asterisk users - Nov 2004 - TDM22B - how to setup the extensions ??

I got this nice TDM22B with two green modules left and two modules right

/var/log/messages shows:

How do I design an extension for my two phones directly on the TDM card?

I just try to restart Astrisk, but it gives me:

[chan_zap.so] => (Zapata Telephony w/PRI)
== Parsing '/etc/asterisk/zapata.conf': Found

WARNING[9980]: loader.c:500 load_modules: Loading module chan_zap.so failed!
Ouch ... error while writing audio data: : Broken pipe


It seems I have something broken, but what and how to fix it?
