Chapter 7 System Status and Port Statistics Table 7 Status: VDSL Port Details (continued) LABEL DESCRIPTION LOFs UAS Code Violation Corrected Uncorrected Rtx RtxCorrected RtxUncorrected LEFTRs MinEFTR ErrFreeBits LOLs/LOL LPRs/LPR Time Elapsed VDSL Performance History This field displays the count of 1-second intervals containing one or more Loss of Framing (LOF) failures. This field displays the count of 1-second intervals for which the line is unavailable. Use this to define this line tolerance to allow how long for a period of Unavailable Seconds (UAS). Refer to ITU-T G997.1 chapter 7.2.1.1.5 for more detailed information. This field displays the number of code words containing one or more anomalies. This field displays the number of code words containing one or more error blocks that have been corrected. This field displays the number of code words containing one or more error blocks that can not be corrected. This field displays the number of RS (Reed-Solomon) codewords or DTUs (Data Transfer Units) retransmitted through PhyR or G.INP retransmissions. This field displays the number of RS codewords or DTUs that have been corrected through PhyR or G.INP retransmissions. This field displays the number of RS codewords or DTUs that were not corrected successfully through PhyR or G.INP retransmissions. This field displays the number of seconds during which the Error Free Throughput went below the pre-configured threshold. This field displays the lowest value of the Error Free Throughput within the current interval. This field displays the number of bits that passed through the alpha1/beta1 interface (bits that are available to carry user payload). This field displays the count of 1-second intervals containing one or more Loss Of Link (LOL) failures and the number of times an LOL failure occurred. This field displays the count of 1-second intervals containing one or more PoweR (LPR) failures and the number of times an LPR failure occurred. This field displays how many seconds has elapsed currently in this 15-minute (900 seconds) time segment. The counter restarts to zero after entering the next time segment. Click the 15 Min Interval link to display a screen listing VDSL performance information for the previous 15-minute periods. VDSL INM Performance History Click the One Day Interval link to display a screen listing VDSL performance information for the previous 24-hour periods. Click the Current link to display a screen listing INM (Impulse Noise Monitor) counters recorded since the link was last up or counters for the current 15-minute and 24-hour periods. Click the 15 Min Interval link to display a screen listing INM counters for the previous 15-minute periods. Click the One Day Interval link to display a screen listing INM counters for the previous 24-hour periods. VDSL sub-carrier status See Section 9.3.9 on page 121 on how to configure VDSL INM profiles which define INM control parameters. This section allows you to select the criteria below and display you the status in a raw data list or in a graph. 64 VES1724-56 User's Guide
