VDSL Port Link Status
Fields and Attributes
•
Link
–
Shows the status of the VDSL link.
•
Link Fail Count –
The number of times the switch has tried to
re-establish the link with the CPE since the link went down.
•
SNR
(dB)
–
The signal-to-noise ratio of the switch.
•
Downstream Rate (Mbps) –
The rate at which data is transmitted
from the switch to the CPE.
•
Upstream Rate (Mbps) –
The rate at which data is transmitted from
the CPE to the switch.
•
Local Receiver Power
(dBm/Hz)
–
The power at which the signal
from the CPE port is received on the switch VDSL port.
•
Remote Transmit Power
(dBm/Hz) – The power at which the signal
is transmitted from the CPE port to the switch.
•
PMD-S –
Physical Media Dependent Flag for the VDSL chip.
•
Downstream Reed-Solomon Errors –
The number of errors in the
downstream data that have been corrected by the Reed-Solomon code.
•
Upstream Reed-Solomon Errors –
The number of errors in the
upstream data that have been corrected by the Reed-Solomon code.
•
Local/Remote Receive Interleave Depth –
The interleave depth is
a parameter that determines the degree of protection of the data signal
against impulse noise provided by interleaving. The values of the
interleave depth that can be set by the user are 0, 1, 2, 8, and 16; 16
specifies maximum protection. Local Receive Interleave Depth refers
to protection provided on the signal received at on the VDSL switch
port. Remote Receive Interleave Depth refers to protection provided
on the signal received on the CPE port.
