Description
Valid entries are:
• Handshaking—the transceiver is exchanging or
attempting to exchange information necessary to start
up.
• Training—the transceiver is in the process of starting
up.
• Show Time—the transceiver has started up, trained,
and is capable of passing user data.
Coding gain is the expected improvement or gain due to
trellis/RS coding. It is used to help determine the
downstream connection rate. The larger this value is, the
higher the connection rate will be.
The modem DSP code can be upgraded—this is the
current version that is running on your system.
Shows the last state reached before start-up failed. This is
used for troubleshooting by technicians.
Current power attenuation at the modem.
Current remote power attenuation.
Current Signal to Noise (SNA) ratio.
Current transmit power attenuation at the modem.
Current remote transmit power attenuation.
Reed Solomon frame count of forward error corrections on
the DSL line.
Actual downstream data bit rate after ATM headers have
been removed.
Actual upstream data bit rate after ATM headers have been
removed.
Total count of errors including CRC, loss of signal, and
framing errors.
