This reports which HDLC addressing mode is currently in effect for satellite-interface frames, derived from the broader cdmipWorkingMode setting, determining whether addresses use 1 byte, up to 254, 2 bytes, up to 32767, or are not used at all. Because this is read-only and mirrors cdmipWorkingMode rather than being independently settable, an admin uses it to confirm which addressing scheme is actually active before interpreting the values in cdmipSatelliteHdlcAddress1 through 4, rather than assuming based on the working-mode setting alone. Reading this as smallNetworkMode(1) confirms that the modem's HDLC addresses, like cdmipSatelliteHdlcAddress1, are being interpreted as 1-byte values in the 1-254 range, not the larger range used in Large Network Mode.
