until DDM-2000 OC-3 Release 13.0 and later, and OC-12 Release 7.0. For DDM-
2000 FiberReach 3.0 and later, Tellabs TITAN 5500/S R5.0 DCS, or other-vendor
NEs that adhere to Telcordia Technologies GR-253, can be the TL1/X.25 GNE.
DDM-2000 FiberReach can not be a TL1/X.25 GNE itself.
Autonomous and command/response messages are supported. Detailed
information about the DDM-2000 OC-3 or OC-12 X.25 interface and detailed
information about the input and output parameters for TL1 messages is provided

ITM SNC
6
ITM SNC is an element management system (EMS) 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 TL1/X.25
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 (TL1) 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 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 Bellcore’s
Network Monitoring and Analysis-Facility (NMA-F).
