Do not copy without express permission of Honeywell.Page C--11Table C--1. ORT Characteristics (cont)ORT Item DescriptionAttributesCharacteristicil MasteryHandoverAlgorithmWeightingUser,commonThis item stores the relative weighting factors for each of thesix functional capability items that form the criteria fordetermining which system should automatically become themaster in a dual system. Each of the six weighting factors is anon-negative integer ranging from 0 to 99. Higher factorsindicate more important criteria; however, only the relativevalues of the factors is significant. Zero is used to indicate acapability factor not installed, not used, or is a don’t care. Thefunctional capability items are as follows:•CoV -- Cockpit voice (for any number of channels).•CaV -- Cabin circuit-mode voice/fax/data(any number of channels, any cabin interface).•CoL -- Cockpit packet-mode data(through [C]MU) at low-rate only.•CoH -- Cockpit packet-mode data(through [C]MU) at (potentially) high-rate.•CaL -- Cabin packet-mode data(through CPDF or CTU) at low rate only.•CaH -- Cabin packet-mode data (through CPDF or CTU) at(potentially) high-rate.CoL and CoH are mutually exclusive, as are CaL andCaH — i.e., regardless of the weighting factors assigned, nomore than one of the cockpit data (or cabin data) capabilitiescanbetrueatatime.The primary practical use of this ORT item is for determiningwhich SDU in a dual system should be the master when thechoice is down to one system which only has voice capabilityvs one which only has data capability, or one with only cockpitservices capabilities vs one with only cabin servicescapabilities.lDisable/ReenableOther SATCOMSCDU PromptsSecured,commonThis item determines if the disable other SATCOM andre--enable other SATCOM toggling SCDU prompts arepresented or suppressed. The SCDU prompts are usuallysuppressed if the optional external manual switch (thatcontrols the dual system select and disable discretes) issupplied so there is only one means of performing anyfunction at a time and the possibility of inadvertently disablingboth systems is avoided.li SCDU SATCOMSubsystemPromptsSecured,duplicatedThis item defines up to six ISO--5 characters used for theSCDU main menu SATCOM subsystem selection LSKprompts. The owner/operator is able to select any ISO--5characters and any length up to six characters. Examplecharacter strings would be SAT L and SAT R, or <SDU--1 and<SDU--2.](https://usermanual.wiki/Honeywell/HS-720.HS-720-User-Manual-Part3/User-Guide-1350372-Page-48.png)

ORT Characteristics (cont)ORT Item DescriptionAttributesCharacteristiclx AERO H OnlyOperationSecured,commonThis item defines the service mode when an HGA is installed.lxi HSD PreemptionPreferencesuser,commonThis ORT item defines the preferences to be used indetermining which channel(s)/call(s) will be preemptedwhen one or more HSD channels are among thepreemption candidates. The following preference sets areselectable:Level Retention Preferences0 C--P4 > MPDS/BGAN > ISDN1 C--P4 > ISDN > MPDS/BGAN2 MPDS/BGAN > C--P4 > ISDN3 MPDS/BGAN > ISDN > C--P44ISDN>C--P4>MPDS/BGAN5 ISDN > MPDS/BGAN > C--P4Ixii Ongoing HSDCall EIRPuser,commonThis item defines the minimum level of power that theSDU reserves for an ongoing Swift64 M--ISDN HSDcall. If the HSU requested EIRP falls below thisreserved EIRP level, then power reserved for the HSUwill freeze at this level even though the actual powerwill track the EIRP requested by the HSU. The definedrange of this item is 0.0 to 25.0 dBW.Ixiii WSC ManualDialinguser,commonThis item defines parameter options to be passed toany connected and active Williamsburg SDUcontroller(s) (WSCs), for the WSC’s own optionalusage. It has no other direct functionality within theSDU. It shall be capable of taking on the values“Disabled” and “Enabled”, and for the latter case, itspecifies the priority level (1 through 4, [for ManualDial Enable and Priority for Manual Dial] ) to be usedfor such calls.Ixiv Minimum HSDCall EIRPuser,commonThis item defines the minimum permissible level ofpower that the SDU deems adequate for an ongoingSwift64 M--ISDN HSD call. If the HSU requested EIRPfalls below this level, then the SDU terminates thecall. The defined range of this item is 0.0 to 30.0dBW.Ixv HSD RegistrationPreferenceuser,commonThis item specifies the type of HSD service(Swift64 or BGAN) which the HSU shall provide by way of thechosen satellite when in a region of both Swift64 andBGAN service coverage. The item defines theregistration preference to be eithera) automatic (i.e. BGAN when in BGAN coverage,otherwise Swift64 if in Swift64 coverage)b) Swift64 onlyc) BGAN only.](https://usermanual.wiki/Honeywell/HS-720.HS-720-User-Manual-Part3/User-Guide-1350372-Page-50.png)
