Optical line 4 months Even after 4 months, 20,000 cases are not available

　In mid -May, the NTT West Internet optical line service occurred in mid -May, causing a cumulative 60,000 installation work to be delayed, and about 20,000 cases were still delayed four months later.It is unusual for the use of online line, which can be said to be a living infrastructure, is affected for a long time in tens of thousands of units.The voice that was sent to the West Nippon Shimbun "Your Special Interview Team" turned out to be found in the wake of the voice.

　Due to the delay in construction, the contractor has not been able to use the Internet or telephone, and has a major impact on daily life.It is said that construction has not been done even more than six months after applying.

　According to NTT West, troubles occurred in May when the "construction reception system", which entered the contractor's desired date and address, was updated.Before the renewal, the work of unifying the notation of the phone number was thoroughly enforced, and about 63,000 data could not be transferred.

　This system is connected to multiple management systems, such as customer service usage status, and it has also been found to be bugs in the collaboration setting between systems.It took about two months for the correction work, and the stagnant construction resumed in earnest in July.

　As the trouble continues, NTT West resumed the acceptance of new construction on June 8.With the increase in processing projects, cases in which construction is postponed further.There are still about 20,000 cases, including new acceptance, that the installation work has not yet been decided.

　According to the Ministry of Internal Affairs and Communications, the enforcement rules of the Telecommunications Business Law stipulate that communication failures that affect "2 hours or more and 30,000 users" are "serious accidents."The trouble has had a significant impact equivalent to these provisions, but the ministry states that it is not a communication equipment trouble.

　NTT West apologized, "We apologize for the inconvenience, and we apologize."However, pointing out that the reception has increased the confusion has only been explained that "it was a management decision."

　Professor Koji Okamura of Kyushu University, who is familiar with telecommunications technology, said, "As the demand for optical lines increases rapidly due to the spread of work from home, etc., the troubles in which new use delay will be reduced as a company that will lead the social infrastructure. In addition to early solutions, the cause is thorough.He pointed out that it should be investigated and disclose measures to prevent recurrence. "

　NTT West system troubles that occurred during the new colon viruses and online classes and online classes, and the demand for optical lines increased.Despite the hindrance to the lives of the contractor, the response is insufficient, including the affected linkage businesses, and "Your special coverage group" is "the Internet environment is important infrastructure of life. The Ministry of Internal Affairs and Communications is the Ministry of Internal Affairs and Communications.There are a lot of criticism and dissatisfaction with strict guidance.

　There are 10 related information sent to the interview group.Of these, NTT DOCOMO have seven contractors from DOCOMO Hikari, which use the NTT west line as a coordinator.

　In March, a man in his 50s in Fukuoka City applied for a relocation work of "DoCoMo", which was in use, with a new construction of his home.I was involved in May trouble without confirming the construction schedule.If you contact the contracted docomo for the construction outlook, you will be told that the construction schedule depends on the NTT west, and the NTT west will only say, "Contact the contractor's docomo."The answer was the same no matter how many times I contacted.

　During this time, we borrowed wireless communication equipment on our own, but we abandoned the online lesson of the piano instructor's wife due to lack of capacity.The son of a college student could not take the online class smoothly.In August, I switched to another company without waiting.Men are indignant, saying, "I didn't think it was a very responsible business."

　NTT West said in the interview, "If the construction date has not been determined before the trouble, it will be the corresponding business operator (such as docomo)."According to DOCOMO, "I worked with NTT West every day, but the explanation to the customer may have been partially inadequate."
