Firmware Hierarchy
Firmware is the software that is hard-coded into XMU+ control and line cards. You
should gain a brief understanding of the XMU+ firmware hierarchy in order to navigate
through the XMU+ configuration menu displayed on the Front Panel of the XMU+.
About Partitions
The XMU+ is often set up for a single user (single partition mode), who uses it as a
single, large, call processing system. However, when the XMU+ is set up in multiple
partition mode in a shared environment, the XMU+ is turned into several virtual
systems, with each partition acting as an individual unit. The number of partitions that
the XMU+ can be set up for (up to 64) is limited only by the amount of recording time
installed.
To determine whether your XMU+ unit is configured for single or multiple partitions,
see To check for system par tit ioning on page 84.
For more information, see:
 Main Menu Hierarchy - Single Partition Mode on page 76.
 Main Menu Hierarchy - Multiple Partition Mode on page 79.
Main Menu Hierarchy - Single Partition Mode
When the XMU+ is operating in Single Partition mode, the following configuration
structure represents the Front Panel Main Menu, from which all configuration
commands originate. There are four Main Menu categories in the XMU+ firmware:
 Messages - used to record, delete or play messages.
See Message Menu Hierarchy - Single Partition Mode on page 77 for more
information.
 Cards - used for card setup and Starting Node.
See Card Menu Hierarchy - Single Partition Mode on page 77 for more information.
 Nodes - used to create the call flow.
See Node Menu Hierarchy - Single Partition Mode on page 78 for more information.
 System - Used to define system parameters, settings and maintenance.
See Node Menu Hierarchy - Single Partition Mode on page 78 for more information.
