TDM400 activate channels

I work at a small firm since 11 jan and they gave me the task to configure a “telephone server” (I don’t know if this is the it’s called in english)

i’ve installed asterix freePBX and all that… I’ve created trunks, outgoing/incoming permissions.
The problem is that it works just for 1 slot. If I move the cable in the next slot I can receive calls but I cannot dial. So probably I have toactivate the other channels, right? How can I do that?
I’m using a TDM400 (I don’t know if it’s TDM400E or P…)

Thank you very much. I hope you can help me.

P.S. I have to “connect” 2 mobile phone companies and a “home phone” company to the TDM400 to reduce the costs, but so far I can connect just one of them.
(sorry for my bad english…)

I found out that they were activated but group 0 had all the channels. So I modified in zapata.conf located in the /etc/asterisk/ ch 1 to group 0 ch2 to gr 1 and so on.

now it’s working
