11-2CHAPTER 11: MONITORING THE OFFICECONNECT REMOTE 840

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.
