The Message Switch software uses Simpact's Data Link Interface (DLI), which is a high-level, session-oriented application programming interface (described in the Freeway Data Link Interface Reference Guide).
There are several DLI configuration concepts that you must keep in mind when using the Message Switch software:
The DLI configuration file needs to include only those session parameters whose values differ from the defaults. Appendix B shows an example swdcfg DLI configuration file and swtcfg TSI configuration file for the Message Switch.
The Message Switch software uses DLI Normal operation. Therefore, each session must have the "protocol" DLI configuration parameter set to a specific protocol; for example:
protocol = "FMP"
If you are using a Simpact protocol in conjunction with the Message Switch software, DLI Normal operation allows you to define protocol-specific link configuration options in the DLI configuration file. Figure B-4 shows an example session configuration for FMP. Refer to your particular protocol Programmer's Guide for complete link configuration option details.
