1.3.4 EMS Function
The central Element Management System (EMS), which system administrators access via a
GUI-based application suite (the AB-NetAccess client software), is run on a Pentium class
computer under Windows NT. The EMS allows the user to configure, control, and monitor all
components of the AB-Access System. EMS software elements include:
• SQL Database
• Java GUI Interface
• CORBA Object Infrastructure.
1.3.5 System Configuration Selection
Before installing a new unit or upgrading a unit, the network manager must know what
configuration option to use. This is important for both static and dynamic installations. The
upgrade process will place a unit in a certain state. The state of this unit will be very important
depending upon whether the unit is already being used in production or about to be put into use.
Units in production will need to be upgraded and placed back into production using the
configuration currently in place. New units will require the proper configuration in order to
come online fast and efficiently. This whole process relies on the fact that the units are
programmed properly.
Units operating in static mode will want to retain this mode. Selecting the wrong configuration
may result in a static unit being placed in a dynamic registration mode, making it potentially
unmanageable remotely. Similarly, upgrading a unit running in a routed topology to a bridge
topology will have a significant impact on functionality.
Contained in each system software release is a file that lists the possible configuration options.
The file is called “configurations” and looks similar to Tables 1-1 and 1-2.
This file is split into
two tables, one for the AP and one for the SU configurations. These tables are used to
determine which configuration the unit will be programmed in after upgrade.
For the purposes of network and software configuration, the AB-Access Extender units appear as
static point-to-point SU units. They support Ethernet or ATM wired interfaces. CLIP, RFC1483
and native ATM are supported static configuration for these units. An AB-Access Extender
point-to-point link consists of two Extender units, a Head End Unit (“AP”) and an Upstream
Subscriber Unit (“SU”).
