5-2 Access Manager 2000 User Manual
Functionally, the node is the network management connection. It’s often
synonymous with the controller. It provides a point of access between
Access Manager and the circuit elements it manages. As far as Access
Manager is concerned, often the controller is the node.
A controller can take one of three physical forms. It can be:
■
an integral physical part of a standalone CSU
■
an integral physical part of a CSU element in a multiline shelf
■
an electrically independent module in a multiline shelf
Standalone CSUs are also referred to as single-line CSUs.
Each controller has specific CSU circuit elements with which it can be
used. A controller with its CSUs is referred to as a parent node. In Access
Manager, the parent node’s name is used to refer to the controller.
Table 5-1 Parent nodes and their components
Nodes composed of standalone CSUs are shown with the lightest shading. Nodes
with independant controller modules are shown with darker shading. Nodes which
use a controller integrated with a CSU on a multiline shelf are not shaded.
Some of the more typical arrangements of shelves, nodes, and circuit
element are shown in the following figures.
