Geographically dispersed processors communicate using the network job entry (NJE) facility for the purpose of transmitting commands, messages, jobs, and job output between the host systems (System i®^* JES2, JES3, VM/RSCS, and VSE/POWER). The facility can also provide communication among processors at the same location as an alternative to a JES2 multi-access spool configuration. An NJE network can consist of up to 32,767 nodes. Each of the nodes can be either a single processor or a multi-access spool (MAS) configuration. An MAS configuration is one in which as many as 32 members share one set of JES2 spool and checkpoint volumes. NJE can also communicate between primary and secondary JES2 members on the same processor.

NJE is compatible across all releases of System i, JES2, JES3, VM/RSCS, and VSE/POWER.
