ITUB Interleave Screen

The ITUB Interleave screen displays the interleave depth factor for all ITU-B

evenly disperses the data to transport it reliably over the cable channel.
Important: The recommended setting for this screen is 128,4. Only Cisco Services
representatives should modify this setting.
