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 indicatin
g
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 noted. This means that when the
modem is disconnected, these values should immediately
report zero.
Connection Status
The Connection Status field chan
g
es 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
