DESCRIPTION
This displays the upstream coding mode. 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 displays the downstream coding mode. 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 number of milliseconds of interleave delay for upstream transmissions.
This is the number of milliseconds of interleave delay for downstream transmissions.
This is the number of impulse noise protection DMT symbols for upstream transmissions.
This is the number of impulse noise protection DMT symbols for downstream
transmissions.
This is the power output of the subscriber's DSL modem or router. The total output power
of the transceiver varies with the line length and quality.
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.
This field displays the configured upstream and downstream rates on the SHDSL 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.
