This read-only object reports whether an IP Controller card is installed: none(0) or installed(1). This is a hardware presence flag distinct from the modem's own management IP address, cdm570IpAddress -- it specifically indicates whether the unit has the optional card that adds native IP framing/routing capability to the satellite data path itself, as opposed to just SNMP-manageability over the terrestrial Ethernet port, which every unit has regardless of this option. A site needing to carry routed IP traffic directly over the satellite link, rather than a raw serial data circuit, would need to confirm this object reports installed(1) before that capability can be used.
