HSCN business applications suppliers


This page provides details of suppliers offering replacement overlay or business application services. It is part of the HSCN business applications guidance and is aimed at all organisations moving to HSCN from N3.

Historically, the N3 and Transition Network service provider (BT) delivered a small number of business application services also known as “overlays” as a set of catalogue options for consumers. These comprised:

  • N3 Voice - Hosted Voice Services (HVS) and Local Gateway Services (LGS)
  • N3 Video Conferencing (VC) services
  • N3 Remote Access Solution virtual private network (VPN) tokens
  • N3 Other Overlays - including routers, cards, ports, managed firewalls, WiFi and local area networks (LANs) 
  • N3 Site to Site VPNs (Tunnels)

As a customer migrates from N3 to the HSCN each N3 contracted overlay service will require individual actions. Full guidance on replacing these services can be found on the N3 overlays replacement guidance.

Business applications by supplier

The table below lists the HSCN business application services offered by each supplier, their contact details and links to further details of the services they offer.

This is not an exhaustive list. Details of other suppliers can be found on the CCS Network Services RM1045 ‘Suppliers by Lot’ and G-Cloud website

Detailed guidance on procuring replacement services can be found under the Main routes to market for overlay replacements section of the N3 overlays replacement guidance page.
