Physical Settlement in case of Calendar Spreads

i want to know how are the Calendar Spreads settled if it goes ITM?

eg. lets assume HDFCBANK is trading at 1615. and i have 1600 CE Short for Current Month and 1600 CE Long for Next Month

you will be liable to deliver the shares at the end of the expiry this month.

For net-off to happen both option contracts should be of the same expiry.

In the above scenario, you will have to give delivery of underlying shares for the current month contract.

The next month contract will continue to trade as is. There will be no give/take delivery obligation.
