DESCRIPTION
Click Flush to clear the counters.
This displays the connection status of the DSL link.
This is the DSL standard that the port is using.
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.
