      @funkylab I don't have a clear indication of the year yet either, sorry. Given it has TAE-8 (Bu5, used in national 1TR6 ISDN) and UAE8/8P4C (Bu4, used in EDSS1 Euro ISDN), I guess it must be at a time when both were popular. So I'd guess 1992 onwards?

      @LaF0rge I'm having a hard time putting a year to this: Obviously, pre-1993, due to the old post code, probably pre-1991 due to the "made in W-Germany", the English labelling says "(E)DSS1 era", i.e., post-1991?, the plastic colour makes it a "modern look" from the mid-1970s to the late 1980s, so a Siemens-modern look probably mid-1980s to late 2000s.
      8P8C Bu4 puts it proooobably more on the modern side, and whatever Bu6 is.
