Bharat Sanchar Nigam Ltd is expecting a 20-25 per cent surge in its domestic long distance traffic volume following a 47 per cent cut in STD rates earlier this week.

"We are anticipating a volume surge of 20-25 per cent in the NLD traffic following the rate cut, so the loss could be offset by this", Prithipal Singh, chairman and managing director, BSNL, said in New Delhi on Thursday today at a telecom seminar.

He, however, declined to comment on the quantum of the hit the corporation would have to take following the cut, saying we do not calculate it beforehand and whatever it is, the volume would make up for it.

To a query whether any further rate cut is expected, he said it could be in basic tariffs, adding that BSNL is to file shortly its new tariff packages with Trai.

"Very shortly, it could be today as we need a 10-day discussion period after filing it with them", he said while replying as to when the corporation would file it with Trai.

BSNL is likely to file in all three to four alternate packages for basic services, besides the standard tariff package.

The corporation is not likely to propose any hike in the rentals in the alternate tariff packages, at least for exchange capacity of 100,000 and above.

BSNL had earlier said that it is working out alternate tariff packages with "flexibility and value additions", for its subscribers.

BSNL this week announced a 47 per cent cut in domestic long distance rates to Rs 4.80 during peak hours from the current Rs 9 per minute.
