NAT Address

A static IP address used outside of the firewall for remote access to the MPS. Static address mapping makes systems that are behind the firewall appear to have public addresses on the external network. A one-to-one mapping exists between internal and external addresses. An external address must be assigned to the NAT firewall for each MPS side. The external addresses must be entered into the MPS database in order for the Web user interface to be fully functional.

Non-ANSI Domestic Point Code

A point code format used in the United States that does not meet the ANSI standard, but does not use the ITU international or ITU national point code formats. The non- ANSI domestic point code is made up of three groups of digits called network, cluster, and member, just like the ANSI point code. The values for each of these groups are from 0 to 255.

Non-Specific Binding Correlation Key

A binding correlation key value that is specified in more than one binding capable session initiation request is considered to be a non-specific binding correlation key. Non-Specific Binding Correlation Keys are generally associated with the subscriber vs. being associated with a particular session. IMSI and MSISDN are examples of nonspecific binding correlation keys because multiple sessions may exist concurrently with the same IMSI or MSISDN value. IPv4 and IPv6 addresses are not “non-specific” because each binding capable session is expected to have its own unique key value.
