The document provides an overview of the Telecom Applications Map (TAM) in conjunction with the TM Forum's Frameworx, detailing various frameworks like NGOSS and their components. It outlines how TAM is structured into horizontal layers and vertical columns, emphasizing its mapping to SID and eTOM domains for application integration. The document also discusses interoperability between applications via TM Forum interfaces and recommends an architecture based on service-oriented principles for effective application development.

TAM A Repository of Reusable
Best Practices

7. 7- TAM is mapped to eTOM & SID domains. A TAM domain is decomposed into application area.
- Each application area is mapped to SID level 1 ABE and eTOM level 2 process
Application Framework - TAM

8. 8
 Application Framework (TAM) is divided into seven (7)
horizontal layers- (in consistent with SID). It is also divided
into four (4) vertical columns— (in consistent with eTOM).
 Each box on the map represents a level 1 application such
as Customer Order Management or Bill Calculation.
 Each application area of the Framework is further
decomposed into lower levels of functionality down to the
application level.
 TAM is mapped to eTOM & SID domains. Each application
area is mapped to SID level 1 ABE and eTOM level 2
process
Layers of Application Framework (TAM)

9. 9
 Integration Framework supports interoperability between applications
defined in TAM via TM Forum interfaces.
 Interfaces are defined in terms of SID’s entities/attributes, & requirements
for interfaces that come from eTOM.
 TM Forum recommends for Application Neutral Architecture (ANA)/
Technology Neutral Architecture (TNA).
 TM Forum recommends for SOA based architecture/solution to achieve
following: reusability & decoupling
 TM Forum recommends to use following for applications development
methodologies: OSS/J, MTOSI etc.

SID & Application Integration Framework

11. OSS/J- Prospero – mTOP
Prospero:
Prospero is interface standards between BML, SML, NML and EML
Prospero is the TM Forum brand for “solution packs”. CO~OP, IPDR,
mTOP and OSS/J contribute to develop solution packs.
mTOP:
mTOP is TM Forum program to define interface specifications for Resource
and Service management with respect to fulfillment and assurance. It is
comprised of two specification products:
1) MTNM (NMS-EMS, CORBA-based interface) and
2) MTOSI (OS-OS, XML-based interface).
OSS/J and mTOP alignment
OSS through Java™ (OSS/J) is TM Forum program to define:
Java, XML, and Web Services-based APIs.
