Configuration Examples

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:

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	Assigns upstream port 0 to subchannel 4 using
modulation-profile 7	modulation profile 7, which must be a 1.5-MHz
	modulation profile.

Router(config-if)#radio upstream 1 subchannel 5	Assigns upstream 1 to subchannel 5, using
modulation-profile 7	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.

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
