Thread: what do 'near end' and 'far end' indicators refer to?

Screenshot from the adsl status page of my modem,

What do these indicators mean?

4) Upstream / Near End Indicator
The number of transmit data frames from Client ADSL Modem to Central Office DSLAM.

5) Downstream / Far End Indicator
The number of transmit data frames from Central Office DSLAM to Client ADSL Modem.

6) Noise Margin
Amount of increased noise that can be tolerated while maintaining the designed BER(bit error rate). The Noise Margin is set by Central Office DSLAM. If the Noise Margin is increased, bit error rate performance will improve, but the data rate will decrease. Conversely, if the Noise Margin is decreased, bit error rate performance will decrease, but the data rate will increase.

7) Attenuation
Attenuation is the decrease in magnitude of the ADSL line signal between the transmitter (Central Office DSLAM) and the receiver (Client ADSL Modem), measured in dB. It is measured by calculating the difference in dB between the signal power level received at the Client ADSL modem and the reference signal power level transmitted from the Central Office DSLAM.

8) Loss of Signal Defect
This field displays the count of event of ADSL signal loss.

9) Fast Path CRC Error / Interleaved Path CRC Error
This field displays the number of transmit data frames containing CRC errors per second since training.

10) Fast Path FEC Correction / Interleaved Path FEC Correction
This field displays the FEC(Forward Error Correction) and indicates that errors were detected and corrected in the codeword.

11) Fast Path HEC Error / Interleaved Path HEC Error
This field displays the HEC(Header Error Control) and indicates that the mismatches in the header of ATM packets since start of link.

12) Received Cells
This field displays the number of cells received.

13) Transmitted Cells
This field displays the number of cells transmitted.

Thankyou very much

@Nick H

Thanks for the rep++ points. ( Info from Belkins site )
I have not checked these data till now, and usually SNR/ATTN gives
enough information.

User has no control over these extra data, and by just improving SNR and reducing ATTN locally or at the ISP end error data will be nil.

Worst case scenario change the modem !!!

Some users, trying to improve speed/ping time etc for games/torrents, want to know all these details.
