Telecom Egypt IM System

Inventory Management — Developer Documentation

What is IM?

The Inventory Management (IM) system is one of three core components in Telecom Egypt's OSS Service Fulfillment solution. It acts as the central repository for all service and resource inventory data — storing what customers have, what network resources are assigned, and tracking every change through its lifecycle.

IM sits between Order Management and Activation Management in the OSS stack

Core Responsibilities

📋

Service Inventory

Receives work orders from OM and stores all provisioned service data — customer info, service parameters, and assigned resources.

🔧

Resource Inventory

Manages physical and logical network resources (DSLAMs, ONTs, ports, VLANs, IPs). Syncs periodically from Matrix/eMatrix.

🔄

CFS/RFS Mapping

Automatically maps Customer Facing Services (CFS) to Resource Facing Services (RFS). No manual configuration required.

📝

Audit Logging

Logs all data modifications, user logins, role/org changes, and query operations for compliance and debugging.

Key Design Constraints

📝

IM only receives work orders from OM

IM does not connect to CRM or external systems directly for order intake. All work orders arrive exclusively from the Order Management (OM) system.
📝

No voice support in this release

IM does not support voice services in the current Telecom Egypt deployment.
📝

No suspend/resume workflows

There are no suspend or resume cases. Work orders are either TO-DO or Finished.
📝

No direct device connectivity

IM does not connect to network devices (DSLAMs, OLTs) directly. Resource data is synchronized from Matrix/eMatrix.
