Hi DietmarF,
in my OM there is ALC-GM with and without Doughter board.
I think you need without, boardtype 06 and signalling 3210, HW-Type 255 (like other older ALC-G).
It is no problem, all PCT to assign with 3205, or change to 3205.
Since more than 10 years I have to do with Sopho, and all signalling are today valid, while boards were changed.
Try it, and you will see, it works.
I hope it is usefull.
Have a nice Weekend
Merry Christmas and a happy New Year! to you and all people here in this Forum.
Frohe Weihnachten und einen Guten Rutsch in das Neue Jahr.
