Shows the collected data of all error correction
The previous net data rate that the bearer channel was operating at just
before the latest rate change event. This could be a full or short
initialization, fast retrain, DRA or power management transitions, excluding
transitions between L0 state and L1 or L2 states. The data rate is coded in
bit/s.
Maximum Attainable Data Rate Upstream.
The maximum upstream net data rate currently attainable by the VTU-R
transmitter and the VTU-C receiver, coded in bit/s.
This parameter contains the estimated electrical length expressed in dB at
1 MHz, kl0. This is the final electrical length that would have been sent
from the VTU-O to VTU-R if the electrical length was not forced by the
CO-MIB.
The value ranges from 0 to 128 dB in steps of 0.1 dB.
SNR Margin is the maximum increase in dB of the noise power
received at the VTU (VTU-R for a band in the downstream direction and
VTU-C for a band in the upstream direction), such that the BER
requirements are met for all bearer channels received at the VTU. Values
range from -640 to 630 in units of 0.1 dB (Physical values are -64 to 63
dB). A special value of 0x7FFFFFFF (2147483647) indicates the SNR
Margin is out of range to be represented. A special value of 0x7FFFFFFE
(2147483646) indicates the SNR Margin measurement is currently
unavailable
Total elapsed seconds in this interval
Count of seconds during this interval that there was at least one FEC
correction event for one or more bearer channels in this line. This
parameter is inhibited during UAS or SES
Count of seconds during this interval that there was:
VTU-C: CRC-8 >= 1 for one or more bearer channels OR
LOS >= 1 OR SEF >=1 OR LPR >= 1
VTU-R: FEBE >= 1 for one or more bearer channels OR
