      It is an HLR.

      Probably a HLR (Home Location Register, used to store customers' account
      profiles -- phone number/ESN/IMSI associations, features, etc.)

      HP via its various acquisitions is pretty big in HLRs/VLRs; most SS7 core
      equipment (and especially STPs) are made by the usual telecom gear vendors
      like Nortel, Ericsson, Tekelec, etc.
