Ranging Not Complete - Cisco DPC2203C Installation And Operation Manual

Ranging Not Complete

Description
After the cable modem finds the CMTS downstream channel and upstream
parameters, it starts the ranging and automatic adjustments stage. This stage adjusts
the timing offset and the power level for communication with the CMTS.
Note: For more information on this process, see Adjust Timing Offset and Power
Level (on page 9).
The following table illustrates the status of the front-panel LED status indicators
when the ranging not complete condition exists.

channel of the CMTS.
