To understand interpretation of notice period clause as per Mumbai university statute

Mumbai University statute reads S.237 Notice for Leaving the Service (1) The teacher shall not leave or discontinue his/her service in the College or Recognized Institution without giving prior notice in writing to the Competent Authority of his/her intention to leave or discontinue the service. The period of such notice shall be (a) three calendar months in the case of a permanent teacher. (b) one calendar month in the case of a temporary/ adhoc or probationary teacher. (c) In case of breach of these provisions, the teacher shall pay to the College or Recognized Institution an amount equal to his/her basic pay for the notice period required to be given by him/her. In case he/she fails to pay the amount, it shall be recovered from the dues payable tc him/her. (2) If the Disciplinary Authority, after completing the procedure of departmental enquiry. comes to the conclusion that the teacher should be compulsorily retired or removed from service, it shall give three months' notice in case of a permanent teacher or pay the basic pay for the period in lieu thereof. (3) The Competent Authority shall not terminate the service of the teacher on probation without giving him/her one month's prior notice in writing or one month basic pay in lieu thereof. Is it correct to interpret that we can provide one month notice service and 2 months salary in lieu of notice service as combination? Also here word basic - does it assume to include DA also ?
