12 Chapter 12. Non-SNA Interconnection (NSI) IBM Product Number: 5668-951 This chapter discusses alternatives to the NSI support for communication between binary synchronous communication (BSC) remote job entry (RJE) devices and host applications across an SNA network. Note: In addition to the technical solutions discussed in this chapter, you should also consider the alternatives of eliminating the IT service in question or replacing that service with a completely new solution.
