part 2: when MSC sends signal to HLR via route MVS, it is up tp the HLR to define what the dialed digits mean…transfer busy (TRB), transfer no reply (TRN), call waiting (CAW & ENQ) etc
most common is stand alone HLR. above is still the same for co-located HLR in AXE (I have not seen co-located HLR in 7 years in North America..mostly Compaq/Tandem telecom)
