The comBOX Virtual Leased Line service bundle is the most comprehensive solution and enables the implementation of many modern applications on a corporate network.

Using Virtual Leased Line technology, together with the installation of a comBOX network appliance, comBOX VLL effectively aggregates bandwidth of available connections both at upload and download and creates a virtual leased line of high reliability for all types of traffic to and from the internet. The choice of many different providers for the individual WAN connections used ensures comBOX VLL service bundle's reliability. Even when a specific individual connection goes down it is isolated and the service is not interrupted.

Data traffic is routed through the comBOX network server located in a high speed datacentre within the European Union. It provides a new static IP address that can be used by remote users to connect to locally hosted servers. For more complex installations there is the possibility of assigning more than more IP address.

Two versions of the comBOX Virtual Leased Line are offered: Premium and Economy. The Economy version features a virtual leased line with symmetrical upload and download speeds. Where higher download speeds are required, the Premium version aggregates the full bandwidth to offer asymmetric download/upload speeds.
