and PPP topologies will use the PPP protocol. The column titled “AP Role” is used to specify
whether the AP will terminate PVCs from the SU or switch them through to another termination
point. This is only pertinent to the AP upgrade. The fourth column, “System Mode”, refers to
how the unit will act in the network. A unit in static mode will not try to register with the
Element Management System but will instead use the configuration files found in the Flash file
system. A unit in interactive mode will automatically try to register with EMS (dynamically) via
the AP with the strongest RF signal it can detect. Installation mode, used for SUs only, places
the SU is a mode which will ultimately allow it to register dynamically, but upon first boot, the
unit requires manual intervention to complete its RF alignment. The last column, “Interface”
defines the type of terrestrial interface the unit will use after reboot. This is important to note
since improper configuration selection will change the terrestrial interface type. This may make
the unit appear unreachable after reboot.
With every release, be sure to carefully look over the configuration option file, as new options
are occasionally added. To reset a unit to factory defaults, an AP should be upgraded to
configuration #4 and an SU to configuration #1(reference Tables 1-1 and 1-2).
