Splitting an upstream channel
The following steps show how to split an upstream channel into two smaller upstream channels. In this
example, a 3-MHz upstream (upstream 0, subchannel 2) is split into two 1.5-MHz upstreams, using the
following commands. Refer to the following subchannel map as a reference for the subchannel
assignments:
Modulation Profiles Configurations
The following are examples of modulation profiles:
radio modulation-profile 1 bandwidth 3.0 throughput 6.6 multipath-robustness high
burst-length medium
radio modulation-profile 2 bandwidth 3.0 throughput 8.6 multipath-robustness high
burst-length medium
radio modulation-profile 3 bandwidth 3.0 throughput 4.4 multipath-robustness high
burst-length medium
Command Purpose
Router(config-if)# no radio upstream 0 subchannel
Removes the subchannel assignment from
upstream port 0.
Router(config-if)# radio upstream 0 subchannel 4
modulation-profile 7
Assigns upstream port 0 to subchannel 4 using
modulation profile 7, which must be a 1.5-MHz
modulation profile.
Router(config-if)# radio upstream 1 subchannel 5
modulation-profile 7
Assigns upstream 1 to subchannel 5, using
modulation profile 7.
Router(config-if)# no radio upstream 0 shutdown
Enables upstream 0.
Router(config-if)# no radio upstream 1 shutdown
Enables upstream 1.
