Can't figure out what hardware

Hi all,

I’m living in The Netherlands and have ISDN (two lines).
What hardware can be used best when I want to connect one ISDN line to my Asterisk box and one or two analog phones.

To connect phones, I thought I need something like the TDM01B or TDM02B. (correct me when I’m wrong) but I can’t figure out what I can just best to connect the outside ISDN line.

Thanks.
Onno.
