Entity and instance IDs

Each application must have a unique entity and instance ID to route messages among the various processes in the system.

Entity IDs are single byte values in the 0x00 to 0x3f range, assigned by the application developer. Allocate entity IDs as follows:

Range

Usage

0x00 - 0x1F

Reserved for system utilities, configuration utilities, and management utilities.

0x20 - 0x3F

Reserved for applications.


Instance IDs identify the processor on which an entity executes. The host is always processor 0 (zero). For all host-resident NA SS7 Monitor Software user applications, the host instance ID is always 0 (zero). All tasks on TX board number 1 receive an instance ID of 1, all tasks on TX board number 2 receive an instance ID of 2, and so on.
