are available with extensive on-line help features. The CIT interface supports
operations, administration, maintenance, and provisioning (OAM&P) activities
such as performance monitoring (PM), on any and all network elements (NE) in
the SONET subnetwork from a single DDM-2000.
An optional graphical user interface and provisioning (CPro-2000) tool is also
available. Using CPro-2000, which runs on an MS-DOS
*
PC, a user can take
advantage of the graphics to do many provisioning related activities. The
DDM-2000 CIT and CPro-2000 are described in Chapter 6, “Operations
Interfaces.”
The third operations tier consists of the remote OS interfaces. The OS interfaces
include TL1/X.25 and an IAO LAN interface.
The DDM-2000 OC-12 Multiplexer supports a full-featured TL1/X.25 interface to
multiple OSs. The DDM-2000 OC-12 Multiplexer supports alarm surveillance and
PM with OSs, such as Bellcore's Network Monitoring and Analysis (NMA) OS.
The DDM-2000 OC-12 Multiplexer supports automated service provisioning with
memory administration OSs, such as Bellcore's Operations System Intelligent
Network Element (OPS/INE) and Lucent’s ITM SNC. The DDM-2000 OC-12
Multiplexer also supports remote recovery and control functions, installation
provisioning, and security over the TL1/X.25 link.
As an alternative to DDM-2000 serving as a TL1/X.25 GNE, ITM SNC R5.0 can
serve as a TL1-GNE via an IAO LAN interface. DDM-2000’s TL1/X.25 and IAO
LAN interfaces are described in Chapter 6, “Operations Interfaces.”
The SLC

-2000 Access System supports the same X.25 and IAO LAN interfaces
and TL1 message set as the DDM-2000 OC-12 Multiplexer. The SLC -2000
Access System adds digital loop carrier (DLC) specific functionality to the existing
TL1 messages (for example, for DLC related alarms) and in addition supports
DLC specific TL1 commands (for example, DS0 level provisioning). See 363-208-
000, SLC-2000 Access System, Applications, Planning, and Ordering Guide , for
more information.
