"Deploying Lucent's new high-capacity
tandem switch increases our efficiency and simplifies our network by avoiding the operations and maintenance costs, and complexity of adding multiple smaller switches," said Andre Fuetsch, SBC Vice President-Network Planning.
A
tandem switch is an intermediate switch that interconnects end-office switches with the toll network, which carries long-distance calls.
Switching technology has changed so much that we can serve much more efficiently with one or two or three switches in a serving area than we could with the traditional telephone architecture, where you have a
tandem switch and many end offices.

tandem switch are shown in Figure 3.
