I have a MD110, BC10 and want to connect it via TLU76/1 to an Asterisk server.
I found out that I need also a QSIG or ISDN-NET license to make this work.

My question is what ERICSSON part nbr I would need specifically.
For example the TLU76/1 is a ROF1375338/1 R8A.
What would be the part nbr for the required licence and what would be the part nbr for the cabling to connect to - let's say a Sangoma ISDN E1 card?

Any guide for the above scenario is welcome!
