DESCRIPTION
This displays the connection status of the DSL link.
This is the DSL standard that the port is using.
Trellis coding helps to reduce the noise in ADSL transmissions. Trellis may reduce
throughput but it makes the connection more stable.
"RS" coding stands for Reed-Solomon error correction.
This is the numbers of milliseconds of interleave delay for upstream
transmissions.
This is the numbers of milliseconds of interleave delay for downstream
transmissions.
This is the DSP port's output power. The total output power of the transceiver
varies with the length and line quality. The farther away the subscriber's ADSL
modem or router is or the more interference there is on the line, the higher the
power will be.
This is the country code acquired from the subscriber's ADSL device during
negotiation/provisioning message interchanges. The country code is from the
Vendor ID (see ITU-T G.994.1).
This is the provider code acquired from the subscriber's ADSL device during
negotiation/provisioning message interchanges. The provider code includes the
Vendor ID and Version Number obtained from the Vendor ID.
This is the minimum upstream and downstream rates on the SHDSL port.
port.
This field displays the actual upstream and downstream rates on the SHDSL port.
These are the SHDSL line's noise margins. Measured in decibels (dB).
These are the reductions in amplitude of the SHDSL signals. Measured in
decibels (dB).
This is the number of Linkup attempts on the VDSL port.
This field displays the name of the CO VDSL device vendor.
This field displays the name of the CO VDSL device hardware version.
This field displays the name of the CO VDSL device serial number.
This field displays the name of the CPE VDSL device vendor.
This field displays the name of the CPE VDSL device hardware version.
This field displays the name of the CPE VDSL device serial number.
This is the number of far end cyclic redundancy checks.
This is the number of near end cyclic redundancy checks.
This is the number of far end corrected blocks.
The is the number of near end corrected blocks.
This is the number of Errored Seconds. This is how many seconds contained at
least one errored block or at least one defect.
This is the number of Severely Errored Seconds. This is how many seconds
contained 30% or more errored blocks or at least one defect. This is a subset of
Es.
This is the number of Unavailable seconds (Uas).
