Telecom Model 2: Performance Issues

The telecom example shown in Figure 5.2 might be used to investigate performance issues between several locations. The section of the model between the two Toll Digital Switch models might represent an interexchange carrier segment. Using this model, you could investigate the impact of using different interexchange carriers or possibly examine the effects of replacing various pieces of equipment in the network on different performance attributes (for example, noise and delay). If you replace the local and tandem switch models with their PBX counterparts, this model could represent a small corporate network.
