What is a consequence of losing a tandem switch?

Losing a tandem switch has a direct impact on call routing and Automatic Number Identification (ANI) services. A tandem switch is a crucial component in a telephone network, serving as an intermediary between different local exchanges. When it is operational, it facilitates the efficient routing of calls between these exchanges, ensuring that calls are directed to the correct destination.

In the event of its loss, the network may struggle to manage call traffic effectively, leading to disruptions in call routing. This means calls may not be connected correctly or at all, resulting in failure to reach the intended recipient. Moreover, without the tandem switch, ANI services—which are responsible for identifying a caller's number for billing and emergency services—would be compromised. This could hinder emergency response teams from locating individuals in distress, drastically affecting public safety and the overall effectiveness of telecommunications services.
