The throughput is displayed as line graphs that move from left to right
across the screen. The color-coded list of remote site names to the right
of the graphs correspond to the colored lines on the graph. A maximum
of four remote sites are monitored simultaneously. Performance is
measured in kilobytes per second (Kbps), with samples taken every five
seconds. The maximum throughput for all remote site connections
combined is determined by the service provider when the SDSL link
comes up. This maximum can be calculated from the negotiated SDSL
baud and constellation rates (see ATM Interface section below.)
Because the SDSL link is shared by all remote site connections, the
throughput for a specific connection varies depending on the traffic of
the other connections. If one connection is using most of the bandwidth,
there is less available for the other connections. Throughput also depends
on the type of traffic on the connection. For example, downloading a text
file from the Internet may generate a very low volume of incoming traffic,
while receiving high resolution graphics display will cause the received
throughput to increase dramatically.
