which one of the eTOM documents  are you looking for? there are two types of memeber ship available, if you become a free subscriber you can download NGOSS, SID and some of other documents for free

be more specific I might be able to help,

just to add that you can also download our J2EE implementation of eTOM and NGOSS process architecture our link www.ossj.org

Common API is also the J2EE implementation of SID model

documents and API specs are available for download

Thanks for your reply. I mainly need the document named: Enhanced Telecom Operations Map® (eTOM) The Business Process Framework For The Information and Communications Services Industry - GB921 v4.0

I downloaded OSSJ but I think it lacks an overall spec which is referred to eTOM, Actually I need a document that defines requirements of a typical telecom company and the way the community categorized these requirements into software systems.

I provide a conclusion but first briefly,

eTOM categorized the business processes that are used by service providers. it does nto define the process, but only categorize them. it allows you to elimitae duplicate functionalities among the enterprise and relate the related processed into one or more set of class or processes. NGOSS at the same time it defining core elements of this process map in a technilogy neutrial architecture and this architecture is based on managed entities that their relationship is defined using abstract information model SID (shared information data). OSSJ has implemented these architecture based on J2EE and is providing set to APIs for different telecomm functional areas such as PM, FM and other processes defined by the abstract definition. SID implementation can be found in OSSJ Common API.

I agree that some of the APIs are not fully aligned together, but work is in progress to make this resolved.

Conclusion: As you see based on above, you can not find any requirements for telecomm enterprise applications because in general you need CM, FM and PM areas but then features that you are providing is up to yourself and you can not find such level of requirements in eTOM in another words it is not defined in this concept.

I recommend you to join the forum to have access to whatever you need also all the training that you might require.

some companies have already implemented their OAM based on OSSJ even though some are still in implementation phase and a couple still in design discussion.

I have one document form Sun Microsystems that explains the use of J2EE in network managemen systems, but I need to find it in my documents.

Nokia has also provided an OAM which is partially based on OSSJ and it is opensource if you are interested

I am afraid you need to become a member to have access to the forum's documents  and I recomment you to do so. but above was for helping you to go to the right direction.

eTOM and OSSJ is the correct way to do it and it is emerging quickly and lot of effort has been put into it.

I have uploaded a file with name "Telecom Network Management with EJB" (ok I just forgot the name). again, this is not related to eTOM but could come in use in term of some architecture overview for telecom applications.

one more time, functional requirements are not discussed in eTOM. The concept reviews the abstract technology neutral architecture along with NGOSS and SID.

also I apologies for any typos, I rarely use spell checker in yahoo

I have uploaded the eTOM document in this address http://groups.yahoo.com/group/j2eelist/files/eTOM/ (I have just this version) , a brief description for others who want to know more about eTOM :

Every business has standards and best practices, even the sprawling, rapidly changing telecom industry. The most widely used and accepted set of standards for this sector of the world communications market is ETOM, which stands for Enhanced Telecom Operations Map. The enhanced part of the title illustrates the focus on cutting-edge telecom technologies, such as DSL, broadband, and Internet-related telephony.
ETOM is a blueprint for telecom companies to implement enterprise practices
Topics are generally broken down into three groups:
Strategy, Infrastructure, and Product: including marketing and offer management, service development and management, resource development and management, and supply chain development and management
Operations: including customer relationship management, service management and operations, resource management and operations, and supplier/partner relationships management
Enterprise Management: including strategic and enterprise planning, enterprise risk management, enterprise effectiveness management, knowledge and research management, and financial and asset management
For more information you can refer to eTOM document.
