Network Management and Service Level Agreements

Q-KON Network Operations (NOC) Centre

The Q-KON NOC maintains a central management centre with network management systems and network engineers supporting networks across Africa. Q-KON has extensive experience in providing mission-critical network management for our customers and is the primary network control point for our customers' enterprise networks.

Network management functions applicable to our customers are monitored via Network Management Services (NMS) platforms. These are integrated NMS platforms with software/hardware tools to track and monitor all aspects of network activities and the performance of the network.

Hardware management

All warranties on equipment supplied will be supported by Q-KON on a swap-out basis for the length of the warranty. All equipment is covered by a one-year warranty period.

Q-KON recommends that the customer hold a suitable quantity of spares onsite where services are provided in remote, inaccessible regions where shipping and travel delays could prolong downtime.   All faulty equipment must be shipped to Q-KON for replacement (if under warranty) following any maintenance or repair work. Following the repair or replacement of parts, Q-KON will ship the equipment to restock the customer spare-holding. All costs to effect same will be for the customers account. Q-KON recommends that critical components be spared onsite to avoid downtime as a result of shipping delays.

Service Level Agreements (SLA)

Q-KON offers a full support contract for the VSAT services covering ongoing maintenance, monitoring and spares management with guaranteed service levels. Q-KON via the SLA will provide a minimum availability guarantee of the 99.5% on a monthly basis. The Guarantee is applicable to the availability of the following network components: (1) The satellite hub & teleport.  (2) The satellite communication channel.  Q-KON will provide a service level agreement for the VSAT equipment at the site provided spares are kept onsite at the customer's premises. Failing this, repairs are subject to the availability of spares.

Should the customer opt to keep spares at the site, Q-KON will guarantee a restoration time of 4 hours from the arrival of the engineer onsite. Every attempt is made to resolve problems through the normal support centre, however at times engineers will be required to travel to the site if it cannot be restored remotely.
