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 Receive

The throughput is indicated through two bar graphs, each 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 10-second period. 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 10-second period. This value is 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 non-averaged operational information are reported as zero unless otherwise CSA User Screen Connection Status noted. This means that when the modem is dis- connected, these values should immediately report zero.

Connection Status

The Connection Status field changes to indicate the status of the modem connec-
