2.2.2.6 Security Configuration
Figure 2.2.2.6-1: Security Configuration Fields
The Security functions allow the administrator to enable or disable the NOMAD MXU. If disabled (box
not checked), the NOMAD MXU will ignore all Iridium call attempts except a call from the NOMAD
MXU Configuration Manager program. The administrator can set a timeout feature that causes the
NOMAD MXU to disable itself if the administrator (using the MCM program) does not contact it within
the specified number of days. Whenever the MCM program successfully contacts the NOMAD MXU, the
Last Security Poll field will be set to the current UCT (Universal Coordinated Time). This "resets the
clock" and the timeout period will begin counting again.
