IP Connection to Comfone's backbone via one of the 1250 points-of-Presence (PoP's) located worldwide is dependable and predictable. With enhanced access, Comfone's responsability does not terminate at the nearest PoP, but may also include management of the router at the customer's premises.

Coverage
Built on a globally redundant infrastructure, Comfone's IP backbone extension has been specifically designed to provide business-grade services and a congestion-free environment to mobile operators, as well as to support any future IP or 3G applications.

IP Connection to Comfone's backbone via one of the 70 Points-of-Presence (PoPs) located worldwide is dependable and predictable. With enhanced access, Comfone's responsibility does not terminate at the nearest PoP, but may also include management of the router at the customer's premises.

Access
Enhanced access, established using a leased line and router either arranged by Comfone or the customer, provides connectivity to the root DNS information and access to the Comfone backbone.

The router is installed at the customer’s premises and connected to their border gateway (BG). A leased line is connected from the router to the chosen PoP, which is the entry point for the Comfone IP backbone network. Both router and leased line are actively monitored and subsequently managed by Comfone's Global Network Management Centre, ensuring operators optimum availability and efficiency.

Quality of Service (QoS)
The Comfone service is fully compliant with appropriate GSMA rules. QoS parameters provided on the Comfone backbone include:
• Network site availability at the PoP
• Backbone network transit delay (round trip delay worldwide)
• Network throughput (or packet loss)

A Service Level Agreement (SLA) ensures high Quality of Service.

Online reporting
Comfone's Online Reporting tool enables customers to monitor utilisation and performance via secure User-ID and password Internet access. The comprehensive reports support operators in forecasting business trends and making business decisions, which can help to increase efficiency and planning for future needs.


Security
• Network Security: The Comfone IP network has been designed to meet the security requirements of GSM operators. The network on which Comfone's Data services are implemented is 100 % separate from the public Internet. Additionally, the public IP addresses used are not advertised outside the members of the community.

• Payload Security: Theoretically, payload can be encapsulated multiple times by the end-user, network operator or service provider. Multiple encapsulations generate a significant overhead and thus larger volumes. The consequence of this is higher costs for no added security. With Comfone data services, the payload (user data) does not need to be encapsulated (e.g. with IPsec) on the Comfone backbone. This is because it is built on a private network with built-in security.
