INM not only provides for surveillance but also provides for provisioning,
performance monitoring, shelf level graphics, protection control, centralized
software management, and inventory collection. INM provides a single point
of operational access for multiple S/DMS TransportNode OC-3/12/48/192
subnetworks, S/DMS AccessNode, SONET Radio, DV-45, Tellabs Titan 5500
Digital Cross-Connect systems (DCS), OC-3 Express, JungleMUX, INM
NETWORKS NEs as well as Nortel ATM Passport Network Elements and
potentially other network elements through a graphical consolidated view

Common Object Request Broker Architecture
An Overview
Common Object Request Broker Architecture (CORBA) is a multi-vendor
standard for object-oriented distributed computing. CORBA technology is
based on specifications defined by the Object Management Group (OMG)
which is a consortium of computing involved companies. The OMG is an
international organization of over 600 members, and includes all of the major
vendors of systems and software from around the world, as well as
independent software vendors, large and small consulting companies, and an
increasing number of end user companies.
The OMG only produces specifications and not software. The specifications
are freely available for any company to implement. An implementation of
CORBA is referred to as an ORB (Object Request Broker). There are many
ORBs in the marketplace today, Nortel has chosen Orbix, from Iona
Technologies as its distributed middleware CORBA technology to provide the
capabilities to develop distributed applications around its INM Broadband
Release 4.1 product.
Rapidly changing technologies, increased complexity and need for
responsiveness to customer needs have led telecommunication service
providers such as Nortel to explore new and novel methods for deploying new
telecommunications systems and networks. As a result, the telephony world
has devoted a significant amount of time developing architectures such as
Telecommunications Management Network (TMN).
Concurrent with efforts made in the telecommunication world, the computing
world has been developing and refining concepts, architectures and platforms
such as OMG CORBA that enable software modules to cooperate and
communicate transparently across different implementations of operating
system, hardware and networks.
