ADSL Statistical Parameter

Description

 

 

Operational State

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 (dB)

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.

DSP Version

The modem DSP code can be upgraded—this is the

 

current version that is running on your system.

Last Failed

Shows the last state reached before start-up failed. This is

 

used for troubleshooting by technicians.

Local Attenuation (dB

Current power attenuation at the modem.

Remote Attenuation (dB)

Current remote power attenuation.

Local SNR Margin (dB)

Current Signal to Noise (SNA) ratio.

Local Tx Power (dB)

Current transmit power attenuation at the modem.

Remote Tx Power (dB)

Current remote transmit power attenuation.

RS Frame Count

Reed Solomon frame count of forward error corrections on

 

the DSL line.

Downstream Data Rate

Actual downstream data bit rate after ATM headers have

 

been removed.

Upstream Data Rate

Actual upstream data bit rate after ATM headers have been

 

removed.

Total Failure Count

Total count of errors including CRC, loss of signal, and

 

framing errors.
