|
Field | Meaning |
|
|
Down Alarms | Identifies the current alarms in the path to the subscriber. |
|
|
Up Alarms | Identifies the current alarms in the path from the subscriber. |
|
|
System State | Describes the state of the ADSL system. |
| Startup states: |
| DATA (normal operation) |
| HAND (handshake) |
| TRAIN (training transceivers for loop conditions) |
| WSYNC (waiting for frame synchronization) |
|
|
SNR Margin (dB) | Identifies the current (cur) and minimum (min) margin values |
| for the ADSL loop for the current |
| margin represents the margin relative to the SNR required for |
| a BER of |
| performance better than |
| margin of 6 dB, which translates to a performance of |
| BER or better. See page 2 for information on SNR margin |
| and BER. |
|
|
Line Attn (dB) | Indicates the decrease in amplitude of the transmitted |
| upstream and downstream signals as measured at the ADSL |
| respective receivers for that channel (upstream or |
| downstream). |
|
|
24 Hour ES | Indicates the total number of ES that have been detected on the |
| ADSL link during the previous |
|
|
24 Hour UAS | Indicates the total number of unavailable seconds (UAS) that |
| have been detected on the ADSL link during the previous |
| |
| the lines were not available for transmission since power on or |
| last clear. |
|
|
Data Rate (kbps) | Identifies the actual data rates of the ADSL link. |
