DSL Statistics
G.INP RTX_UC is a counter that is increased each time a frame is
detected in error and has not been corrected by one or more
retransmissions within the maximum delay period. The Local
number is received by the CPE, the Remote value received by the
DSLAM.
Note: The RTX_TX may not equal RTX_C + RTX_UC because of the infrequent
reboot nature of the DSLAM and the double-counting that the RTX_TX
counter might do.
Vector Error Samples Sent is the total number the CPE has sent to the
DSLAM during the test. A high number can indicate a network that is
unstable (CPEs joining / leaving, causing the VCE to continuously
recalculate the best solution).
Vector Error Samples Discardedis the total number of error samples
discarded. A high number can indicate a network that is unstable
(CPEs joining / leaving, causing the VCE to continuously recalculate the
best solution).
