6. Multiple supervisors

If RSMP version 3.2 or later is used then the TLC needs to support multiple supervisors according to section 4.3.1 Multiple supervisors in the RSMP specification.

The TLC needs to support at least three (3) RSMP connections to different supervision systems simultaneously and handle concurrent communication with all of them.

For example, a traffic light controller might connect to both a traffic management system and a bus priority system. Or it might connect to both a traffic management system and a secondary monitoring system.
