A Network Operations Centre (NOC) analyses problems, performs troubleshooting, communicates with site technicians, and tracks problems through resolution, escalating as appropriate. For severe conditions that are impossible to anticipate, such as a power failure or a severed optical fibre cable, Gtelecom NOC has procedures in place to immediately contact technicians to remedy the problem.

Primary responsibilities of Gtelecom NOC personnel may include:
   Network monitoring
   Incident response
   Communications management
   Reporting

At Gtelecom NOC we have multiple tiers which reflect the skills and experience of our personnel. A newly hired NOC technician might enter Tier 1, whereas a technician with several years of experience may be considered Tier 3 or 4. We often escalate hierarchically within Gtelecom NOC before contacting a site technician or other network engineer. If an issue has not been resolved within a specific time frame, the next tier is informed to speed up problem remediation.

At Gtelecom NOC engineers have several duties to keep the network running smoothly. They deal with difficulties such as DDoS attacks, power outages, network failures and routing black holes. They ensure the core network is stable by configuring hardware in a way that enhances network security whilst still providing optimal performance.

Gtelecom NOC engineers also perform basic functions including remote hands, support and configuration of hardware (such as firewalls and routers purchased by a client). They monitor activity such as network usage, temperatures etc. They also install and set up equipment such as racks, KVMs and IP-PDUs and run cables. The majority of NOC engineers are on call and have a five to seven day rotation, working different shifts.
