asterisk users - Jan 2004 - Fun (or lack of) with asterisk & T100P

Hello,

I'm trying to get a Wildcard T100P working with Asterisk and so far I 
haven't had any luck.  No problems with the card itself from what I can 
see and the telco says that the problem is on our end (don't they 
always?).  A small sample of what asterisk spews out on the console:

Jan 13 15:45:32 WARNING[180236]: chan_zap.c:5834 zt_pri_error: PRI: 
Read on 43 failed: Unknown error 500
PRI got event: 5
Jan 13 15:45:36 WARNING[180236]: chan_zap.c:5834 zt_pri_error: PRI: 
Read on 43 failed: Unknown error 500
PRI got event: 6
Jan 13 15:45:36 WARNING[196621]: chan_zap.c:4781 handle_init_event: 
Detected alarm on channel 1: Red Alarm
Jan 13 15:45:36 WARNING[196621]: chan_zap.c:4781 handle_init_event: 
Detected alarm on channel 2: Red Alarm
Jan 13 15:45:36 WARNING[196621]: chan_zap.c:4781 handle_init_event: 
Detected alarm on channel 3: Red Alarm

(repeated for channels 1-23)

A few seconds later the alarms are all cleared:

Jan 13 15:45:41 NOTICE[196621]: chan_zap.c:4776 handle_init_event: 
Alarm cleared on channel 1
Jan 13 15:45:41 NOTICE[196621]: chan_zap.c:4776 handle_init_event: 
Alarm cleared on channel 2
Jan 13 15:45:41 NOTICE[196621]: chan_zap.c:4776 handle_init_event: 
Alarm cleared on channel 3
(repeated for channels 1-23)

A few seconds after that the warnings appear again.  The T100P has an 
IRQ to itself, all nonessential stuff has been ripped out of the kernel 
(2.4.23 on Red Hat 9) and I'm using zaptel, libpri and asterisk 
versions checked out of cvs today.  zaptel.conf and zapata.conf file 
contents follow... framing, coding, and switch type were provided by 
the telco.   Any help or at least a kick in the right direction would 
be greatly appreciated!

zaptel.conf:
span=1,1,0,esf,b8zs
bchan=1-23
dchan=24
loadzone=us
defaultzone=us

zapata.conf:
[channels]
switchtype=national

signalling=pri_cpe

pickupgroup=1
channel => 1-23
