Pay protection of non pensioner ex servicemen (ssco)

Dear Esteem Members, I am a retd. short service commissioned officer. Served from 2007 to 2012 and retired in Mar 2012. In June 2014 I joined a bank with starting basic pay of Rs.17,100/-p.m. in the scale of Rs.17,100-1000(11)-28100-EB-1000(4)-32100-1100(1)-33200 applicable to Officers in Grade ‘A’. Further pay protection as per govt. guideline was assured. My last pay drawn in the forces is as under BASIC 18240.00 ** GRADE PAY 6100.00 ** MSP 6000.00 ** DA (65%) 19721.00 ** Total: 50061.00 My Pay in the Bank was re-fixed by giving 04 additional increment as under BASIC 21100.00 ** GRADE ALLOWANCE 1500.00 ** DA (97.5%) 22035.00 ** Total: 44635.00 Is the above fixation correct? I could not understand how the pay protection was done. Request esteem members expertise and advise in this regard please.
