It really depends what you will be hooking up to the asterisk box. If 
you are connecting to a telco's S0 bus you want the card to be in TE 
mode (Terminal Equipment). If you are using multiple ISDN lines that are 
coupled together as one bundle (ask the telco) you will probably neet to 
configure it as p2p. If all lines are singular, use p2mp.

If you will be connecting to a PBX, everything is dependant on how that 
PBX is configured.


Best regards,
