I know that by overspecifying the number of cycles will go into the useful life of the equipment so is there a guideline to tell us what's the limit? And for temperature ESS what is the acceptable rate of change of temperature?

The sinario is: 1. The network consists of 1 centre site + 4 remote sites A,B,C&D. 2. The configuration on all remoted sites are same. 3. Any remoted site failure doesn't affect the operation of other r-sites and centre. The question is - the system availability of this network shall consider : a. all sites (ie. 1+4), or b. 1 centre + 1 remote site. (ie.1+1) c. 1 centre + 2 remote sites in nCr (4C2) (ie. 1+2) d. others, pls advise. Thank you. Teng YL
