On the Qowisio interface, the operator is able to see alarms and

alerts, generate reports, carryout data analysis .

Use for remote access and monitoring of fuel level of critical

sites (BSC, MGW/MSC).

It indicates the diesel level of the generators on the site

The generators can be remotely switched on or off

It can indicate abnormal fuel drop

Google earth is used in EMTS NOC to search for location of a site

for fault management and other troubleshooting

Google Earth is a virtual globe, map and geographical information

program.

Google Earth displays satellite images of varying resolution of the

Earth's surface,

it allow users to see things like cities and houses looking

perpendicularly down or at an oblique angle

People use the applications to add their own data

Is a monitoring tool used to monitor the transmission tunnel of the network.

With PRTG, network operators can know if the network is running fine, who and

what is using the network bandwidth, if something is wrong with the network.

With the PRTG, operators would be able to troubleshoot network problems, before

it causes downtime or economic loss.

PRTG can monitor:

Bandwidth could be monitor using SNMP, packet sniffers

Availability of the network devices websites or data bases

system parameters like CPU load, memory usage

Virtual servers, VOIP connections and so on

With PRTG, distributed monitoring is made easy by using remote probes

PRTG MONITORING TOOL

04/18/2023 24

operators can access and configure PRTG using the web interface and

window screen

PRTG MONITORING TOOL GUI

04/18/2023 25

Data presented on the PRTG, CAN help operators to spot network usage,

trends, loads peaks and so on, this may be very useful when new hardware

or bandwidth is to be bought

PRTG MONITORING TOOL

The structure of EMTS NOC is put in place to ease;

Interoperator and operator to vendor relationships through clear

metrics and detailed report extractions

collaboration to support SLA negotiation and improve decision

making

Generally when a failure is noticed through the monitoring tools,

the front office personnel escalate them to the back office

engineers/FSE for action/resolution before customers are

impacted.
