# Connectivity

Before we dive into the details of each product — **nbn TC4**, **nbn Enterprise Ethernet (EE)**, **Telstra Ethernet Access (EA)**, and **AAPT Fibre** — it’s important to understand **who is responsible for what** when delivering and supporting these services.

Each service involves multiple parties — **Hosted Network**, our **upstream provider** (nbn, Telstra, or AAPT), and **you as our partner/customer**. To ensure smooth delivery, ongoing support, and a clear escalation process, we’ve created a **Responsibility Matrix**.

This matrix outlines:

* The specific roles and tasks handled by Hosted Network
* What the upstream carrier is responsible for
* The actions and checks expected from you as the partner/customer

By reviewing the Responsibility Matrix first, you’ll have a clear picture of where responsibilities lie. This will help speed up issue resolution, improve communication, and set the right expectations throughout the service lifecycle.
