Valid frequencies use the followingformat, with XXX representing a number from 91 to 869.• XXX.000• XXX.25• XXX.75Provides an unmodulated RF carrierNote: Continuous wave mode may be selected for eachcarrier.Disables the RF output. May be selected for each carrier.Prevents the DNCS from setting up any additionalsessions on this RF output if the DNCS is choosing QAMresources. Existing sessions are not affected and continueto function as expected. May be selected for each RFoutput.Allows you to select the Interleave setting based on thetype of set-top you are using on your system. Interleavingis a technique to overcome correlated channel noise.Interleaving spreads out bursts of errors to remain withinthe error-correcting ability of a device.Allows you to define which hubs will receive program orservice data from the RF output carrier78-745431-01 Rev E 41
