F - Firmware download for both local and remote equipment: allows the firmware
download to be done, for future upgrades. The download can be for either the local as for
the remote modem.
10.5. Configuration Menu
In this configuration menu the user has access to all information of the equipment.
All configurations made in the sub-menus of this equipment are saved in a user memory, which will need
to be activated in order for the equipment to be configured in the desired manner. The configuration in use
on the equipment will be stored in a memory called Equipment Memory. The user’s configurations
however, will be in a memory called User Memory.
Figure 22. Configuration memories diagram
Figure 22 presents all actions that can be taken with the equipment memories.
•
Equipment memory: configuration in use in the equipment, coming from the configuration
stored on the E2PROM memory after initialization (X*) or of the configuration of the user
(User memory), after the activation command (2). The equipment memory is passed on to
the E2PROM memory when “save configurations on E2PROM” (4) is selected and is
passed on to the user memory with the command “Refresh configurations” (3)
•
User memory: contains the configurations the user locally programmed via terminal or
remotely via SNMP. It is where the information of what has been configured on the
terminal screens is stored. The user memory is passed on to the equipment memory
when it is selected “apply changes” (2), then if the configurations are valid, they will
become active. The command “charge E2PROM configurations” (5) will charge into the
user memory the configuration stored on the E2PROM memory. It can also be used to
load into this memory the standard factory configuration by using the command “load
standard factory configuration” (6). The standard configuration is factory programmed and
cannot be altered.
•
E2PROM Memory: it’s a non volatile memory from where the equipment reads the
configurations on the moment of initialization (X*). This memory is copied into the User
Memory through the command “Load E2PROM configurations” (5) and is altered through
the command “Save configurations to E2PROM” (4), which activates the configuration of
the user, and sends the Equipment Memory to E2PROM.
