Defining a minimum configuration for BSC NJE

During JES2 initialization, you can easily request the NJE feature. The default configuration (shown in Figure 1) is a very simple BSC-only network. Include four JES2 initialization parameters, NODENUM=, LINENUM=, and OWNNODE= from the NJEDEF statement and the UNIT= parameter from the LINE(nnnn) statement, in your initialization data set. The LINE(nnnn) statement specifies the device address of the line (UNIT=) and enables the text transparency feature (TRANSPAR=), that is, the feature that allows JES2 to send all 256 characters in a data stream without the data being interpreted as control characters.

NODE 1 in Figure 1 defines NEWYORK1 as the first node in the network. NODE 2 in the figure does the same for the second node (WASHDC2). The simple network illustrated in Figure 1 shows how to use the NJEDEF statement parameters: NODENUM=, LINENUM=, and OWNNODE=. JES2 uses default values for the remaining NJE parameters.
