[Asterisk-Users] T100P + Adtran TSU600 + FXO and caller id problems

[Marcin izo]

I have following setup

Asterisk - T100P -> Adtran TSU600 P + FXOcard ->  PSTN line

When PSTN line is plugged directly in to analog X100P caller id is
received by Asterisk
but when I plug it into adtran I'm not getting caller id.

Any ideas what kind of setup Adtran TSU600 requires to pass caller id
to T100P ???
