Description
The MX77 Firmware Download loads firmware to the EEPROM of the
Unified Processor (UP) (NTMX77AA) card. This card is on the main shelf
of the Remote Switching Center-SONET (RSC-S) configuration.
Firmware changes can require equipment upgrades. Enhancements to and
maintenance of multiple versions of EPROMs can increase costs. There is a
method for the upgrade of firmware that can control costs. This method
controls the cost to prepare, send, and change EPROMs on all cards. This
method does not require the return of all EEPROMs on current UP cards
equipped with a previous firmware version.
Operation
The UP contains flash memory chips. The UP upgrade occurs after an
image load. The image load resembles the load of software from a host
switch. There are two flash EEPROMs or banks on the NTMX77AA card.
Each bank is a 256-kb programmable chip. One bank is in the executable
mode and the other bank is in the loadable mode. The EEPROM that
executes random access memory (RAM) is the executable EEPROM. The
EEPROM used for support is the loadable EEPROM. If the executable
EEPROM is corrupt, the loadable EEPROM takes over and becomes the
executable EEPROM.
The current LOADPM command from the MAP terminal can start a
download when a new firmware load occurs.
