I am an investigator researching a case involving a Siemen telecommunication system that operates in excess of 1500 telephones. I was wondering if a dumb question could be asked of any experts regarding this system.
Do Siemen systems utilize memory cards/chips such as PC3200 64×64 DDR, Micron 512 mb pc133 (64×64) SDRAM, Hynix PC133 256 mb SDRAM (32×64), etc.?
Additionally, if these types of memory cards/chips are utilized in Siemen systems, how many would be needed and how often would they need to be replaced in a system with approximately 1500 telephone lines?
Any assistance would be greatly appreciated. I humbly thank you in advance.
