Referring again to Figure 1, including the NJEDEF parameters LINENUM=, NODENUM=, and OWNNODE= in the JES2 initialization streams of these two systems created an NJE network. Because only these NJE options appear on the statements, JES2 uses default options for the remaining NJE parameters. These options provide the capability to send and receive data, detect lockout situations, route output, specify the difference between TOD clocks at each node, and provide command authority.
