The best people to ask for the first three are Tata. Second best are the vendors of the ISDN card.

For the remaining two, if “in” is an acceptable value, use that.

Since even after getting the answer to the questions you still have an unspecified issue _and_ you purchased a card, you should be able to contact the support department of your card vendor with help in initial setup.
