Port |
The port assigned to this interface. |
Rate Mode |
Specifies the rate selection behavior for the line in the upstream direction. manual: forces the rate to the configured rate adapt-at-init: adapts the line at initialization only dynamic: adapts the line at initialization and showtime Default: dynamic |
Maximum Power(dB) |
Specifies the maximum aggregate upstream power level in the range 0 to 14.5 dBm (in 0.1dBm). Default: 145 |
Maximum SNR Margin(dB) |
Specifies the maximum upstream Signal/Noise Margin in units of 0.10 dB, for a range of 0 to 31.0 (in 0.1dBm). Default: 160 |
Minimum SNR Margin(dB) |
Specifies the minimum upstream Signal/Noise Margin in units of 0.10 dB, for a range of 0 to 31.0 dB (in 0.1dBm). Default: 0 |
Target SNR Margin(dB) |
Specifies the target upstream Signal/Noise Margin in units of 0.10 dB, for a range of 0 to 31.0 dB. This is the Noise Margin the transceivers must achieve with a BER of 10^-7 or better to successfully complete initialization. Default: 60 |
Fast Maximum Data Rate(KB/s) |
Specifies the maximum upstream fast channel data rate in steps of 1000 bits/second. The maximum aggregate upstream transmit speed of the line can be derived from the sum of maximum upstream fast and slow channel data rates. Default: 60,000 |
Fast Minimum Data Rate(KB/s) |
Specifies the minimum upstream fast channel data rate in steps of 1000 bits/second. The minimum aggregate upstream transmit speed of the line can be derived from the sum of minimum upstream fast and slow channel data rates. Default: 0 |
Interleave Maximum Data Rate(KB/s) |
Specifies the maximum upstream interleave channel data rate in steps of 1000 bits/second. Default: 60,000 |
Interleave Minimum Data Rate(KB/s) |
Specifies the minimum upstream interleave channel data rate in steps of 1000 bits/second. Default: 0 |
Power Backoff Control |
Upstream power backoff (PBO) control for this line. For transceivers which do not support upstream PBO control, this object MUST be fixed at disabled. If auto is selected, the transceiver will automatically adjust the power backoff. If manual is selected, then the transceiver will use the value from PBO Level. disabled auto manual Default: Disabled |
PBO PSD Template |
The upstream PSD template to be used for the line. Default: ansi-fftcab-m1 |
Downshift SNR Margin |
Configured Signal/Noise Margin for rate downshift. If the noise margin falls below this level, the modem should attempt to decrease its transmit rate. Default: 30 |
Upshift SNR Margin |
Configured Signal/Noise Margin for rate upshift. If the noise margin rises above this level, the modem should attempt to increase its transmit rate. Default: 90 |
Min Downshift Time |
Minimum time (in seconds) in seconds that the current margin is below downshiftSnrMgn before a downshift occurs. Default: 30 |
Min Upshift Time |
Minimum time (in seconds) in seconds that the current margin is above upshiftSnrMgn before an upshift occurs. Default: 30 |
Bit Swap |
Enable or disable downstream bit swap. Default: enabled |
Impulse Noise Protection |
The minimum impulse noise protection for the upstream bearer channel expressed in symbols. One symbol equals 250 uS. noProtection, halfSymbol, singleSymbol, twoSymbols, fourSymbols, eightSymbols, sixteenSymbols Default: twoSymbols |
Max Interleaving Delay |
Specifies the maximum interleave delay for the downstream slow channel. Default: 20 |
PhyR Support |
Enable or disable downstream PHYR. enable disable Default: enable |
PhyR Max INP |
PHYR maximum upstream impulse noise protection. A value of 0 specifies no protection. The values 5 through 160 specify the number of symbols in 1/10 increments. Default: 0 |
PhyR Min RSOverhead |
PHYR minimum downstream RS overhead. Default: 0 |
PhyR Rtx Ratio |
PHYR minimum downstream fraction of the line rate allocated for retransmission. Default: 0 |
