Burst Profile Configuration
For each modulation/burst profile configuration, Cisco uBR7200 series universal broadband routers
support burst profile number, burst profile interval usage code, burst type, preamble length and unique
word length, differential encoding enable/disable, forward error correction (FEC) correctable bytes
value, FEC code word length, scrambler seed value, maximum burst size, guard time size, last code word
shortened/lengthened, and scrambler enable/disable.
Multiple burst profiles are supported on the MC11C, MC12C, MC14C, MC16B, and MC16C cable
Note
modem cards. Only one profile is supported on the original MC11-FPGA card.
Cable Modulation Profile Default Templates
Commencing with Release 12.1(3a)EC1 and later releases, the cable modulation-profile global
configuration command has been enhanced with three new options that enable you to quickly create
basic modulation profiles using the default values for each burst type.
To define the modulation profile, use the cable modulation-profile command in global configuration
mode. Use the no form of this command to remove the entire modulation profile or to reset a particular
burst to its default values.
