Figure 4-22: CN Configuration Window – MSC/IWF Properties
Navigate between the windows by selecting one of the buttons along the left edge of the
window. Figure 4-22 shows the MSC/IWF Property window after it has been selected.
The MSC/IWF Property window configures call authentication and inter-working
functions. For call authentication procedures, the RANDU and RANDSSD variables can be
entered, as well as the A-Key. If the Mobile Station under Test has registered, AirAccess
displays the proper A-Key checksum when a new A-Key is entered. Additionally, Shared
Secret Data (SSD) displays on this tab after it is calculated by AirAccess.
NOTE: AirAccess supports SO12 (Quick Net Connect) calls only. Async Data Calls are
not supported.
The PDSN Property window is shown in Figure 4-23. AirAccess can emulate Simple IPv4
Only, Mobile IPv4 Only, Mobile IPv4 Preferred, Simple IPv6 Only, and Simple_IPv4_v6
Only. When Mobile IP Preferred is selected, the PDSN falls back to a Simple IP
connection if Mobile IPv4 service cannot be established. If Simple IPv4_v6 Only is
selected, the PDSN can support IPv6CP protocol to negotiate a unique Interface Identifier
and IPCP protocol to negotiate an IPv4 address in one PPP setup procedure while
simultaneously supporting IPv4 and IPv6 traffic flow.
