asterisk users - Sep 2004 - Newbie - Troubles after installing e100p

Hello

I's trying to install an asterisk-server with a wildcard e100p and get
some errors while starting asterisk:

Sep  1 18:49:34 WARNING[1024]: chan_zap.c:724 zt_open: Unable to specify
channel 1: No such device or address
Sep  1 18:49:34 ERROR[1024]: chan_zap.c:5883 mkintf: Unable to open
channel 1: No such device or address here = 0, tmp->channel = 1, channel
= 1
Sep  1 18:49:34 ERROR[1024]: chan_zap.c:8792 setup_zap: Unable to
register channel '1'

The wildcard is connected to an local pstn. I first had troubles with
the signalling after solving this, the failures came up instead...

I'm quit sure that i'm doing an obvious failure but even after reading
the wiki-pages for hours i'm not able to find the error.

Best regards
