Wired telecommunications carriers own, operate, and maintain physical network infrastructure — fiber optic cable, coaxial systems, copper lines, conduit, switching equipment, and data centers — to deliver broadband internet, voice, and video services to residential and business subscribers. Day-to-day operations involve network monitoring, field technician dispatch for installation and repair, equipment maintenance at central offices and remote nodes, and management of subscriber billing and service agreements.
Questions to investigate
- What types of infrastructure does the carrier own and operate — fiber, coaxial, copper, or a combination?
- What is the approximate replacement value of the network infrastructure, including buried plant and central office equipment?
- What mix of residential versus business subscribers does the carrier serve, and are there formal SLA or uptime commitments in business contracts?
- What cybersecurity controls are in place — network segmentation, endpoint detection, incident response planning?
