Subsystem Number
- Kelli Higdon
The Subsystem Number object pane is created under the SCCP/TCAP object. The Subsystem number along with the Point Code is used by SCCP to determine routing between a local application and a remote application. The Subsystem Numbers, which range from 0-255, can be selected through a drop down menu in the Subsystem Number Pane. From the subsystem number, the Adjacent Translator can be configured.

1 Subsystem Number object per SCCP/TCAP object.
Related Topics and Dependencies
To be able to access the Subsytem Number object, the SS7 stack being configured must have the SCCP field set to ANSI. By setting the SCCP field to ANSI, the SCCP/TCAP object can be created and the Subsystem object can be created under the SCCP/TCAP field.
