If configuring a service such as CNAM or MWI on multiple IMG nodes, the SS7 Stack ID's cannot be configured with the same ID. For example, when configuring an IMG Node 0 with stack ID's 0 and 1 then any other IMG Nodes configured under any Logical Node can not have any of the stacks configured with the same ID's (0 or 1). By doing so, the TCAP services cannot be configured. |
