HSCN technical guidance

The HSCN Internet Access Form

The HSCN Internet Access Form replaces the Data Security Centre (DSC) HSCN ANM Firewall Change Request Form. 

The form can be used if:

• your CNSP has advised the port you are trying to access is not an allowed any/any port and you still require access
• your CNSP has advised you are trying to access something that has been blacklisted but you still require access - these requests will only be approved in exceptional and business critical circumstances
• you had access to a site on the Transition Network (previously N3) but you do not have the same access on HSCN

Once completed, the form should be sent to the NHS Digital National Service Desk (NSD) via your local IT support route. When they get the form the NHS Digital DSC will assess the request and either, instruct Capita to make the necessary changes and confirm this to you or respond to advise that the request cannot be authorised.

HSCN QoS change request form

To request a change to a QoS configuration, download the change request form.

On the form, provide as much detail as you can, including: full contact details; information about the application and the reason for the configuration change; and the QoS class, IP address, and port/protocol (if applicable).

Email the completed change request form to the NHS Digital National Service Desk (NSD).

For further details and guidance see HSCN QoS - change requests and end-to-end configuration.

HSCN customer requirements discovery form

The HSCN customer requirements discovery form has been designed to support organisations migrating from the Transition Network to HSCN in capturing and consolidating information regarding their existing network estate and IT services.

The aim of capturing this information is to allow organisations to record what connections and services will be impacted by their migration to HSCN and prompt them to consider what replacement or new services they will require their HSCN CNSP to provide.

Information captured can be used to inform discussions with your chosen HSCN CNSP.
