[Asterisk-Dev] T1 Card testing

How do I setup zaptel.conf and zapata.conf to get this setup to work
I have a T400P and I made a crossover cable
zttool gives me a OK on both spans




Not sure what to use in zapata.conf though.

Lines and trunks can not be connected directly together.

There are two types of lines fxo and fxs. I assume that this fxo/fxs is 
what you meant. Having said that, it will work fine to connect one T1 
to another T1 of a T400P card. You would just need a normal T1 
crossover cable.
