ECS allows transfer of funds electronically and it is generally used to give a mandate to banks for honouring periodic claims from the entities concerned.
"We have received notification from RBI with regard to extension of window for acceptance of ECS mandate till May 31, 2016. Hence the acceptance of ECS mandate shall be discontinued with effect from June 1, 2016," BSE said in a circular.
Earlier the deadline was till April 30.
In March, BSE had announced a host of new services on its mutual fund platform, BSE StAR MF, including digital non-demat transactions, round the clock order acceptance and six-day order holding facility to help investors and distributors of such products.
The move was aimed at allowing mutual fund distributors to leverage the stock exchange platforms to expand their reach.
