Introduction
Telecom site administration depends on a practical grasp of how systems and networks fit together, from servers and virtualization to IP addressing and DNS. This section builds the foundation needed to interpret what’s happening in the field and in the NOC when services slow down, break, or change. You’ll connect core infrastructure concepts to real telecom components and operational symptoms.
Learning Objectives
-
Identify how servers, OS types, and virtualization support telecom site services.
-
Explain essential IP networking concepts (subnets, routing, DNS) used in day-to-day operations.
-
Recognize key telecom network components and relate traffic symptoms (latency, jitter, loss) to likely problem areas.
