configure interface cable-upstream * cable power-level
Provisions the power level for an upstream.
configure interface cable-upstream <slot/ch[.0]> cable power-level <int>
The C4 CMTS ships with receive power levels set to a default of 11 dBmV. This level may prove unsuitable for a given cable plant. If,
for example, the loss on a given node were so great that the CMs could not transmit a strong enough signal to reach the C4 CMTS at
11 dBmV, then you would want to lower the expected receive power. If desired, change the input receive power to any level from -
16 to 29 dBmV according to the upstream bandwidth.
If the channel width is changed and the receive power level is no longer valid, the C4 CMTS automatically adjusts the receive power
to the nearest valid value.
Parameters
The upstream slot/channel[.logical channel]. It will assume lc=0 if needed and not supplied.
Power level (dbmV). Range is dependent on channel width.
