VAS Experts Responsibilities:

1. Connect to the servers via SSH.
2. Add servers to Teleport.

The installation depends on the functionality being used.

VAS Experts Responsibilities:

1. SSG:
   1. Install SSG on the server.
2. GUI (if required):
   1. Install GUI on a separate server. If necessary (e.g., in test environments), the GUI can be installed on the same server as SSG.
3. QoE (for DPI functionality):
   1. Prepare a separate server for QoE.
   2. Install QoE.

The configuration depends on the functionality being used.

Client Responsibilities:

2. Provide information about the type of BRAS (L2 or L3) and the authentication method.
3. Configure billing logic.

VAS Experts Responsibilities:

For DPI:

1. Configure the interaction between modules (DPI, GUI, QoE).

For NAT:

1. Assign public IP addresses in SSG.
2. Configure the export of NAT events. Two options are available:
   1. To the client receiver.
   2. Use the VAS Expert solution — QoE with NAT Flow functionality.

For BRAS:

1. Configure SSG based on the type of BRAS (L2 or L3).
2. Collaborate with the client on necessary attributes in the RADIUS server response.
3. Debug and test business cases (e.g., blocking, Captive Portal, financial blocking).

Client Responsibilities:

1. Prepare a portion of traffic or a list of test subscribers for verification.

VAS Experts Responsibilities:

1. Integrate SSG with a portion of real traffic or subscribers.
2. Test the system's functionality.
3. Address any identified issues.

Client Responsibilities:

1. Confirm that the system operates according to the requirements.

VAS Experts Responsibilities:

1. Finalize the configuration and transfer the system into operation.
2. Provide support during the implementation phase.
