Telecom Technology Stack

For Enterprise class large projects Architecture frameworks like TOGAF are very important:
Read
TOGAF: The Open Group Architecture Framework was adopted and adapted to E-TOM framework or Enhanced Telecom Operational Map (E-TOM) .
E-TOM has two essential layers which cover most requirement on Telcos
{Telecom companies include (TEM) Telecom Equipment manufacturer like (ZTE, Cisco Ericsson  , Telecom Services companies like ( vodaphone, O2 etc)}.
1. Lowest Level 1: OSS (Operational System Software) which include systems which interfaces with most devices like routers, base station, towers, etc Cisco routers, Base station BTE software, NOS (network operation planning software), Activation Software, 2G, 3G stack management, tower management.
2. Upper layer: BSS (Business System Software) Which includes Business Interfacing software like Oracle Sieble CRM (Customer Relationship management ), Billing software like from Amdocs,or oracle BRMS (Billing and revenue management  software)
MIS and BI Business Intelligence software like OBIEE, SAP BO, Cognos BI etc.
Mediation: Software mediating between multiple layers.
Activation:
Now lets see like BT working on E-TOM. For software implementations
British Telecom (BT) use agile methodology of keeping inventory of requirements as low as possible to keep cost down and know defects early in life cycle and then more requirements (User Stories) can be taken for development , taken to testing in SIT system integration testing and once tested OK dropped into production.
Scrum meetings are regularly held , as release happen the Burn down charts are updated telling progress status.

BT having incorporated concepts in between like
use RFT (Right First Time) 90 % of the project taken up must be completed in correct specifications in right time.
Concept to Market (C2M):Bring Concept to market faster.
Lead To Cash: (L2C)
where a lead generated to Cash in hand cycles are (Opportunity, Quotation, Order, Delivery, Issue, Invoice) L2C cycles are captured in workflow and quickened.
