Alcatel 561x
CMIP/CORBA Network OSS Interfaces
The Alcatel 561x CMIP/CORBA Network OSS Interfaces, formerly the 81x CMIP/CORBA*,
open the door to numerous integration opportunities, enabling service providers
to deliver sophisticated services based on flowthrough operations.
The Alcatel 5611 CMIP Network OSS Interface (CMIP) is a common management
information services (CMIS)/TMN-compliant OSS (operations support system)
gateway.
The Alcatel 5612 CORBA Network OSS Interface is a common object request
broker architecture (CORBA)/JIDM-compliant OSS gateway.
The 561x interfaces enable a peer network manager or OSS to interoperate with
a 5620 Network Manager, formerly the 46020 NM*, in a multivendor environment.
The functions and object model of the 561x are based on specifications from the
International Telecommunications Union (ITU) and the TeleManagement Forum (TMF).
The 561x interfaces allow an OSS to perform operations that include path
management, alarm management, inventory management and test management.
OSS Integration
The Alcatel 561x Network OSS Interfaces provide the key OSS integration
portal into the Alcatel network. The 561x interfaces maintain a model of the
network in their object oriented management information base (MIB) and make this
information available to other OSSs using standard protocols. The 561x MIB is
synchronized in real time with the network via the 5620. The 561x extends the
Alcatel strategy of interoperability, permitting other vendors' systems to
interact with the 5620 network to:
- manage events and alarms
- create, modify and delete paths
- obtain network inventory and status
- discover a network's topology
- manage statistics collection
- perform diagnostic and test access operations
Some of the network objects that can be accessed through the 561x Network OSS
Interfaces include:
- network (supply network or network partitions)
- groomed circuits (or 5620 paths)
- facilities (or 5620 links)
- groomed circuit termination points (or 5620 path-ends)
- facility termination points (or 5620 logical or physical link endpoints)
- managed elements (nodes), equipment holder (shelves, card slots), managed
packs (cards)
Through the 561x an OSS application can quickly and cost-effectively
provision connections across an Alcatel network or isolate and manage network
problems.
Applications
Automation of management processes
The 561x Network OSS Interfaces are powerful tools for automating connection
management, surveillance and other operations processes. For example, network
alarms could automatically trigger external processes, such as customer
notification.
Multivendor integration
The 5620 Network Manager's multivendor capabilities can be extended to OSS
systems using the 561x. This allows all OSS applications to access third party
equipment.
Path and link management
Through the 561x, an OSS application can manage all the connections that are
maintained by the 5620 Network Manager.
The 561x Network OSS Interfaces can perform such management operations as:
- create and delete paths and logical links
- perform loopbacks, split-back, split-through and monitor diagnostics on
paths
- dynamically change bandwidth attributes
- configure links protocol type on frame stream circuits
Alarm surveillance and event management
The 561x interfaces generate alarms and event messages in X.733/X.734 format.
An OSS application can select the alarm and event types to be logged to the OSS.
An OSS application can monitor:
- 5620 alarms to report path link and equipment failures
- 5620 activity switches
- 561x OSS Interface alarms
- node power supply failures
- loss of synchronization on a node
- 5620 path and link status changes
The 561x has a programmable event filter to log specific event report
messages in the 561x Network OSS Interface event log and to determine which
event report messages are forwarded to the OSS.
Inventory
The 561x Network OSS Interfaces maintain an inventory of the equipment in the
Alcatel network. Addition, removal or status changes affecting relevant
equipment are immediately mirrored in the 561x MIB. Indication of these changes
may then be forwarded to the OSS via event reports.
Network objects represented in the 561x Network OSS Interface MIB:
- Partition
- Equipment (node, card, shelf, power supply and fan)
- Termination points (path endpoint and link endpoint)
- Links
- Paths
Test management
Automated test integration
The 561x OSS Network Interfaces let network managers test paths and logical
links in 5620- managed networks using industry-standard protocols.
Diagnostics
On- and off-node diagnostic support allows an OSS to initiate, modify and
stop tests on network paths. The 561x Network OSS Interfaces provide a method
for the peer management system to initiate and control testing on network paths
and frame relay links. Release 4.0 also supports diagnostics for ATM virtual
path connection (VPC) links and virtual channel connection (VCC) paths.
The following test types can be performed on an Alcatel network:
- Split-through testing
- Split-back testing
- Monitor testing
The 561x Network OSS Interfaces make it possible for an automated test system
to manage maintenance connections for a path under test, and to manage
maintenance circuits between a digital test head and a node's test access point.
The automated test system or OSS can integrate 5620 testing with third party
testing systems.
Redundancy
The 561x interfaces can be used in the following redundancy configurations:
- one OSS connected to one 561x Gateway Station connected to a redundant
5620
- one OSS connected to multiple 561x Gateway Stations connected to a
redundant 5620
- multiple OSSs connected to multiple 561x Gateway Stations connected to a
redundant 5620
The 561x provides an event log object that maintains a programmable filter.
This filter can be used to select specific event report messages to be logged or
forwarded to the OSS application.
Developer support
Experts within the Alcatel Open Interfaces Professional Services group can
work with OSS developers to integrate the 561x Network OSS Interfaces with OSS
applications. Some of the services include:
- how-to Q&A
- proactive design advice
- interoperability testing
- courseware (theory and practice)
- consulting services (developer support)
- IST, NPI and development phase problem resolution
