Dear Sir or Madame,
sorry for writing you in English, but my Dutch isn't good enough for writing (I can read and understand quite well).
3rd time within 2 years my ISDN telephone line is just dead. Happend 5 days ago. Internet is still working, so it's either the NT1 or the splitter. ISDN device is operated without a "centraale", and I've tried 2 of them - with same result.
Last time it was the NT1, and the technician replaced it by a used 2-port NT1 (1 port working, one port broken). The "line ok" light is currently on (green). The 230V light is not on, so I guess it's serviced over the line, since there is no cable going to a 230V wall outlet.
I need your assistance.
Besides that I don't need/want ISDN any more, so after fixing my problem I either will switch to a different supplier (like cable) or to a different contract with KPN. As a software developer I need better internet bandwidth and a reliable telephone.
