L1 und L2 Link down

Hallo,
ich probier schon seit Tagen asterisk zum Laufen zu bekommen. Die Konfiguration ist zunächst ganz einfach:
ISDN-Telefon->NTBA1->Kreuzkabel->ISDN Karte (port2) im NT Modus->Asterisk->ISDN-Karte (port1) im TE Modus->NTBA2->externer ISDN Anschluß (von Hansenet).
Beides sind HFC Karten
Ich hatte es zunächst mit bristuff schon so weit dass der interne Anschluß im NT Modus funktionierte, aber der externe nicht, deshalb wollte ich es jetzt mit misdn probieren.
Nun funktioniert aber gar nichts mehr.
Als Fehlermeldung bekomme ich:
*CLI> misdn show stacks
BEGIN STACK_LIST:
* Stack Addr:40000104 Port 1 Type TE Prot. PMP L2Link DOWN L1LinkOWN Debug:4
* Stack Addr:40000201 Port 2 Type NT Prot. PMP L2Link DOWN L1Link:UP Debug:4

Wenn ich versuche von extern anzurufen, kommt die automatische Ansage des Telefon Providers.
Wenn ich von intern (von einem sip -softphone) versuche nach draussen zu telefonieren, kommt:

Ich hab jetzt keine Idee mehr, wo ich noch ansetzen kann , um das hinzubekommen. Die Kabel und Hardware sind alle ok und gecheckt.

Hier sind noch die Konfig Dateien:
