What is a possible consequence of not testing VDV circuits thoroughly?

Not testing VDV circuits thoroughly can indeed lead to higher costs in repairs and maintenance. When circuits are not properly tested, underlying issues may go unnoticed until they result in failures or degraded performance. This can lead to unexpected outages, requiring technicians to perform emergency repairs, which are often more costly than planned maintenance. Additionally, not identifying and fixing problems during the testing phase can worsen over time, compounding issues and ultimately leading to more extensive repairs that are more expensive and time-consuming.

Thorough testing helps to ensure that circuits are functioning correctly and meet performance standards, which can help mitigate future repair needs and costs. By spending adequate time in the testing phase, potential problems can be addressed early, reducing the risk of incurring higher maintenance expenses later on.
