DSL RTX
Table 12 describes the RTX (DSL Retransmission) results.
Signal
This category provides statistics for the signal. Table 12 describes the DSL Summary results.
UAS Unavailable Seconds. A count of the number of test seconds which met the ITU-T
Rec. G.821 definition of unavailable time.
LOS Loss of Signal. Number of errored seconds due to loss of signal.
LOF Loss of Frame. Number of errored seconds due to loss of framing.
LOM Loss of Margin Errors. Number of errored seconds due to loss of margin.
Table 12 DSL RTX results
Result Description
Status The state of modem synchronization
RTX-TX The number of retransmitted DTUs that were received.
RTX-C The number of DTUs we received a correction for
RTX-UC The number of DTUs that did not get a retransmission in time.
INP Rein The effective INP that G.INP support is giving us.
Table 13 DSL Signal results
Result Description
Sync Count The number of synchronization attempts. it is possible that modems do not
synchronize immediately and make multiple attempts before achieving syn-
chronization.
Uptime Amount of time the modems have been synchronized.
Path
RJ45
, (T/R or A/B)
SATN Signal attenuation. Attenuation average of the bins/tones that contain the
actual signal (empty bins are not included).
LATN Line attenuation. Attenuation average of all tones/bins (the entire line, includ-
ing empty bins/tones).
Tx Power Power level, in dB, of the VDSL signal, downstream (from the DSLAM) and
upstream (transmitted by the OneExpert DSL OneExpert DSL).
INTLV Delay Interleaving depth set by the DSLAM. This is a measure of latency introduced
on the link due to the scrambling of DSL frames to protect data and create a
more reliable link.
Actual INP The INP (Impulse Noise Protection) values negotiated during training.
