Circuit Manager
This chapter describes how to build circuits using the NCM Craft
interface. Topics covered are:
• Central Circuit Manager concept
• Limitations to the product
• Key definitions
• Adding and editing circuits
• Activating/deactivating a configured circuit
• Other general task functions available through the Circuit
Manager menu, such as deleting and searching for circuits
NOTE: Circuit building done by connecting directly to other modules is not
documented in this chapter. When an NCM is present in a node, only
the NCM Central Circuit Manager should be used to build circuits.
Cautions The following must be considered when you are using an NCM to
build circuits:
• If you are integrating an NCM with a node that has application
modules with pre-existing circuits, the circuits must be
cleared before using the modules with the NCM or building
new circuits with the NCM Circuit Manager.
• While the Shelf Type option under the Administration Menu
determines which ACP bus the NCM will use, it also is used by
the CCM to determine bus architecture. The Shelf Type
selection must accurately reflect the actual shelf type for each
shelf in the node. See the section
“Set Shelf Type” in Chapter
3.
• If an NCM is moved from one node to another node, it will try
to build the circuits it has stored in the new node. To avoid
configuration errors, delete all circuits from an NCM card
before moving it to a new node.
• Circuits can only be built within a shelf (no data bus
extensions between shelves are possible).
• An ISDN port can be a destination port only, not a source port.
• Modules must be present in the shelf at the time their circuits
are built.
• If a circuit terminates in a DIU 2130/DDS or a DIU 2130/DBU
module (two modified versions of the TABS-based DIU 2130
DSU), it will not be restored when the DIU card is removed
