Advanced Status

The clear button will only reset Training Time. The rest of the counters are stored in the Alcatel chip set and can only be cleared by Resetting the modem.

Field

Meaning

Training Time

The time it took, or is taking, in seconds for your modem to connect or "train" to the ADSL line.

Loss of Signal

A count of the number of times the modem lost synchronization with the ADSL line. This value can be non zero as it is normal for the modem to occasionally lose synchronization. If this value is consistently counting upwards and the modem is having problems connecting it could be caused by one of the following reasons:

1. The modem is not using the same wire pair as the ADSL line is on. All RJ-11 jacks are 4 wire pairs. The modem expects to see the signal on the inner wire pair.

2. The modem (if it's an internal one) may be picking up unacceptable noise from the power supply or some other source on the PC. You can try moving the modem into a slot as far away from the PCs power supply as possible.

3. The ADSL line may not be active or may be "down" from the Service Provider. Will need to check with them to validate.

CRC

The number of CRC errors received by the modem.

HEC

This is the same count as HEC errors on the ATM/AAL5 screen.

FEC

The number of "Forward Error Correction" errors received by the modem. This count only increments when using Interleaved vs. Fast Path mode with the DSLAM. These are errors that could be corrected through Forward Error Correction.

Line Rate Upstream

The speed at which the modem connected in the upstream (transmit) direction.

Line Attenuation Upstream The Upstream Attenuation refers to the measured power difference in the power transmitted by the modem and the power received by the remote end transceiver.
SNR Margin Upstream This is the Signal to Noise Ratio, expressed as a margin, for the Upstream (transmit) direction. You should never see a negative noise margin with a good connection. If you do, you need to have the modem re-train. This done by using the Reset button or re-starting the computer.
Output Power Upstream This value, shown in decibels, is the calculated transmitted power of the modem. The modem starts up initially with default transmit power setting of 0 dB. This ensures that the highest amount of power will be applied. The service provider can attenuate this value by sending messages to the modem to lower transmit power levels. The power level can be controlled from the DSLAM. There is no magic number here, but the higher it is the better the connection. Somewhere between 4 and 12 is good. Factors that will effect power are the distance from the DSLAM.
Line Rate Downstream The speed at which the modem connected in the downstream or (receive) direction.
Line Attenuation Downstream The Downstream Attenuation on the ADSL signal refers to the measured power difference in the total power transmitted by the remote end transceiver and the power received by the modem. The network operator can adjust the amount of attenuation to control the transmit power.
SNR Margin Downstream This is the Signal to Noise Ratio, expressed as a margin, for the Downstream (receive) direction. You should never see a negative noise margin with a good connection. If you do, you need to have the modem re-train. This done by using the Reset button or re-starting the computer.
Output Power Downstream This value, shown in decibels, is the calculated receive power of the modem. The modem starts up initially with default receive power setting of 0 dB. This ensures that the highest amount of power will be applied. The service provider can attenuate this value by sending messages to the modem to lower receive power levels. The power level can be controlled from the DSLAM. There is no magic number here, but the higher it is the better the connection. Somewhere between 4 and 12 is good. Factors that will effect power are the distance from the DSLAM.
