Address translation is also done for cross-network SSCP-SSCP sessions. Each LU and SSCP with which you want to have a cross-network session requires at least one element address. The number of addresses that can be used to represent cross-network resources within a given network depends on the following situations:

• If extended network addressing is used, 32 768 element addresses can be used to assign alias addresses.
• If nonextended network addressing is used, the element pool is determined by the MAXSUBA specification. For example, if a network has MAXSUBA=63, each subarea can have at most 1024 element addresses.
