2 AS8300 Element Manger
The AS8300 Element Manager (EM) is an Operations and Management System, a
computer based network management system for the AS4000 System that does not use a
GUI based screen presentation.
The Element manager can control a number of systems (including the remotely located
STs).
The AS8300 EM is designed to offer the necessary functionality to manage a large AS4000
sub-network and be located in a central Operations and Maintenance environment away
from the rest of the system. It uses the X.25 packet switched data network to communicate
with the Central Terminals (CTs) within the network.
Each Shelf Controller (SC) within an CT communicates via a serial port to an X.25 PAD
that serves the four modem shelves in a CT Equipment Rack. (see Figure 22).
