Field Name Description
l Accounting for the loop characteristics at the instant of measurement [2]
PhyR Status Physical Layer Retransmission feature status. Options are
Inactive
and
Active
.
G.inp Status The status of video data retrieval from the buffer. Options are
Inactive
and
Active
.
Rate (Kbps) The current net data rate of the xDSL link. Net data rate is defined as the sum of all frame
bearer data rates over all latency paths. [2]
Downstream
and
Upstream
columns for DSL-specific fields only
B (# of bytes in Mux
Data Frame)
The nominal number of bytes from frame bearer #n per Mux Data Frame at Reference Point A
in the current latency path.
M (# of Mux Data
Frames in FEC Data
Frame
The number of Mux Data Frames per FEC Data Frame in the current latency path.
T (Mux Data Frames
over sync bytes)
The ratio of the number of Mux Data Frames to the number of sync bytes in the current
latency path.
R (# of check bytes
in FEC Data Frame)
The number of Reed Solomon redundancy bytes per codeword in the current latency path.
This is also the number of redundancy bytes per FEC Data Frame in the current latency path.
S (ratio of FEC over
PMD Data Frame
length)
The ratio of FEC over PMD Data Frame length.
L (# of bits in PMD
Data Frame)
The number of bits from the latency path included per PMD.
D (interleaver
depth)
The interleaving depth in the current latency path, used to manager error correction.
I (interleaver block
size in bytes)
The block sizeused for interleaving data transmissions.
N (RS codeword
size)
The size of the Reed-Solomon (RS) codeword used for managing error correction.
Delay (msec) The PMS-TC delay in milliseconds of the current latency path (or the lowest latency path
when running dual-latency paths).
INP (DMT symbol) The input level for DMT-managed DSL environments.
(End of DSL-specific field group)
OH Frames The number of xDSL OH Frames transmitted/received.
OH Frame Errors The number of xDSL OH Frames transmitted/received with errors.
RS Words The number of Reed-Solomon-based Forward Error Correction (FEC) codewords trans-
mitted/received.
RS Correctable
Errors
The number of Reed-Solomon-based FEC codewords received with errors that have been cor-
rected.
RS Uncorrectable
Errors
The number of Reed-Solomon-based FEC codewords received with errors that were not cor-
rectable.
RS Codewords
Received
(
Visible only for gateways connected via DSL
) Total number of Reed-Solomon Codewords
received.
RS Codewords Cor-
rected
(
Visible only for gateways connected via DSL
) Total number of Reed-Solomon Codewords cor-
rected.
