Hyderabad: BSNL cellphone customers from the Telugu states suffered disruption of services for about 16 hours, since Wednesday night, due to failures in the telecom circle's Intelligence Network and Out-band servers.
The problem began at 10 pm on Wednesday. Customers had to put up with crossed lines, signal disturbance and unclear voice connection. The problem continued till Thursday morning.
The technical problem in the Intelligence Network’s Home Location Register (IN-HLR) and, later, problems in the Outband server, meant customers were unable to make calls to other networks till 2 pm on Thursday.
Official sources said that lack of optimisation of servers and maintenance in the circle office caused the problems in both the In and Outband server.
“The staff under concerned DGM and DE can optimise the servers by the simple method of logging into the admin panel and selecting ‘optimisation’ option. This should be done at least once a week. But for months, no optimisation was done,” the source said.
BSNL has 1.1 crore Cellone mobile customers in Telangana and Andhra Pradesh. “The TS and AP circles together have a revenue of at least two crore per day through Cellone. Due to the problems in the network for about 16 hours, the losses to the corporation will be at least `1 crore,” the source said.
Chief General Manager of BSNL L Anataram told this newspaper that engineers have been working to rectify the problem since Thursday morning and the situation was normal by this afternoon. “We are verifying the reasons for the failures in IN and Out-band,” he said.
