show adsl statistics Displays block count statistics for the ADSL interface. It reports the number of
blocks transmitted and received. It also reports the number of blocks received with
corrected errors, and the number received with uncorrectable errors.
show adsl
transceiver_status
Displays the current status of the ADSL transceiver. It lists:
■
Operational Mode – Current operational mode of the transceiver.
■
Attenuation – the difference in dB between transmitted and received signal
power.
■
Signal to Noise Ratio Margin – the SNR margin required by the transceiver
to maintain the ADSL link.
■
Transmit Power - The transmit power in dB of the local ADSL transceiver.
■
Code Word Length – The current code word size for the fast interlayed paths.
■
Downstream Rate – the negotiated bit rate for data received from the
network.
■
Upstream Rate – the negotiated bit rate for data transmitted to the network.
show adsl version Displays version information about the ADSL interface. It lists:
■
Hardware Release Version - Version of the ADSL chipset present on the unit.
■
Firmware Release Version - Version of the ADSL firmware present on the
unit.

■
RX No Pkt Avail - Number of times a packet was reassembled but could not
be delivered over the LAN because of lack of packet memory within the
HomeConnect ADSL Modem.
■
RX Bad VPI or VCI - Number of ATM cells received with a bad or inactive VPI
and/or VCI number.
