Telkom prepares for rainy season

Heavy rains and electrical storms are expected across South Africa, and Telkom is taking precautions to minimize network problems

Telkom today said that they are gearing up to minimise network related faults caused by heavy rains and electrical storm activity.

“Flooding could cause faults but it also restricts workmen from accessing the fault zone, causing delays in repair times,” Telkom said.

“We have embarked on an extensive programme to ensure network reliability and resilience during these adverse weather conditions. This includes an extensive campaign, during the months leading up to the rainy season, where Telkom ensured the insulation of all exposed and vulnerable cable joints,” says Theo Hess, Telkom Managing Executive for Network Field Services.

“Telkom is also mobilising all available technicians to work additional hours in order to address outstanding faults as expeditiously as possible,” says Hess.

Whenever there is a thunderstorm, it is possible that lightning, or electrical power surges caused by lightning, may damage one or more of your computer components with excessive voltage. Modems are especially susceptible, because a harmful power surge can reach the modem in two ways – through the electrical power grid and through the telephone line to which the modem is connected.

Customers are advised that when there is a thunderstorm, all electronic devices (especially computers) should be unplugged to avoid damage from harmful power surges. Not only should all power supply cables be unplugged, but also any telephone cables that are connected to the computer.

A lightning protection unit– also known as a surge suppressor – can help reduce the risk of damage. Some commercially available lightning protection units have additional sockets to protect against power surges that travel through the telephone line.

However, while lightning protectors can add extra protection from power surges, it is important to note that the best possible protection is by unplugging all power supply cables and telephone cables.

A telltale sign that a modem has been damaged by a power surge is that the computer reports “no dial tone,” even though the modem is properly connected to a telephone line. The computer may also report that the modem is “not responding.”

In other instances the indicator lights on the modem do not illuminate. If other components have been damaged, you may find that the computer will not operate at all. If any of these symptoms occur soon after a thunderstorm, it is highly likely that one or more computer components have been damaged by a power surge.

“While the bad weather is likely to prevail, we will intensify our efforts to ensure that interrupted services are repaired timeously,” says Hess.

Hess advises customers that once they have obtained a reference number after reporting a fault, they do not need to call Telkom again as the Company’s internal systems will manage all the faults and ensure that repairs are done.
