Fixed-line Communications Service Initiatives
SoftBank Corp., the company that operates the fixed-line communications business, is working to strengthen its business continuity structure to provide highly reliable, high-quality support and services even during unforeseen circumstances. By strengthening the resilience of its equipment, SoftBank endeavors to provide stable network services in the event of a disaster.
Strengthening equipment against disasters
Robust network center equipment
As a communications operator, SoftBank is taking all possible disaster prevention measures to ensure that facilities containing communications equipment are built to be resilient against earthquakes, fires, power outages and other disasters.
Disaster prevention measures
Facilities are built to withstand an M 7-class earthquake.
|Provisions for power outages||Two power sources are secured even during usual operation times, but in the event of an emergency and power outage, uninterruptible power sources (batteries) and emergency power generators can supply electricity for 48-72 hours.|
Transmission line redundancy and multi-routing
Fiber-optic cables and communication transmission line systems laid across Japan are designed and installed for redundancy so traffic can be rerouted in the case of an outage. This strong resilience against outages supports the networks of the SoftBank Group.
Distributed network centers
Network centers are distributed throughout the regions of Japan, primarily in the major cities of Hokkaido, Tohoku, Kanto, Tokai, Kansai, Chugoku, Shikoku and Kyushu.
