

loadzone = us
defaultzone=us
span=1,0,0,esf,b8zs
fxsls=1-12
fxols=17-20


This is the ztcfg (following the 'modprobe zaptel' command):

[root@localhost etc]# ztcfg -vv

Zaptel Configuration
=====================
SPAN 1: ESF/B8ZS Build-out: 0 db (CSU)/0-133 feet (DSX-1)

Channel map:

Channel 01: FXS Loopstart (Default) (Slaves: 01)
<snip>
Channel 20: FXO Loopstart (Default) (Slaves: 20)

16 channels configured.

ZT_SPANCONFIG failed on span 1: No such device or address (6)

I've found two different T1 crossovers specifications on the web. The 
first is:
1->5
2->4
4->2
5->1
The second is:
1->4
2->5
4->1
5->2
Neither work--the Adtran always shows a red alarm on the T1 interface.

Can you help me with this?  Is there some way to determine if the T100P 
is working or if it's DOA?

Thanks for your help,
Mike

Hi Mike-

Not sure why your card seems dead, but your second crossover spec seems to
be the correct one.

Here's a link to a good diagram of the crossover cable (see the bottom of
the linked page).  Only 1, 2, 4, and 5 are used.  It is not necessary to
connect the others.

Yes.  You probably have not loaded the drivers.  Try 'modprobe
wct1xxp', then re-run ztcfg.
