# Customer & Subscriber Management – Overview

**Product:** i2i Core OSS/BSS  
 **Company:** i2i Tech Services Private Limited

---

## Purpose

 The Customer & Subscriber Management module is the foundation of i2i Core OSS/BSS. It establishes the authoritative identity and ownership model used across AAA, provisioning, billing, reporting, and audit flows.

## Conceptual Model

- **Customer**: Legal/commercial entity (individual/organization/partner).
- **Account**: Billing & service container under a customer.
- **Service**: A provisioned offering (broadband, leased line, add-ons) owned by an account.
- **Subscriber**: End endpoint/identity consuming the service (credentials + network identifiers).
 
## Lifecycle

1. Create Customer → Create Account
2. Attach Service(s) to Account
3. Create Subscriber identity and map it to service
4. Activate → Operate (Modify/Suspend/Resume) → Terminate
 
## Operational Principles

- **Data integrity first**: Avoid duplicates and uncontrolled edits.
- **Controlled state transitions**: Changes must be lifecycle-aware.
- **Downstream impact awareness**: Customer data drives AAA & billing behavior.
- **Auditability**: All changes must be traceable to a user and time.
 
## Role Responsibilities

- **L1/NOC**: Create customers/accounts, routine updates, status checks, basic lifecycle actions.
- **L2 Ops**: Validate AAA/provisioning dependencies, handle complex corrections safely.
- **L3/Admin**: Policy, configuration, integration, and defect triage.
