Configuring Upstream Channels

Upstream channels are used to transfer data from subscriber cable modems

to the headend site. Data transfer is accomplished in bursts. The Cu da

12000 supports four upstream channels per DOCSIS/EuroDOCSIS module.

Displaying Upstream Configuration and Statistics

You can display configuration and statistics for DOCSIS/EuroDOCSIS

upstream channels, including signal quality information. To do so, perform

the following tasks:

Task Command
1. Enter this command from root
mode or cable interface mode to
display parameters and statistics
for all upstream channels on the
specified cable interface.
show interface cable <c/s/i>
upstream
2. Enter this command from within
cable interface mode to display
parameters and statistics for all
upstream channels on the current
cable interface.
show upstream
3. Enter this command from within
root mode or cable interface
mode to display parameters and
statistics for a specific upstream
channel on the specified cable
interface. Channel IDs range from
1 to 4 (for 1x4 modules) or from 1
to 6 (for 1x6 modules).
show interface cable <c/s/i>
upstream <port number>
