The following table describes the labels in this screen.
Table 41 VDSL Channel Profile Setup > G.INP
LABEL DESCRIPTION
DownStream The parameters in this column relate to downstream transmissions.
Upstream The parameters in this column relate to upstream transmissions.
G.INP Mode Select G.INP retransmission mode.
Forbidden: G.INP is disabled on the Switch.
Preferred: G.INP is enabled if the far-end (CPE device) supports it.
Forced: The VDSL connection can be established only if the far-end supports G.INP mode.
Test: G.INP is enabled only in test mode.
Effective
Throughput
Specify the maximum and minimum value allowed for the ETR (Effective Throughput
Rate).
Net Data
Rate(NDR)
Specify the maximum downstream/upstream net data rate.
Shine Ratio Specifies the loss of data rate you predict to occur within 1 second due to SHINEs (Single
high impulse noise events).
The valid values are all multiples of 0.001 and between 0 and 0.1.
LEFTR Threshold Specify the lower rate limit (fraction of NDR). A Low Error Free Rate (LEFTR) defect is
declared when the rate falls below the threshold.
Max Delay Specify the maximum delay (from 1 to 63 in ms) that is added to the retransmission delay
caused by retransmissions.
Min Delay Specify the minimum delay (from 0 to 63 in ms) that is added to the retransmission delay
caused by retransmissions.
Min INP Specify the minimum level of impulse noise (burst) protection.
