2. To view a specific modulation profile, use the show cable modulation-profile
command in Privilege EXEC mode, as shown below:
MOT#show cable modulation-profile {<1-16>}
where:
1-16 is the profile group number.
3. To create a modulation profile that contains the initial ranging burst parameters,
use the cable modulation-profile command in Global Configuration mode, as
shown below:
MOT(config)#cable modulation-profile {<1-16>} [initial <0-10> | long
<0-10> | request <0-10> | short <0-10> | station <0-10>] {<16-23>} {<0-255>}
16qam [scrambler | no scrambler] qpsk [scrambler <0x0-0x7fff> | no
scrambler <0x0-0x7fff>] [diff | no-diff] <64-256> [fixed | shortened]
Table 6-5 provides a description of each parameter listed in the cable
modulation-profile command syntax above and what value that needs to be
entered for each parameter:
Table 6-5 Modulation Profile Parameters and Descriptions
Parameter Description
1-16 Profile group number.
initial <0-10> Interval Usage Code (IUC) for intial ranging burst.
long <0-10> IUC for long grant burst.
request <0-10> IUC for request burst.
short <0-10> IUC for short grant burst.
station <0-10> IUC for station ranging burst.
16-253 FEC code word length.
0-255 Maximum burst length in minislots. 0 means no limit.
16qam [scrambler
<0x0-0x7fff> | no
scrambler]
Modulation type. If enabling the scramber option identify the
scrambler seed in hexidecimal format.
qpsk [scrambler | no
scrambler]
Modulation type. Enable or disable the scramber option identify
the scrambler seed in hexidecimal format.
diff Enable differential encoding.
no-diff Disable differential encoding.
