Multipoint Wireless Support for the Cisco uBR7200 Series Universal Broadband Router

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:

one "channel"

1

23

4

5

6

7

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
