NCM Overview
1-2 Verilink NCM 2000
NOTE: Do not mix NCM and SCC Node Controllers in the same node. There
can be only one type of node controller in a node. Any existing NCC
controller card in a node will defer to the NCM when it is added and
will become another T1 application module.
Features Summary
The NCM 2000 is purely a management module. It does not operate
as a CSU or DSU. However, it may control clocking functions. NCM
tasks and features include:
• Fault management
• Configuration of all application modules in a network of
AS2000 nodes
• Circuit manager and bandwidth management—real-time
circuit building/routing support including drop-and-insert and
bypass
• Alarm management with up to four trap hosts
• Performance monitoring and management
• Diagnostics and troubleshooting
• Security management using four levels of password access
protection
• Management of legacy and newer ACP bus applications
• Provides both internal and external clock support
Features Detail
Major features of the NCM 2000 include:
Automatic
Discovery and
Restoral
When initially plugged into its node, the NCM automatically
“discovers” the elements in the node. In restoral mode, a new
application module that replaces a previously configured like
module in the same shelf/slot position (or a module that has been
cleared of its configuration) is automatically reconfigured by the
NCM from the NCM database. This restoral includes circuits that
made use of the module that was replaced or cleared.
In restoral mode, an unconfigured module is downloaded with a
complete configuration from the NCM node master database. The
node master NCM shares its database with all other shelf master
NCMs in the node.
