Figure 1-1 Mixed Shelf with Mirrored Node Managers and NCMs
Circuit Manager
Database
The Circuit Manager uses a database which is stored in the NCM
card. This database contains the configuration and circuit
information for the entire node. It is sometimes referred to as the
Central Circuit Manager.
Shelf
Compatibility
The NCM is compatible with the AS2000 plug-in modular shelf
system. The NCM can replace an NCC or SCC module as the node
controller module. It can manage all modules controllable by the
NCC or SCC in legacy AS2000 applications.
NOTE: If an NCM is placed in a Dual-line shelf, it should be in slot two of the
shelf.
NOTE: The DIU 2140, DIU 2130/NMS 56K and DIU 2131 modules may be
configured with the NCM, but SNMP error messages are not
supported. The SCC 2120 and TAC 2120 Automatic Protection
Switch modules are not supported by the NCM, instead the NCM
offers backup functionality through the Circuit Manager function.
