Moving A Cm Or Mta To A Different Upstream Channel; Adjusting For Physical Delay Between Cable Interface And Cms - Motorola BSR 2000 Configuration And Management Manual

Release 1.0

Moving a CM or MTA to a Different Upstream Channel

Use the cable modem ucc command in Privileged EXEC mode to move a CM/MTA
to a different upstream channel
A CM or MTA can be moved to a different upstream channel within the same
spectrum group and the same MAC domain after registration to balance the number of
CM/MTAs evenly among the receivers of the CMTS module to utilize the entire
upstream bandwidths more efficiently.

Adjusting for Physical Delay between Cable Interface and CMs

The physical delay function is used to adjust the upstream propagation delay
threshold between the cable interface and cable modems (CMs). The cable interface
adjusts the physical delay function automatically by default.
You can use the following options to adjust the physical delay function:
Use the cable upstream physical-delay automatic command in Interface
Configuration mode to set the automatic physical delay value for an upstream
channel:
MOT (config-if)# cable upstream <NUM> physical-delay automatic
[<10-1600> | <10-1600>]
where:
526360-001-00 Rev. B
mac is the cable modem MAC address
prefix is the cable modem IP address.
0-3 is the Channel number.
A single fixed time can be set for physical delay.
Physical delay parameters can be configured so that they are adjusted
automatically by the BSR when you specify the automatic option with a specified
minimum and maximum microsecond range.
If you do not want to specify a range for the automatic option, select the
automatic option only.
NUM is the upstream port number.
200-1600 is the minimum upstream physical delay in microseconds. The default
value is 200 microseconds.
