1.3a MP10 SYSTEM MEMORY MANAGEMENT
In previous OfficeServ Systems such as the OfficeServ 100, 500, and 7200, SRAM
memory stored the active system database and Smart Media was where the Database
was saved on a more permanent basis. The SRAM was battery-backed on the MCP10
card by a super-capacitor with a battery backup switch which could clear the memory
and default the system. However, the memory architecture of the OfficeServ 7100 with
the MP10a is different.
The OfficeServ 7100 equipped with an MP10 processor has 4 types of memory:
1) SRAM (2MB): Holds information such as Call Logs, Alarms, UCD call stats,
program logs and traffic reports. SRAM is backed by the Super Capacitor on the
MP10. If switch is ON, data can last up to 1 day without main system power.
2) DRAM: This is where active system Database resides. During IS Tool or KMMC
programming, the data being programmed is written to DRAM.
DRAM IS CLEARED WHEN SYSTEM BOOTS. During system boot up, the latest
SRAM contents are reloaded into DRAM.
3) MMC+ (256MB): When you use MMC 815 and save the Database to MMC+, it
copies the active Database from DRAM and saves it to MMC+ Card. This way the
most up-to-date database is saved to MMC+ Card. This way the most up-to-date
database is saved to MMC+ Card.
WHAT THIS MEANS TO YOU?
From the information described above, you can see that if you made a
programming change in KMMC and pressed the right soft key to save, the change
is made immediately to DRAM and the change takes effect immediately. Likewise, if
you make a programming change using IS Tool and click the SAVE button, the
change is effective immediately and is saved to DRAM active system database.
