ITM SNC 6
ITM SNC is an element management system that supports SONET NEs such as
the Lucent Technologies’ DDM-2000, FT-2000,
SLC
®
-2000, and the Fujitsu
®
Lightwave Multiplexer (FLM). ITM SNC provides fault, provisioning, configuration,
and security management functions via a Graphical User Interface (GUI). Through
these functions, ITM SNC is able to support communication multiplexing or
concentration, to provide network security, and to record all database changes.
ITM SNC also provides a cut-through capability, allowing the ITM SNC user to
access an NE through its native command set.
ITM SNC operates as an enhanced graphical tool and as a general configuration
management aid. It provides NE, port, cross-connection, and path provisioning,
as well as flow-through from provisioning operations systems (OSs) to NEs. ITM
SNC also provides fault management through subnetwork alarm and event pre-
processing prior to sending fault information to a network surveillance system
such as the Network Monitoring and Analysis-Facility (NMA-F).
IAO LAN Interface 6
DDM-2000 OC-3 R13.0 and OC-12 R7.0 support an IntrAOffice LAN (IAO LAN)
interface for operations data communications. The IAO LAN is necessary to
support the following ITM SNC R5.0 features:
■ ITM SNC as the TL1-GNE for DDM-2000
■ ITM SNC software download to DDM-2000.
*
Because the IAO LAN is effectively an extension of the SONET DCC, the IAO
LAN may also be used to join multiple, otherwise separate subnetworks. All NE-
to-NE OI features that are supported by DDM-2000 OC-3 R13.0 and OC-12 R7.0
over the DCC are also supported over the IAO LAN.
The IAO LAN interface is a software-only enhancement to DDM-2000 OC-3 R13.0
and OC-12 R7.0. The current DDM-2000 overhead controller (OHCTL) circuit
packs already support the IAO LAN interface (via an RJ45 connector).
DDM-2000’s IAO LAN interface is compatible with 10BaseT Ethernet hubs
operating at 10 Mb/s over 4-wire twisted pair cables (per Bellcore GR-253, ANSI/
IEEE 802.2 [ISO 8802-2] and ANSI/IEEE 802.3 [ISO 8802-3]).

* This feature will be useful when upgrading from DDM-2000 OC-3 R13.0 and OC-12 R7.0 to
subsequent releases.
