Division 4.3.3.1 Availability Management

The main service that the Service Provider has to provide is to ensure that the CCN/CSI system is ‘up and running’ at the required availability level.

The Service Provider ensures that all CCN/CSI sites are interconnected through a Wide Area Network (WAN) offering the necessary resilience and capacity to ensure the proper functioning of critical business applications using the CCN/CSI infrastructure and services.

The availability management service covers the following items:

• global access in all connected NAs;

• the provision of the local loop (+ a backup line) between the WAN local access point (PoP) and the National Administration premises;

• the Customer Premises Router (CPR) installation, configuration, and maintenance;

• the Security Device (i.e. SSG encryption-firewall box) installation and maintenance;

• communication gateways located on the DMZ, at every local site (i.e. CCN Gateways);

• the central CCN Mail III system.

The Service Provider also provides statistical information on the availability collected under operational circumstances and a monitoring service, both for pro-active problem tracking and statistical purposes.
