here you are the fax cable has the same end - that connected to the router has an additional tae adapter placed on the hp supplied cable. the fax cable end attached to the printer is attached to the1-line port as directed by the hp representative. who also said he couldn´t help me any further- I had to conntact a telekom rep- still no answer after almost 2 weeks.

that´s the cable that was with the printer and the instructions state that one should NOT use another. In the user manual one is told to contact the network provider for an adapter for a digital voip connection. unfortunately Deutsche Telekom doesn´t seem to have an interest in talking to me about this matter and hp says they´re not responcible for helping me- I  should contact my network provider.

I can´t use the cable that came with the printer without aTAE adaptor. That´s why I´m attempting to use it. THe cable looks like an isdn cable on both ends- although (according to HP) the fax is analog.

thanks for your help. the problem is solved.- I purchased a new fax tae cable from mediamarkt and it worked like a charm. sorry for the trouble I caused but 'I do appreciate your time and assistance. later!
