NCM Overview
This document describes the Access System 2000 (AS2000) Node
Controller Module, NCM 2000, Verilink’s SNMP solution to
managing digital wide area networks.
Applications
This document provides information specific to the NCM 2000:
• Introduction, features, and general information
• Hardware and system overview
• Using the NCM Craft interface
For information about specific applications that can be managed by
the NCM, see the appropriate application manual.
The NCM 2000 is a networked intelligent module that is devoted
exclusively to management tasks. It has no data-carrying tasks
other than its use of inband management via the data lines. The
NCM is IP-addressable and can be fully integrated with an AS2000
network.
The NCM contains an embedded Craft interface (ASCII terminal
interface) that allows a system administrator to control, configure,
administer, and monitor application modules in the local node and
in remote NCM-managed nodes of an AS2000 network.
The NCM also has an embedded SNMP agent that acts as a host for
the optional Node Manager or any other SNMP-based network
manager. (The Verilink Node Manager product is an optional
Graphical User Interface-based manager application that runs
under Windows 95/NT.) SNMP, Telnet and FTP protocols are
supported through Ethernet and SLIP connections.
Network Node
Management
A major feature of the NCM is that a local NCM Craft interface
session can access up to 30 other nodes in an AS2000 network.
Then you can manage elements in those nodes as if each were in
your local node, through sessions that the Craft interface
establishes to NCM modules in the network. These sessions
communicate via inband management channels connecting a
network of AS2000 nodes. Inband management channels are
provided by dedicated DS0 lines within the T1 or T3 lines
connecting the nodes.
