asterisk users - Mar 2005 - Single port S0 ISDN card to use in Greece

Hello to all,

I'm trying to build a PBX using Asterisk. I have a single BRI ISDN
line and I need to connect 4 internal normal phones and a couple of
softphones on PC. I have bought a single port Billion S0 card and a
TDM400 with 4 FXS modules for the intenal phones.
ISDN lines here in Greece terminate to an NT1 terminal called NetMod
(http://www.intracom.gr/en/products/terminal_equip/isdn_netcon_netmod.htm).

My question is should I operate the billion card in TE or NT mode?

Anyone with relevant experience please help.

Thanks in advance

To connect to the phone network it should operate in TE mode. TE is short 
for Terminal Equipment i.e. anything you connect to the pstn.
