| Modem Performance | The Modem Performance displays performance |
| |
|
| information. The primary purpose is to display the |
| |
|
| instantaneous throughput rate for both transmit and |
| |
|
| receive paths of the modem. This rate is calculated based |
| |
|
| on the poll period (generally 2 seconds) and the number |
| |
|
| of bytes passed during that time. |
| |
| TRANSMIT AND | The throughput is indicated through two bar graphs, each |
| |
| RECEIVE | provides a maximum rate label indicating the transmit and |
| |
|
| receive bit rates currently in use. The bar graph displays |
| |
|
| peak throughput rates over the last |
| |
|
| Basically, the user interface records the instantaneous |
| |
|
| throughput for each poll period over the last 10 seconds, |
| |
|
| and the peak rate is displayed as the maximum value |
| |
|
| achieved over that |
| |
|
| indicated on the throughput graph with a vertical red |
| |
|
| marker indicating the peak rate. |
| |
|
| The user interface displays operational information about |
| |
|
| the ADSL modem, relevant when the modem is |
| |
|
| connected. When the modem is not connected, all of the |
| |
|
|
| ||
|
| zero unless otherwise noted. This means that when the |
| |
|
| modem is disconnected, these values should immediately |
| |
|
| report zero. |
| |
| Connection Status | The Connection Status field changes to indicate the status |
| |
|
| of the modem connection: |
| |
|
| • | ADSL link connected |
|
|
| • | ADSL link disconnected |
|
| Device Status | The Device Status field changes to indicate the status of |
| |
|
| the modem connection: |
| |
|
| • | ADSL Modem available |
