Power supply variations cost telephone company millions per event

Due to its sheer size and geographical coverage, a telephone company incorporates vast amounts of data exchanges dependent on electrical systems. A large telephone company calculated that its systems’ inability to cope with power surges or dips costs around €24 million per year for this type of event. Power variation issues are more likely to affect the remote and generally older local exchange facilities. These, as well as being less resilient, also cost more to service than more accessible units. The overall cost is based on the additional service calls to clients following power supply variations or interruptions.
