Which act exemplifies deliberately causing telecommunications service interruptions?

The act of repeatedly calling without speaking directly exemplifies deliberately causing telecommunications service interruptions. This behavior could overwhelm telecommunications networks by generating unnecessary call traffic, leading to service disruptions for both the caller and other users. Such actions can be viewed as frivolous or malicious, as they serve no legitimate purpose and can impede the ability of emergency services and other critical communications from functioning properly.

In contrast, making necessary emergency calls is a legitimate use of telecommunications services and is crucial for public safety. Exchanging business information is a productive form of communication that can enhance operations rather than disrupt them. Arranging social gatherings also represents a normal social interaction that does not interfere with telecommunications services. Thus, the only option that reflects intentional disruption of telecommunications functionality is the repeated calling without speaking.
