This attribute specifies five different NSAP prefixes which are
distributed to all other Passport nodes within a Topology region and
by which this node can be identified. PORS calls that use NSAP
addressing (for example, CES) will look for the node with the
longest NSAP prefix that matches the called party address. The
default value of the nodeAddressPrefix under the AtmPnni
component is formed by the first NSAP prefix followed by a unique
MAC address. Each NSAP prefix may contain 40 hexadecimal
characters with the exception of the first prefix which has a
maximum length of 26 chracacters.
This attribute was never deployed and will be removed prior to Gate
2..
