cable upstream frequency
The following example shows how to configure the upstream center frequency to a frequency
(54,700,000 Hz) within the extended Japanese frequency range:
Router# configure terminal
Router(config)# upstream freq-range japanese
Router(config)# interface cable 3/0
Router(config-if)# cable upstream 0 frequency 54000000
Router(config-if)# exit
Router(config)# exit
Router#
The following example shows how to allow the Cisco CMTS to dynamically specify a center frequency
for the upstream port 0:
Router(config-if)# no cable upstream 0 frequency
The following command example from Cisco IOS Release 12.3 BC illustrates the allowable upstream
frequency range in Hz:
Router(config-if)# cable upstream 3 frequency ?
<5000000-55000000> Upstream Frequency in Hz
