| NSAP-Selector (NSEL) is part of the
NSAP address field that identifies a process on the device. It is roughly
equivalent to a socket or a TCP port number in TCP/IP. The NSEL is not used in
routing decisions. Domain-Specific Part (DSP): comprised of the HODSP, the
system ID, and the NSEL in binary format. The last byte is the N-Selector
(NSEL) and must be specified as a single-byte length preceded by a
'.'. A NET definition must set the N-Selector to ’00’. See also
NSAP Address, NET.
