Field Descriptions:

Stack ID (10.3.3)

This field specifies the ID of the stack. Under each Physical IMG ClientView supports configuring 4 stacks. The stack ID's can be set from 0 – 3. See "An Overview of SS7 Signaling" in related Topics above for more information

Stack ID (10.5.0)

This field specifies the ID of the stack. ClientView supports configuring a maximum of 16 stacks. Under each Physical IMG object ClientView supports configuring a maximum of four stacks. See "An Overview of SS7 Signaling" in related Topics above for more information.

 

SS7 Variant:

This field specifies the variant used for the stack.

Select from drop down menu either Use Base Variant or if there are any custom SS7 variants configured, they will be displayed in the drop down menu to select from. If using an SS7 Variant the ISUP field will automatically get populated with what was configured in the custom variant.

 

Note: Once a custom variant is assigned to a stack, you cannot modify or delete an existing entry in the variant. You can add new entries, however.

 

ISUP:

If Base Only is selected in the SS7 Variant field above, you will be able to select from drop down menu the ISUP variant. Variants shown in table below. If a custom variant is created, this field will default to the ISUP variant configured in the custom variant.
